A novel pentacyclic triterpene glycoside from a resin of Commiphora glandulosa from Botswana
(African Journal of Pharmacy and Pharmacology, 2010)
A novel ursane-type pentacyclic triterpene glycoside, 1β,2β,3β-trihydoxy-urs-12-ene-23-oic-rhamnoside was isolated from the resin of Commiphora glandulosa Schinz by bioassay guided fractionation. Crude aqueous and chloroform ...
Seed dispersal by serrated tortoises (Psammobates Oculiferus) and the effect of their gut passage on seed germination.
(Researchgate, 2014-10-27)
Some tortoises are frugivores and can disperse seeds away from the parent plant to areas favourable for their establishments through gut passage. We investigated the plant species dispersed by the serrated tortoise ...
