Hydro-alcoholic fruit extract of Cordia myxa was considerably effective on curing acute inflammation in mouse model. Previous studies suggested significant anti-inflammatory activities as well as potential anticancer agent of α-amyrins in seeds. Inhibition of Cyclooxygenase-2 (COX-2) and

BACKGROUND The plant Launaea procumbens belongs to the family Asteraceae and traditionally used in the treatment rheumatism, kidney, liver dysfunctions and eye diseases. In the present study Phytochemical analysis and fractions of methanolic extract of L. procumbens leaves were tested in vitro for

Dandelion extracts have been studied extensively in recent years for its anti-depressant and anti-inflammatory activity. Recent work from our lab, with in-vitro systems, shows the anti-cancer potential of an aqueous dandelion root extract (DRE) in several cancer cell models, with no toxicity to

BACKGROUND α-Amyrin (a pentacyclic triterpene widely distributed in nature and isolated from a variety of plant sources and pharmacologically shown a wide spectrum of activity including anti-inflammatory, anti-ulcer, anti-hyperlipidemic, anti-tumor, and hepatoprotective actions) explored as

A new cerebroside, Contortamide (1) together with nine known compounds spegatrine (2), affinisine (3), Nb-methylaffinisine (4), ursolic acid (5), α-amyrin (6), bauerenol acetate (7), lupeol (8), betulinic acid (9) and

BACKGROUND There is only scant literature on the anticancer components of medicinal plants from Nigeria, yet traditional healers in the area under study claim to have been managing the disease in their patients with some success using the species studied. OBJECTIVE To document plants commonly used

The chloroform extracts of the roots and leaves of Sarracenia flava showed antitumor activity against lymphocytic leukemia P-388. Lupeol was identified as one constituent responsible for this activity. Beta-Sitosterol and alpha-amyrin were isolated from the hexane extract of the roots.

BACKGROUND Thymus alternans Klokov (Lamiaceae) is a neglected species of the genus Thymus (Sect. Serpyllum) endemic to Carpathian area, where it is used as a flavouring agent and for medicinal purposes. OBJECTIVE The aim of the work was to identify antiproliferative constituents from the flowering

Two new trachylobane- and one isopimarane-type diterpenoids: ent-18-hydroxy-trachyloban-3-one; ent-trachyloban-3-one; isopimara-7,15-dien-3beta-ol, were isolated from the leaves of Croton zambesicus, together with trans-phytol, beta-sitosterol, alpha-amyrin and stigmasterol. The structures were

Ten compounds, neopulchellin (1), 6α- hydroxyneopulchellin (2), β-sitosterol-3-O-β-D-glucoside (3), apigenin (4), quercitin (5), eupafolin (6), kaempferol-3-methoxy-7-O-α-L-rhamnoside (7), apigenin-7-O-β-D-glucopyranoside (8), α-amyrin (9) and β-sitosterol (10), were isolated from the leaves of

Bioassay-guided fractionation of a CH(2)Cl(2)/MeOH extract of the small twigs of Brachylaena ramiflora var. ramiflora resulted in the isolation of the two new triterpene esters 1 and 2 and five known triterpenoids, alpha-amyrin palmitate (3), beta-amyrin palmitate (4), beta-amyrin acetate (5),

An investigation of the aqueous ethanolic extract (AE) of the aerial parts of Torilis radiata Moench yielded two triterpenes (lupeol acetate (1) and α-amyrin (2)), a sterol (spinasterol (3)) from its n-hexane fraction (HF), a flavone (acacetin (4)), a coumarin (scopoletin (5)), a phenolic acid

BACKGROUND The resin of Cola nitida is used in western Cameroon as incense for spiritual protection and during ritual ceremonies. This plant secretion has never been investigated although previous chemical and biological studies on other resins have drawn many attentions. OBJECTIVE The resin

(1) Background: In China and South Asia, Alstonia scholaris (Apocynaceae) is an important medicinal plant that has been historically used in traditional ethnopharmacy to treat infectious diseases. Although various pharmacological activities have been reported, the anti-lung cancer components of A.
