Fund Project: This work was supported by the National Natural Science Foundation of China (Nos. 30070905, 20872118) and the Key Lab Fund of Shaanxi Province of China (Nos. 02JS15, 04JS06, 05JS53).

Biomimetic transformation of gentiopicroside was carried out by β-glucosidase at pH 7.0 for 3 days at 37℃. Two products,erythrocentaurin and 5,6-dihydro-5-formyl-6-methyl-1H,3H-pyrano[3,4-c]pyran-1-one were isolated and identified by ¹H NMR,¹³C NMR, UV, IR, MS and elemental analyse. The possible mechanisms were discussed.
