To study the chemical constituents in the flowers and fruits of Rabdosia excisa.
The compounds were isolated and purified by silica gel column chromatography and their structures were identified by spectroscopic methods.
Sixteen compounds isolated from the flowers and fruits of this plant were identified as: stigm asterol (I), α-amyrin palmitate (II), ursolic acid (III), 2α, 3α, 19-trihydroxy-urs-12-en-28-oic acid (IV), 2α-hydroxyursolic acid (V), maslinic acid (VI), isodonal (VII), maoyecrystal E (VIII), kamebakaurin (XI), macrocalyxin G (X), epinodosinol (XI), rabdosichuanin C (XII), kamebacetal A (XIII), oridonin (XIV), enmenol-glucoside (XV), and lasiononin (XVI).
All the constituents were found in Rabdosia excisa for the first time, except constituents III, IX, XII and XIV.
