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.

Two secopregnane-type steroidal glycosides from Cynanchum stauntonii (Decne.) Schltr.ex Levl.[Reference:
WebLink]
METHODS AND RESULTS:
Two new steroid glycosides, Stauntosaponin A (1) and stauntosaponin B (2), were isolated from Cynanchum stauntonii (Decne.) Schltr.ex Levl. (Asclepiadaceae) together with five known compounds, anhydrohirundigenin monothevetoside, glaucogenin C mono-d-thevetoside, hirundoside A, cynatratoside A, and glaucogenin C. Stauntosaponins A and B were formulated as 3-O-β-d-oleandropyranosyl-14, 16: 15, 20: 18, 20-triepoxy-14, 15-secopregn-4, 6, 8(14)-triene (1) and 3-O-β-d-thevetopyranosyl-14, 16: 15, 20: 18, 20-triepoxy-14, 15-secopregn-4, 6, 8(14)-triene (2).
CONCLUSIONS:
Compounds 1 and 2 showed moderate inhibitory activities against Na+/K+-ATPase with IC50 values of 21 and 29 μM, respectively, whereas ouabain as a positive control displayed an IC50 value of 3.5 μM.
