Objective: To isolate and identify saponins from Zhuang-medicine Gocaekmbaw (Gynostemma pentaphyllum) after heat-processing. Method: The leaves of gocaekmbaw were steam-heated at 125 ℃ and 0.24 MPa for 3 h
then extracted with 80% ethanol for 3 h. The extracts were isolated with chromatography using HP-20
silica gel and reversed ODS column. The constituents isolated from gocaekmbaw after heat-processing were identified with 1H-NMR
13C-NMR and LCMS-IT-TOF spectra. Result: Two different configurations of saponins were obtained from the heat-processed Gocaekmbaw. They were identified as 20 (R) -ginsenoside Rg3 and 20 (S)-ginsenoside Rg3 and there was no data reported before the present study. Conclusion: Through the method of heat-processing
ginsenoside Rg3 can be gained from Gocaekmbaw. This may offer a new direction to the preparation of ginsenoside Rg3.
