Alkaloids from Clematis manshurica Rupr.
Three new alkaloids together with two known compounds have been isolated from the roots of Clematis manshurica. On the basis of their spectroscopic and chemical evidence, the new compounds were elucidated as methyl 7-ethoxy-3-indolecarbonate (2), methyl 7-O-alpha-L-rhamnopyranosyl-(1 --> 6)-beta-D-glucopyranosyl 3-indolecarbonate (3) and alpha-L-rhamnopyranosyl-(1 --> 6)-beta-d-glucopyranosyl 3-indolecarbonate (4).
