sitosterol/hibiscus

The genus Hibiscus contains about 275 species of flowering plants widely grown in the tropics and sub-tropics. The available literature revealed that several Hibiscus species exhibited excellent anticancer activity against several cancer cells like lung, breast, and liver. This motivated the authors

This study evaluates the antibacterial, cytotoxic activities, and phytochemical composition, of Callistemon citrinus, Hibiscus rosa-sinensis and Plumbago auriculata leaves and flowers, three ornamental plants in Mexico. However, in other countries offers a range of other uses. Ethanol extracts of C.

Seven constituents (I-VII) were isolated from the bark of Hibiscus syriacus and identified as nonanedioic acid (I), suberic acid (II), 1-octarcosanol (III), beta-sitosterol (IV), 1,22-docosanediol (V), betulin (VI) and erythrotriol (VII). VII was obtained from the plant for the first time, I, II,

OBJECTIVE To study the chemical constituents from Hibiscus syriacus leaves and their α-glucosidase inhibitory activities. METHODS Column chromatography including macroporous resins, silica gel and Sephadex LH-20 were used for the isolation and purification of all compounds. Spectroscopic methods

A new oleanane triterpenoid, methyl 27-caffeoyloxyoleanolate (2), together with eight known compounds viz. oleanolic acid, kaempferol, quercetin, beta-sitosterol-3-O-beta-D-glucopyranoside, kaempferol-3-O-alpha-D-rhamnopyranoside, gossypin, quercetin-3-O-beta-D-glucopyranoside and mangiferin were
