Moringa oleifera is known as a drumstick tree and cultivated in subtropics and tropics. It exhibits antihypertensive and antidiabetic effects. An ultra-high-performance liquid chromatography method was developed for the determination of nine...
Parkinsonia aculeata L. growing in Saudi Arabia was investigated for its phytochemical profile, antioxidant, and cytotoxic properties. UPLC-ESI-MS/MS was employed as a powerful technique for the characterization of secondary metabolites from a...
The Moringaceae plant family includes taxonomically amonogeneric genus calledMoringa, which encompasses13 species endemic to the African, Arabian, and Indianprovinces. This book takes the reader on an enjoyable journeythat stops by four stations (...
A series of iridoid glycosides were isolated from the leaves of Lasianthus verticillatus (Lour.) Merr., belonging to family Rubiaceae. A new iridoid glycoside, lasianoside F (1), and three new bis-iridoid glycosides, lasianosides G–I (2–4), together...
A rare dimeric sesquiterpenoid (tinosposinoside, 1) and a phenylpropanoid (cordifolioside C, 2), two undescribed metabolites, were isolated from the methanolic extract of the stems of Tinospora sinensis together with thirteen known compounds. This...
Phytochemical investigation of the methanolic extract of Vangueria agrestis aerial parts led to the isolation and characterization of four monoterpene rhamnosides, two ursane saponins, and six flavonoid glycosides. Of these constituents, are three...
Tinospora species are morphologically similar. Several cases of human toxicity have been reported in association with T. crispa. A chemical fingerprint was developed to differentiate T. crispa from its closely related species and to quantitate its...
Background Moringa oleifera Lam. is known as a drumstick tree that is widely cultivated in various subtropical and tropical provinces. Previous studies indicated that both aqueous and methanolic extracts of M. oleifera leaves have potent inhibitory...
A new rearranged clerodane diterpenoid, tinocrispide was isolated from the stems of Tinospora crispa along with thirteen known compounds including eight clerodane diterpenoids. Among the known compounds baenzigeride A,(6S, 9R)-vomifoliol and...
Four ursane-type triterpenoid glycosides (1-4), two benzophenone glycosides (5 and 6), and one iridoid glucoside (7) were isolated and characterized from the dried roots of Vangueria agrestis. Compounds 1 (3-O-[α-L-rhamnopyranosyl-(1→2)-β-D-...
Fadogia agrestis is used in traditional African medicine as an analgesic and for anti-inflammatory and aphrodisiac activities. An ultra-high-performance liquid chromatography method was developed for the determination of 11 chemical constituents...
Rooibos tea (Aspalathus linearis) is a well-known South African herbal tea enjoyed worldwide. Limited reports indicate the potential of rooibos tea to alter the activity of certain cytochrome P450 (CYP450) isozymes. In this study, the phytochemical...
