[Studies on the chemical constituents of Rubus suavissimus S. Lee].
OBJECTIVE
To study the bioactive constituents from leaves of Rubus suavissimus S. Lee.


METHODS
Column chromatography with silic gel was employed to isolate and purify the constituents. Their structures were elucidated by means of IR, MS, NMR and chemical methods respectively.


RESULTS
Two consituents were obtained, which were elucidated as ent-13-hydroxy-kauran-16-en-19-oic acid (I), ent-kaura-16-en-19-oic-13-O-beta-D-glucoside (II), respectively.


CONCLUSIONS
Compound II was seperated from Rubus suavissimus S. Lee for the first time.
