Anti-inflammatory activity of saikosaponins from Heteromorpha trifoliata.
1995
By means of activity-directed chromatographic fractionation using the 12-O-tetradecanoylphorbol acetate (TPA)-induced edema test, two saikosaponins were isolated from the MeOH extract of Heteromorpha trifoliata leaves. They were identified as 16 beta, 23-dihydroxy-13,28-epoxyolean-11-en-3 beta-yl-[beta-D-glucopyranosyl (1-->2)]-[beta-D-glucopyranosyl (1-->3)]-beta-D-fucopyranoside [1] and 16 beta, 23,28-trihydroxy-11 alpha-methoxyolean-12-en-3 beta-yl-[beta-D-glucopyranosyl (1-->2)]-[beta-D-glucopyranosyl (1-->3) [beta-D-fucopyranoside [2]. Compound 1 showed activity in the TPA and ethylphenylpropiolate (EPP) mouse ear edema and the serotonin paw edema tests, whereas compound 2 was active o…
Screening of tropical medicinal plants for antiinflammatory activity
1995
The antiinflammatory activity of different extracts from 16 tropical plant species belonging to 15 different families has been determined. They were administered topically on TPA-induced mouse ear oedema and orally on carrageenan-induced mouse paw oedema. In the latter, extracts from Diospyros leucomelas, Erythrospermum monticolumn, Ficus polita, Heteromorpha trifoliata, Hypericum lalandii, Kirkia acuminata, Pterocarpus angolensis and Zanha africana significantly reduced the oedema 3 h after carrageenan injection. All the extracts were considerably active when assayed topically with only three exceptions.
