| Abstract: | OBJECTIVE To study the chemical constituents extracted from the mulberry leaf and identify its structure. METHODS The compounds were extracted with 800 mL/L ethyl alcohol, isolated by the siliga column chromatography and identified by spectrocopic methods. RESULTS Six flavonoids were isolated from the mulberry leaf and their structures were identified as b-sitosterol （ Ⅰ ）, daucosterol （ Ⅱ ） kaempferol-3-O-β-D-glucopyranoside （ Ⅲ ）, quercetin-3-O-β-D-glucopyranoside （ Ⅲ ）, quereitrin （ Ⅴ ） morin-3-O-β-D-glucopyranoside （Ⅵ）. Compound Ⅵ is obtained from the mulberry leaf for first time. |
