Background There are high mortality and morbidity rates due to poisonous snakebites globally with sub-Saharan Africa having some of the highest cases. However, traditional medicine practitioners (TMP) have been treating snakebites in Uganda for long despite the fact that few studies have been conducted to document such vital and rich indigenous traditional knowledge before it is lost. This study aimed to document the medicinal plant species used by experienced TMP in treating snakebite envenomation in selected post-conflict parts of Uganda. An ethnopharmacological survey was conducted in Kitgum, Serere, Kaberamaido and Kaabong districts in Uganda. Twenty-seven TMP with expertise in treating snakebites were purposively identified using the snowball technique and interviewed using semi-structured questionnaires. Data were analysed using simple descriptive statistics. Results Sixty plant species from 28 families were documented with high consensus among the isolated indigenous Ik tribe of Kaabong district. Most of the plant species used were from the Asteraceae and Fabaceae families with eight species each. The genus Echinops was the most well-represented with three species. The most commonly used plant species were of citation were Steganotaenia araliaceae (16), Microglossa pyrifolia (Lam.), Gladiolus dalenii Van Geel (13), Aframomum mildbraedii Loes. (11), Jasminum schimperi Vatke and Cyathula uncinulata (Schrad) Schinz (10) and Crinum macowanii Baker and Cyphostemma cyphopetalum (Fresen.) Desc. ex Wild & R.B. Drumm (10). S. araliaceae which was mentioned by all the TMP in the Ik community was used for first aid. Most of the plant species were harvested from the wild (68.75%) and were herbs (65.0%) followed by trees (23.3%). The most commonly used plant parts were roots (42.6%) and leaves (25.0%). Thirteen different methods of preparation and administration were used. Most of the medicines were administered orally (61.2%) and topically (37.6%). The commonest methods of oral application were cold water infusions (32.5%) and decoctions (21.7%). Conclusions TMP widely use several medicinal plant species for treating snakebite envenomation in the selected post-conflict regions of Uganda

Background: Cyathula prostrata (Blume) L. from the family Amaranthaceae has been used traditionally for rheumatism, dysentery, wounds and urethral discharges in the tropical regions of the world. Aim: The present study was undertaken to perform quality control standardization and to evaluate antioxidant activity of the leaf, stem, root and the whole plant of Cyathula prostrata. Methods: Macroscopic and microscopic evaluations were carried out on the plant using standard procedures. Powdered sample of the leaf was evaluated with various organic solvents for fluorescence. The chloroform, ethyl-acetate and methanolic extracts of the leaf, stem, root and whole plant were subjected to various pharmacognostic analyses and evaluated for in vitro antioxidant activity using DPPH assay.Further, thin layer chromatoghraphy was used to evaluate the chloroform extract. Results: Important epidermal features in the plant include: coastal cells, unbranched, uniseriate, multicellular and non-glandular trichomes. Leaves are amphistomatic showing mostly anomocytic and actinocytic stomata. Starch grains are restricted to the adaxial surface. Vascular bundles are mainly collateral and well-developed bundle sheath. The transverse section of stem is circular, hypodermis (1-3 layers). Cross section of the root is described in detail for the plant. Cortex has angular cells. Fluorescence studies showed different colours. Physico-chemical results are comparable with standards. The TLC profile showed presence of at least seven compounds in the leaf, root and the whole plant extracts, while nine components were obtained from the stem extract. The ethyl acetate extract of the root and ethanol extract of the stem gave the highest phenolic contents (30.09±3.768 mg GAE/g) and DPPH free radical scavenging activity (87.0 ± 0.208), respectively. Conclusion: The distinctive features established in this study are steps in identification, standardization and quality control of this medicinal plant.

Background This study evaluated the antibacterial activity of some plants used in folklore medicine to treat diarrhoea in the Eastern Cape Province, South Africa. Methods The acetone extracts of Acacia mearnsii De Wild., Aloe arborescens Mill., A. striata Haw., Cyathula uncinulata (Schrad.) Schinz, Eucomis autumnalis (Mill.) Chitt., E. comosa (Houtt.) Wehrh., Hermbstaedtia odorata (Burch. ex Moq.) T.Cooke, Hydnora africana Thunb, Hypoxis latifolia Wight, Pelargonium sidoides DC, Psidium guajava L and Schizocarphus nervosus (Burch.) van der Merwe were screened against Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, multi-resistant Salmonella enterica serovar Isangi, S. typhi, S. enterica serovar Typhimurium, Shigella flexneri type 1b and Sh. sonnei phase II. A qualitative phytochemical screening of the plants extracts was by thin layer chromatography. Plants extracts were screened for antibacterial activity using serial dilution microplate technique and bioautography. Results The TLC fingerprint indicated the presence of terpenoids and flavonoids in the herbs. Most of the tested organisms were sensitive to the crude acetone extracts with minimum inhibitory concentration (MIC) values ranging from 0.018–2.5 mg/mℓ. Extracts of A. striata, C. uncinulata, E. autumnalis and P. guajava were more active against enteropathogens. S. aureus and Sh. flexneri were the most sensitive isolates to the crude extracts but of significance is the antibacterial activity of A. arborescens and P. guajava against a confirmed extended spectrum betalactamase positive S. enterica serovar Typhimurium. Conclusion The presence of bioactive compounds and the antibacterial activity of some of the selected herbs against multidrug resistant enteric agents corroborate assertions by traditional healers on their efficacies.

