Embodiment 1
[0050] Example 1 Preparation of Panaxadiol Saponin Fraction-A (PDSF-A) from Radix Ginseng
[0051] 1. Isolation and Purification of Panaxadiol Saponin Fraction-A (PDSF-A) :
[0052] Ginseng rhizome medicinal material (8000 grams, sample-A, five kinds of ginseng diol saponins Rb contained therein 1 , Rc, Rb 2 , Rb 3 and Rd content and their total content are shown in Table 5) after pulverizing into a coarse powder, use 50% ethanol aqueous solution to percolate and extract until the extract is colorless, combine the percolate to recover ethanol under reduced pressure and freeze-dry to obtain the extract (678.6 gram). The medicinal extract was dissolved in 3000 milliliters of 45% ethanol aqueous solution, and the sample liquid was separated by macroporous adsorption resin (Diaion HP-20, 6000 grams) column chromatography, and first eluted with 45% ethanol aqueous solution until the eluent had no obvious saponin reaction, and then eluted with 70% ethanol aqueous solution u...

[0075] Example 2 Preparation of Panaxadiol Saponin Component-B (PDSF-B) from American Ginseng Rhizome
[0076] With American ginseng rhizome medicinal material (7000 grams, sample-B, five kinds of ginseng diol saponins Rb contained therein 1 , Rc, Rb 2 , Rb 3 and the content of Rd and their total content are shown in Table 5, and its HPLC collection is shown in Figure 1-3 ), adopt the same method of embodiment one to prepare the ginseng diol saponin component - B (PDSF-B, 101.3 g). HPLC analysis shows: PDSF-B also contains ginsenoside Rb 1 , Rc, Rb 2 , Rb 3 and Rd five kinds of ginsenosides, the total content of these five kinds of saponins is 91.60%, of which ginsenoside Rb 1 The highest content, followed by Rb 3 , Rd, Rb 2 and Rc; and Rb in Panaxadiol Saponin Fraction-B 1 / Rc / Rb 2 / Rb 3 / Rd content ratio and Rb in American ginseng rhizome (sample-B) 1 / Rc / Rb 2 / Rb 3 The content ratio of / Rd is basically the same (Table 5).
Embodiment 3
[0077] Example 3 Preparation of Panaxadiol Saponin Component-C ( PDSF -C)
[0078] Purchased commodity ginseng rhizome total saponins (sample-C 1 , its total saponin content ≥ 80%) and American ginseng stem and leaf total saponin (sample-C 2 , its total saponin content ≥ 80%) show through HPLC analysis, five kinds of ginseng diol saponins contained in these two kinds of total ginsenoside products have their own characteristics respectively, namely: Sample-C 1 Both contain ginsenoside Rb 1 , Rc, Rb 2 , Rb 3 and Rd, but Rb 3 The content is very low (see attached diagram 2-1 and Table 5); Sample-C 2 Contains mainly Rb 3 and Rd, and Rb 1 , Rc and Rb 2 The content is very low (see attached Figure 2-2 and Table 5). This implementation comprehensively utilizes these two samples (sample-C 1 and sample-C 2 ) as this raw material to prepare the ginsengdiol saponin active component of the present invention, especially to obtain the total content of five kinds of ginseng...
