An antineoplastic agent is one of the main focuses of pharmaceutical development to treat cancer disease. In silico study can efficiently reduce the time and cost of such screening anticancer agent candidates. This study aimed to screen the biological activity and pharmacological properties of potential Cyperus rotundus bioactive compounds. Five bioactive compounds contained in Cyperus rotundus, such as apigenin, aureusidin, luteolin, quercetin, and scaberin were used in this study. The biological activity of investigated bioactive compounds was analyzed using PASS (Prediction of Activity Spectra for Substances) software. SwissADME software was used to analyze the pharmacological properties of each compound. Results showed that various biological activities have a potential as anticancer of all investigated compounds including free radical scavenging, HIF-1a inhibitor, and apoptosis agonist activity. All investigated compounds except scaberin demonstrated an antimutagenic activity, TP53 enhancer, and MMP9 inhibitor. However, antineoplastic activity only showed by aureusidin, luteolin, and scaberin. Based on SwissADME analysis known that all investigated bioactive compounds showed optimum lipophilicity, size, polarity, solubility, and flexibility. But the only scaberin showed optimum saturation. Five bioactive compounds contained in Cyperus rotundus showed a promising effect as anticancer drug candidate, so it needs to be studied further. [ABSTRACT FROM AUTHOR]

Cipadessa baccifera (C. baccifera) is a plant belonging to the Meliaceae family growing in tropical areas and containing terpenoids and flavonoids. Flavonoids have antioxidant properties so they can inhibit oxidoreductase enzyme activities, such as xanthine oxidase playing a significant role in uric acid biosynthesis. This study aimed to determine the antioxidant activity, xanthine oxidase inhibition activity, and the bioactive compounds in methanol extract and the most active fraction of C. baccifera leaves using LC-MS/MS. The research was carried out in the following steps: 1) extraction of C. baccifera leaves by maceration method using methanol solvent then phytochemical test, 2) fractions separation using solvents of n-hexane, ethyl acetate, butanol and water, 3) antioxidant and xanthine oxidase inhibition test of initial methanol extract and each fraction, 4) Identification of compounds using LC-MS/MS. The results showed that the methanol extract of C. baccifera contained alkaloids, flavonoids, tannins, saponins, and steroids. The ethyl acetate fraction had the highest levels of flavonoids, antioxidant activity, and xanthine oxidase inhibitory activity, and the LC-MS/MS analysis indicated that this fraction contained quercimeritrin, kaempferol 3-0-β-D-glucopyranoside, oxofangchirine, and glehlinoside B.

The present study was carried out to analyze the possible active constituents present in the ethanolic extract of stem bark, leaves, and seeds of Sterculia quadrifida (Sterculiaceae). S. quadrifida is locally known as "Faloak" in East Nusa Tenggara Province and commonly used in traditional medicine to treat hepatitis. Its parts were collected from Kupang City, East Nusa Tenggara province. Chemical compounds were identified by Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Fifteen compounds are identified in stem bark, twenty-one compounds in leaves, and fourteen compounds in seeds that can contribute to the medicinal quality of the plant. The prevailing compounds are Tributyl acetyl citrate (35.66%), 2,6,10,14,18,22-Tetracosahexaene (20.64%) and Hexadecanoic acid (48.84%). A minor component, such as Vitamin E, is also present. Hexadecanoic (synonym - Palmitic acid) acid has been reported to possess antioxidant, antimicrobial, and anti-inflammatory activities. [ABSTRACT FROM AUTHOR]

Alpinia galanga is an important rhizomatous plant widely used as an aromatic cooking spice and herbal medicines. This study aims to describe the plant morphological characteristic of. A. galanga, examine the presence of chemical components in rhizomes through histochemical analysis and review its pharmacological potentials. A. galanga is characterized as a perennial herb; rhizome cylindrical and branched, hard, reddish brown or pale yellow-green, strong aroma; pseudostem erect, leaves lanceolate-oblong, alternate; inflorescence terminal, erect, many flowers, white or yellowish, fragrant; fruit globose to the ellipsoidal capsule, yellow-orange to red. Histochemical analysis showed that the rhizome contains starch, protein, lipid, alkaloids, flavonoids and tannins. Among the primary metabolites, lipid size is larger than protein and starch. However, the density of starch secretory cells is higher than protein and fat, approximately 23.14 ± 3.01 cells/mm2. Among secondary metabolites, alkaloids size higher than tannins and flavonoids. Nevertheless, the density of secretory cells of flavonoids is higher than alkaloids and tannins, approximately 2.24 ± 1.44 cells/mm2. This current review indicates that almost all parts of the A. galanga plant contain many bioactive compounds, including antimicrobial, antioxidant, anti-ulcer, antibacterial, antitumor, anti-HIV, antifungal, anti-inflammatory, anti-allergic and antidiabetic.
