A new abietane diterpene glycoside from roots of Rabdosia japonica var. glaucocalyx

Objective To study the diterpenes in the roots of Rabdosia japonica var. glaucocalyx. Methods The constituents of R. japonica var. glaucocalyx were separated and purified with chromatographic methods, and their structures were elucidated by spectroscopic methods. Results Two compounds were isolated from the roots of R. japonica var. glaucocalyx, and they were identified as glaucocalyxoside (1) and inflexuside A (2). Conclusion Compound 1 is a new abietane diterpene glycoside named glaucocalyxoside, and compound 2 is isolated from R. japonica var. glaucocalyx for the first time.
