Total panax notoginsenosides (TPNS) are the main active ingredients in San-Chi, the root of(Burk) F.H. Chen, which belongs to the Araliaceae family and has been used in traditional Chinese medicine to treat atherosclerosis;TPNS can prevent atherosclerosis by lowering serum lipid levels and regulating vascular CD40 and MMP-9 expression, TPNS may have implications for clinical treatment of atherosclerosis vascular disease.
Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Two new dammarane triterpene glycosides from the rhizomes of Panax notoginseng.[Pubmed:
18985496]
METHODS AND RESULTS:
Two new dammarane triterpene glycosides named notoginsenosides Rw 1 (1) and Rw 2 (2) were isolated from the rhizomes of Panax notoginseng, together with 20 known compounds including protopanaxadiol (3), protopanaxatriol (4), ginsenosides Rb1 (5), Rd (6), Re (7), Rg1 (8), Rg2 (9), 20-(S)-Rg3 (10), 20-(R)-Rg(3) (11), Rh1 (12), Rh4 (13), Rf (14), 20-O-glucopyranosyl Rf (15), notoginsenoside R1 (16), R2 (17), Notoginsenoside T5 (18), S (19), T (20), and Fa (21), and koryoginsenoside R1 (22). Based on FABMS, HRFABMS, IR, (1)H, 13C, and 2D-NMR (HSQC, HMBC, and COSY) spectral data, the structures of the new compounds were elucidated as 6-O-beta-d-xylopyranosyl-20-O-beta-d-xylopyranosyl-(1 --> 6)-beta-d-glucopyranosyldammar-24-ene-3beta,6alpha,12beta,20(S)tetraol (1) and 6-O-beta-d-xylopyranosyl-(1 --> 2)-beta-d-glucopyranosyldammar-22-ene-(trans)-3beta,6alpha,12beta,20(S), 25-pentaol (2).
CONCLUSIONS:
Compounds 3, 4, 13, and 22 were isolated from P. notoginseng for the first time.
