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 -α-l-rhamnopyranosyl-(1 → 6)-β-d-glucopyranosyl
3-indolecarbonate (3) and α-l-rhamnopyranosyl-(1 → 6)-β-d-glucopyranosyl 3-indolecarbonate (4).
Keywords: Alkaloid; Clematis manshurica Rupr; Methyl 7- O -α-l-rhamnopyranosyl-(1 → 6)-β-d-glucopyranosyl 3-indolecarbonate; Methyl 7-ethoxy-3-indolecarbonate; α-l-Rhamnopyranos-yl-(1 → 6)-β-d-glucopyranosyl 3-indolecarbonate
