Fund Project: The authors gratefully acknowledge support for this work of the National Natural Science Foundation (No. 20362010) and are grateful to Mr. Y. N. He and Ms. H. L. Liang in the State Key Laboratory of Phytochemistry and Plant Resources in West China, Kunming Institute of Botany, Chinese Academy of Sciences, for measuring NMR and MS data, respectively.

A novel saponin was isolated from the transformed products of ginsenoside Rh₁ by Bacillus subtilis. It's structure was determined to be 3-O-β-D-glucopyranosyl-6-O-β-D-glucopyranosyl-20 (S)-protopanaxatriol on the basis of the spectral data.
- Ginsenoside Rh₁,
- novel saponin,
- biotransformation.
