New chemistry from South East Asian medicinal plants
Indonesia comprises only 1.3% of the earth's land surface, but has 11% of the world's higher plants, with over 1000 different plant extracts used in traditional medicines.  In a collaborative program on the chemistry of Indonesian medicinal plant species, we have examined the natural products chemistry of plants of the genus Durio and Fagraea. Both triterpene and lignan metabolites were isolated from Durio along with well known compounds such as 3-hydroxymellein that are characteristic of fungi. The relative and absolute configuration of a set of new neolignan metabolites (1) – (4) were explored by NMR and by CD studies. The genus Fagraea was generally characterized by iridoid glycosides, however the unusual new terpene alkaloid fagraeoside (5) was isolated from Fagraea racemosa.
