Iridoid glucosides from leaves and stem barks of Parkia javanica.
Two new iridoid glucosides, javanicosides A (1) and B (2) along with the known compounds, ursolic acid and beta-sitosterol were isolated from the leaf and stem bark of Parkia javanica and the structures were established on the basis of detailed spectroscopic analysis (MS, 1D, and 2D NMR experiments). The new compounds were identified as 8-O-p-hydroxybenzoyl-6'-O-p-coumaroyl-mussaenosidic acid (1) and 7-O-E-3,4-dimethoxycinnamoyl-6'-O-beta-D-glucopyranosylloganic acid (2).
