Abstract:To isolate and identify the constituents from the leaves of Broussonetia papyrifera (L.) Vent.. Methods: Compounds isolation used D101 macroporous resin, silica gel and ODS column chromatography methods.Structures identification used NMR and ESI-MS techniques. Results: Seven constituents, including n-hexadecanoic acid methyl ester, n-nonadecanoic acid, dimethyl phthalate, luteolin-6-C-β-D-glycosides, luteolin-8-C-β-D-glycosides, cosmosiin and luteolin-7-O-β-D-glucopyranoside were identified. Conclusion: It’the first time of n-hexadecanoic acid methyl ester, n-nonadecanoic acid and dimethyl phthalate isolated from leaves of B. papyrifera. |
