Title: Studies on chemical constituents from leaves of Diplopanax stachyathus
Abstract: Object To study the chemical constituents from leaves of Diplopanax stachyathus Hand Mazz aiming at searching for bioactive natural products Methods The compounds Ⅰ-Ⅹ were isolated by a combination of Sephedex LH 20 and silica gel column chromatographies, and their structures were identified by spectral methods Results Ten known compounds were isolated from leaves of D stachyathus Their structures were identified by means of spectroscopic analysis as: β sitosterol (Ⅰ), betulinic acid (Ⅱ), oleanolic acid (Ⅲ), ursolic acid (Ⅳ), daucossterol (Ⅴ), quercetin 3 O β D glucopyranoside (Ⅵ), 3,3′,4′ tri O methyellagic acid (Ⅶ), 3, 3′ di O methylellagic acid 4 O β D xylopyranoside (Ⅷ), 3′ O methylellagic acid 4 O β D xylopyranoside (Ⅸ), and 3, 3′,4′ tri O methylellagic acid O β D glucopyranoside (Ⅹ) Conclusion Compounds Ⅰ-Ⅵ and Ⅸ are isolated from this plant for the first time
