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.

Dammarane-type Saponins from Panax japonicus and their neurite outgrowth activity in SK-N-SH cells.[Pubmed: 12350149
METHODS AND RESULTS:
Four new dammarane-type saponins (1-4), named yesanchinosides G-J, together with nine ginsenosides (5-13) were isolated from Ye-Sanchi, the underground part of Panax japonicus collected in the south of Yunnan Province, China. Their structures were elucidated on the basis of spectroscopic and chemical methods.
Ginsenosides Rb(1) and Rb(3) and notoginsenosides R(4) (6) and Notoginsenoside Fa (7) showed significant neurite outgrowth enhancing activities in human neuroblastoma SK-N-SH cells.
