Outline
Silica gel column chromatography, reversed phase C18 column chromatography, Sephadex LH-20 gel column chromatography, high performance liquid chromatography and medium performance semi preparative liquid chromatography were performed to separate and purify the chemical constituents of Hypericum lagarocladum N. Robson. Spectroscopic methods such as MS and NMR combined with physicochemical properties were applied in identifying the structures of the isolated compounds. A total of 11 compounds were isolated and identified as hyperlagarone A (1), hyperpatulone E (2), hyperbeanol G (3), uralione D (4), tomoeone F (5), pyramidatone A (6), tomoeone A (7), tomoeone B (8), hyperbeanol C (9), hyperbeanol A (10), and hypercohone G (11), respectively. Compound 1 is a new polycyclic polyprenylated acylphloroglucinol derivative, and compounds 2-11 are isolated from this plant for the first time. 11 compounds were tested for glucose uptake in L6 cells, and the results showed that compounds 7 and 8 had significant effect on glucose uptake.
