To study the chemical constituents in the rare medicinal herb Oreorchas patens in Changbai Mountain for better utilization of the resource.Methods:
The drug was used as crude material, the extract was obtained with 95% ethanol firstly, and then with ethyl acetate (EtOAc). The EtOAc extract was further isolated and purified with various chromatographic methods, including silica gel, ODS, and Sephadex LH-20 columns. Finally the isolated compounds were characterized with their physical chemical properties and based on their 1H-NMR and 13C-NMR data.Results:
Eleven compounds were obtained from the EtOAc extract and identified as β-sitosterol (1), β-daucosterol (2), dioctyl phthalate (3), butyl-isobutyl-phthalate (4), diamyl phthalate (5), β-sitosterol acetate (6), dibutyl phthalate (7), dibutyl terephthalate (8), cirrhopetalanthin (9), pentacosane (10), and hexatriacontane (11).Conclusion:
