[Display omitted] • A UPLC method was firstly established to assay ten components in N. officinalis. • The content of ten phytochemicals in different parts of was greatly different. • Superior distribution and content of phytochemicals were found in the leaves. Nauclea officinalis is a Li-folk medicine in China, with antimalarial, antibacterial, and anti-inflammatory properties. However, the phytochemicals of Nauclea officinalis have not yet been comprehensively researched. In this paper, a reliable and efficient approach based on ultra-performance liquid chromatography (UPLC) with a diode array detector (DAD) was firstly established for simultaneous quantification of alkaloids, flavonoids, and phenolic acids in N. officinalis resources. The samples were extracted using ultrasound with 60 % ethanol for 20 min (1:50 g/mL), and analyzed by the developed UPLC-DAD method. Under the optimized extraction and chromatographic conditions, the proposed approach showed favorable performance in terms of the linearity (R2 > 0.9998), precision (RSD < 3.75 %), repeatability (RSD < 0.86 %), stability (RSD < 2.14 %), and accuracy (with the recovery rates between 95.15 % and 105.49 %) within an extremely short running time (12 min). Moreover, the developed approach was successfully employed in the quantification of ten phytochemicals in different parts (leaves, branches and trunks) of Nauclea officinalis. Based on analytical results, the content of ten phytochemicals in different organs of Nauclea officinalis was significantly different, and the superior contents of these phytochemicals were located in the leaves compared to the branches and trunks. In summary, the current work established an effective method for the assay of multi-compounds, which could supply a basis of the quality control and comprehensive utilization for Nauclea officinalis.

• Phenolic compounds in 70 edible flowers were determined by HPLC-UV-DAD. • Comprehensive phenolic profiles of edible flowers are plotted systematically. • Gallic acid, quercitrin, and hesperidin were widely found in edible flowers. • Rosa species possessed relatively higher phenolics than other edible flowers. Edible flowers of ornamental plants are non-toxic flowers that have been used since ancient times for their nutritional and health benefits. These health benefits are attributed to their phytochemicals such as phenolic acids and flavonoids. These phytochemicals exert positive health effects on chronic diseases such as cancer, inflammation, and diabetes. This research paper is focused on the systematic investigation of free phenolic acids and flavonoids (including anthocyanins) present in 70 commonly consumed edible flowers collected from local parks and Qingping market of Guangzhou, China. The phenolic acids and flavonoids of flower samples were determined by high performance liquid chromatography-photodiode array detector. The phenolic acids, flavones, flavonols, flavanones, and anthocyanins of different flower samples exhibit a wide range of variation. Gallic acid (1177.8–27717.2 μg/g), protocatechuic acid (66.7–9641.2 μg/g), p -hydroxybenzoic acid (43.6–1792.7 μg/g), quercitrin and hesperidin (49.9–14576.6 μg/g), and quercetin and luteolin (8.8–480.0 μg/g) were the predominant phenolic compounds in edible flowers samples under investigation. Anthocyanins were detected only in 14 kinds of flower samples and most of these flowers were of red or purple colour. [ABSTRACT FROM AUTHOR]

Modern pharmacology studies and clinical practice demonstrated that Epimedium and its active compounds possess wide pharmacological actions, especially in strengthening yang, hormone regulation, anti-osteoporosis, immunological function modulation, anti-oxidation and anti-tumor, anti-aging, anti-atherosclerosis and anti-depressant activities. Currently, effective monomeric compounds or active parts have been screened for pharmacological activity from Epimedium in vivo and in vitro. [Copyright &y& Elsevier]

Abstract: In this paper, microdialysis combined with ultra performance liquid chromatography/mass spectrometry (UPLC-MS) was applied for the determination of ligustilide in freely moving rats'' brain. The extracellular unbound ligustilide could be detected in rat brain within the first time interval (0–20min) after nasal administration but not after oral administration. This result showed that ligustilide could quickly enter the brain after nasal administration; which implied that ligustilide may have a rapid onset of action. This work demonstrated the potential application of microdialysis combined with UPLC-MS in pharmacokinetic studies. Furthermore, the advantage that fewer animals used in the microdialysis experiment was confirmed. [Copyright &y& Elsevier]

Zanthoxylum nitidum (Roxb.) DC. (Z. nitidum), which is known in China as Liang – Mian – Zhen , is mainly distributed in southern China and is widely used in traditional Chinese medicine. It is traditionally used for treating stomach ache, toothache, rheumatic arthralgia, traumatic injury and venomous snake bites. Additional medical applications include the treatment of inflammations, various types of cancer, bacterial and viral infections, gastric and oral ulcers and liver damage. This paper aims to offer up-to-date information on the botany, traditional uses, phytochemistry, pharmacology and toxicity of Z. nitidum. This review also discussed the perspectives for possible future research on Z. nitidum. A comprehensive review was carried out on studies about Z. nitidum conducted in the past 60 years by using different resources, including Flora of China , Pharmacopoeia of the People's Republic of China and academic databases. At present, more than 150 chemical constituents have been separated and identified from Z. nitidum , most of which include alkaloids. Biological activities, including anti-inflammation, analgesia, haemostasis, anticancer and antibacterial, were determined via in vitro and in vivo studies. The variations in the efficacy of Z. nitidum can be attributed to the biological activities of its natural products, especially alkaloids. Toxicity studies on Z. nitidum are relatively few, thus requiring further study. This article generalises the current research achievements related to Z. nitidum , which is an important medicinal material in China. Some traditional uses of Z. nitidum have been assessed by pharmacological studies. Unresolved problems remain, including molecular mechanisms underlying biological activities, pharmacokinetics, toxicology and therapeutic effect, which are still being studied and explored before Z. nitidum can be integrated into clinical medicine.
