| Abstract: | AIM: To investigate the chemical constituents of Rubus chroosepalus Focke. METHODS: The methanol extracts were suspended in H2O and then extracted with EtOAc. Column chromatography was used for separation and purification, while spectral analysis was used for identification. RESULTS: Seven compounds were isolated and identified as 2 alpha, 3 beta-dihydroxy-urs-12, 19-dien-23, 28-oic acid (I), 2 alpha, 3 beta, 23-trihydroxy-urs-12,18-dien-28-oic acid (IIa), 2 alpha, 3 beta, 23-trihydroxy-urs-12,19-dien-28-oic acid (IIb), 2 alpha, 3 alpha-dihydroxy-urs-12,18-dien-28-oic acid (IIIa), 2 alpha, 3 alpha-dihydroxy-urs-12,19-dien-28-oic acid (IIIb), and the acetonide of IIIa and IIIb (IVa and IVb). CONCLUSION: I was found to be a new pentacyclic triterpenoid acid. |
