Abstract:
Objective:To isolate and purify the chemical constituents from Goodyera schlechtendaliana, and lay a foundation for further research on the effective materials of the plant. Method:The dried grass of G. schlechtendaliana(10 kg)was heated by 95% EtOH for reflux extraction for 4 times at 85℃. The extract liquids were combined, decompressed and concentrated to obtain the crude extract. The crude extract was then suspended in distilled water and extracted with petroleum ether,EtOAc and n-BuOH in turn to obtain corresponding fractions. Silica gel,Sephadex LH-20,ODS and semi-preparation high performance liquid chromatography (HPLC) were used for the separation and purification of EtOAc and n-BuOH fractions. The structures of compounds obtained were identified by 1H-NMR,13C-NMR,MS,physicochemical properties and reference literature. Result:Ten compounds were isolated and identified as 2,5-dihydroxy-4-methoxy-9,10-dihydroxyphenanthrene (1),1,3,5-trimethoxybenzene (2),protocatechuic acid (3),p-hydroxybenzaldehyde (4),p-hydroxybenzoic acid (5),quercetin (6),vanillin(7),daucosterol (8),adenine (9) and adenosine (10). Conclusion:Compounds 1-10 were obtained from the genus of Goodyera for the first time.
