Objective To study the constituents from the berry of Panax ginseng. Methods Compounds were separated and purified by column chromatographic methods. Their structures were elucidated by physicochemical properties and spectral analyses. Results Twelve compounds were isolated from water extracts of the berry of P. ginseng. They were identified as benzoic acid (Ⅰ), isoginsenoside-Rh3 (Ⅱ), ginsenoside-Rh2 (Ⅲ), ginsenoside-Rh1 (Ⅳ), ginsenoside-Rg1 (Ⅴ), ginsenoside-Re (Ⅵ), ginsenoside-Rd (Ⅶ), ginsenoside-Rc (Ⅷ), ginsenoside-Rb2 (Ⅸ), ginsenoside-Rb1 (Ⅹ), β-sitosterol (Ⅺ), and 20-O-β-D-glucopyranosyl-20 (S)-protopanaxadiol named as compound K (ⅩⅡ). Conclusion The compound K is a new natural product.