Background Several herbs are traditionally used in the treatment of a variety of ailments particularly in the rural areas of South Africa where herbal medicine is mainly the source of health care system. Many of these herbs have not been assessed for safety or toxicity to tissue or organs of the mammalian recipients. Methods This study evaluated the cytotoxicity of some medicinal plants used, inter alia, in the treatment of diarrhoea, and stomach disorders. Six selected medicinal plants were assessed for their antibacterial activities against ampicillin-resistant and kanamycin-resistant strains of Escherichia coli by the broth micro-dilution methods. The cytotoxicities of methanol extracts and fractions of the six selected plants were determined using a modified tetrazolium-based colorimetric assay (3-(4, 5-dimethylthiazol)-2, 5-diphenyl tetrazolium bromide (MTT) assay). Results The average minimum inhibitory concentration (MIC) values of the plants extracts ranged from 0.027 mg/mℓ to 2.5 mg/mℓ after 24 h of incubation. Eucomis autumnalis and Cyathula uncinulata had the most significant biological activity with the least MIC values. The in vitro cytotoxicity assay on human hepatocarcinoma cell line (Huh-7) revealed that the methanol extract of E. autumnalis had the strongest cytotoxicity with IC50 of 7.8 μg/mℓ. Ethyl acetate and butanol fractions of C. uncinulata, Hypoxis latifolia, E. autumnalis and Lantana camara had lower cytotoxic effects on the cancer cell lines tested with IC50 values ranging from 24.8 to 44.1 μg/mℓ; while all the fractions of Aloe arborescens and A. striatula had insignificant or no cytotoxic effects after 72 h of treatment. Conclusions Our results indicate that the methanol fraction of E. autumnalis had a profound cytotoxic effect even though it possessed very significant antibacterial activity. This puts a query on its safety and hence a call for caution in its usage, thus a product being natural is not tantamount to being entirely safe. However, the antibacterial activities and non-cytotoxic effects of A. arborescens and A. striatula validates their continuous usage in ethnomedicine.

Lobova, Tatyana A. and Mori, Scott A.
- Abstract
In neotropical forests many species of plant depend on animals for pollination and seed dispersal and it has been well documented that bats play an essential role in dispersal of many flowering plants (Gardner 1977). Bats are responsible for colonization of plants into forest gaps because they often disperse the seeds of plants adapted for growth in disturbed areas. Species of Cecropia, Piper, Solanum and Vismia are especially important pioneer plants, and bats play a critical role in the dispersal of these secondary woody species into both secondary and primary forests, and into the seed bank (de Foresta et al. 1984, Lobova et al. 2003).

The insect-metamorphosing steroids (ecdysterone, inokosterone and cyasterone) and the related substance (rubrosterone) isolated from Achyranthes and Cyathula (Amaranthaceae) were assayed in terms of their ability to stimulate protein synthesis in mouse liver. High stimulation was introduced by all steroids, administered intraperitoneally, in which cyasterone showed the highest activity. Oral administration of ecdysterone produced similar activation. Ecdysterone stimulated protein synthesis not only in male mice but also in female mice.

Cancer is one of the most prominent human diseases which has stimulated scientific and commercial interest in the discovery of new anticancer agents from natural sources. The current study investigates the cytotoxic activity of ethanolic extracts of sixteen Nigerian plants the MTT assay on the HeLa cell line. Sapium ellipticum leaves showed activity comparable to the reference compound Cisplatin and greater cytotoxic activity than Combretum paniculatum, Celosia trigyna, Drymaria cordata, Cyathula achyranthoides and Cyathula prostata. Justica extensa, Pupalia lappacea, Hedranthera barteri leaves, Alternanthera sessilis, Ethulia conyzoides leaves, Combretum zenkeri root, Sapium ellipticum stembark and Lannea nigritana stembark showed very low activity while Combretum molle, Adenanthera parvoniana and Lannea acida showed no activity. The results justify the use of Sapium, Combretum, Celosia, Drymaria and Cyathula in traditional treatment of cancer.Keywords: Medicinal plants; Cytotoxicity; Cancer; Sapium; Combretum

Summary. A brief summary of the genus Pupalia has been attempted on a world-wide basis. It is shown that 'typical' P. lappacea (L.) Juss. (which is lectotypified) is the plant frequently known as P. atropurpurea (Lam.) Moq., and that the most common form of P. lappacea must be called var. velutina (Moq.) Hook. f. Four species are recognized in the genus, two new varieties of P. lappacea being described from Africa; principal synonymy and a key to all taxa is given. The plant recorded from the Philippines as P. atropurpurea is referred to P. micrantha Hauman, and three names in Pupalia are disposed in Cyathula and Alternanthera. Pupalia has, somewhat unexpectedly, proved to have given me some of the greatest difficulties in specific delimitation of any genus of Amaranthaceae hitherto dealt with for the 'Flora of Tropical East Africa'. More, these difficulties proved such that the only practical solution seemed to be to examine the genus on a world-wide basis. This survey may of course prove fallible in some ways as being merely an off-shoot of the account of Amaranthaceae for the 'Flora of Tropical East Africa'. It has been based only on the material at Kew plus types of species unrepresented there, kindly loaned from other institutions, and then tested against the collections at the British Museum. All specimens seen are in K unless otherwise stated. Airy Shaw (1973) gives the genus Pupalia as having '10 trop. Afr., Madag., India' species-a number apparently too high even on the most cursory examination of material available. The problems encountered are not unlike those found in Achyranthes-the absence of pseudostaminodes in Pupalia being more than compensated for by the presence of modified sterile flowers forming a 'burr' in the ripe fruit.

When naming some Malesian Amaranthaceae in the herbaria of the Royal Botanic Gardens, Kew, and the British Museum (Natural History), I came across isotypes of two Philippine taxa described by Merrill in the genus Cyathula. I then realized that Backer, when reducing both taxa to a single variety under C. prostrata, had created an incorrect combination, as Merrill's varietal epithet should have been given priority in that rank (cf. Art. 6o of the International Code of Botanical Nomenclature).
