ETHNOPHARMACOLOGICAL RELEVANCE The West African tree Keetia leucantha (Rubiaceae) is used in traditional medicine in Benin to treat malaria. The twigs dichloromethane extract was previously shown to inhibit in vitro Plasmodium falciparum growth with no cytotoxicity (>100µg/ml on human normal fibroblasts). MATERIALS AND METHODS The dichloromethane and aqueous extracts of twigs of K. leucantha ...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
One triterpenic acid (ursolic acid), one phenolic acid (rosmarinic acid), and four flavonoids (luteolin, luteolin 7-O-(6”-feruloyl)-β-glucopyranoside, luteolin 5-O-β-glucopyranoside, and luteolin 7-O-β-glucuronide) were isolated from the aerial parts of Thymus sipyleus subsp. sipyleus var. sipyleus and identified by spectroscopic methods. In vitro lipid peroxidation inhibition effects of the co...
Among the triterpenoids, oleanolic acid (OA) and its isomer, ursolic acid (UA) are promising therapeutic candidates, with potential benefits in the management of melanoma. In this study, we aimed to examine the in vitro and in vivo anti‑invasive and anti‑metastatic activity of OA and UA to determine their possible usefulness as chemopreventive or chemotherapeutic agents in melanoma. For the in ...
Antihypertensive herbs in scientification of “jamu” program in Indonesia contained Centella asiatica (L.) Urban. The leaf contains several compounds such as triterpenoids, flavonoids, phenolics, tannins, and resins. The total triterpenic fraction of C. asiatica could treat venous hypertensive microangiopathy, while ethyl acetate fraction of C. asiatica leaf has hypotensive effect in cats. This ...
Outcome: Phytochemical investigation of Cyperus rotundus tubers resulted in isolation of four phytoconstituents characterized as n-tritriacontan-16-one (1), Lup-12, 20 (29)-dien-3β-ol-3-α-L-arabinofuranosyl-2'-octadec-9"-eonate (2), npentadecanyl-9-octadecenoate (3) and n-tetradecanyl-n-octadec-9, 12-dienoate (4). Only compound 2 showed antimicrobial activity. Lup-12, 20 (29)-dien-3β-ol3-α-L-ar...
