Embodiment 1
[0023] Preparation of 20(R)-notoginsenoside Ft1:
[0024] The stems and leaves of notoginseng are extracted with 10 times the amount of 1% HCl solution, extracted twice, each time for 2 hours, the filtrates are combined, the pH is adjusted to 7 with 3% NaOH solution, concentrated and dried to obtain a dry paste. Dry paste 100g, mix sample with silica gel (200-300 mesh) and carry out silica gel column chromatography, use chloroform: methanol: water (8:2:0.2) as eluent, thin layer chromatography checks and merges the same color point Fractions, Fr1-5 fractions were obtained. Fr4 (5g) is carried out repeated silica gel column chromatography with chloroform: methanol: water (8:2:0.2) as eluent, and reverse phase silica gel RP-18 column chromatography (methanol: water / 7:3), obtains 20 (R)-Notoginsenoside Ft1 (0.12 g).
