摘要(Abstract):

[Objectives] To study the chemical constituents of Pilea sinofasciata C. J. Chen. [Methods] Column chromatography,such as silica gel,Sephadex LH-20 and preparative HPLC were used to isolate and purify the compounds. Spectroscopic methods like MS,1H NMR and~(13)C NMR and physical constants were used to elucidate their structure. [Results]Ninteen compounds were isolated from 95% ethanol extracts of Pilea sinofasciata C. J. Chen,including α-tocopherol(1),stigmasterol(2),epihernandulcin(3),hernandulcin(4),benzoic acid(5),ethyl linolenate(6),ethyl hexadecanoate(7),α-amyrin(8),palmitic acid(9),behenic acid(10),adenosine(11),indole-3-carboxylic acid(12),protocatechuate(13),gallic acid(14),betulinic acid(15),oleanolic acid(16),potassium nitrate(17),diosmetin7-O-β-D-glucopyranoside( 18),3-O-β-D-xylopyranosyl(1→2)-β-D-glucopyranosyl-28-O-β-D-glucopyranosyl oleanolic acid(19). [Conclusions] All of the compounds were isolated from the plant for the first time.
