1Department of Phytochemistry, Guangdong College of Pharmacy, Guangzhou 510006, China.
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.
Conclusion:
Compound II was seperated from Rubus suavissimus S. Lee for the first time.
