Dimeric proanthocyanidins from the roots of Ephedra sinica[Pubmed: 18975262]
Two new dimeric proanthocyanidins, ephedrannin B ( 2) and Mahuannin E ( 4), along with two known congeners, ephedrannin A ( 1) and mahuannin D ( 3), were isolated from the roots of Ephedra sinica Stapf. Based on NMR, MS, and CD analysis, the structures of the new compounds were deduced to be 5,7,4'-trihydroxyflavan-[4(alpha)-->8,2(alpha)-->O-->7]-kaempferol ( 2) and 5,7,4'-trihydroxyflavan-[4(beta)-->8,2(beta)-->O-->7]- EPI-afzelechin ( 4). The compounds 1 - 4 were evaluated for cytotoxicity against three tumor cell lines (SGC-7901, HepG2, and HeLa), and 2 was found to be significantly active.
Mahuannin E Description
Source: The herbs of Ephedra spp.
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: 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.
