|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. 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.

|Antitumor Triterpenes from Scorzonera mongolica Maxim[Reference: WebLink]|
|To study the anti-tumor active constituents of Scorzonera mongolica Maxim..METHODS The chemical components were isolated by silica gel H,Sephadex LH-20 column chromatography and semi-preparative HPLC.Structures were elucidated on the basis of physicochemical properities and spectral data.The anti-tumor experiment in vitro,the MTT and SRB methods were used to screen constituents of S.mongolica Maxim..RESULTS 15 Triterpenes were isolated and identified as lupeol (1),betulin (2),betulinic acid (3),lupeo acetate (4),23Z-3β-acetoxyeupha-7,23-diene-25-ol (5),Dammaradienyl acetate (6),pulcherryl acetate (7),taraxasterol (8),taraxasteryl acetate (9),ψ-taraxasterol (10),ψ-taraxasteryl acetate (11),α-amyrin acetate (12),dammar-24-ene-3,20-diol,3β-tetradecanoate (13),butyrospermyl acetate (14) and multiflorenyl acetate (15),respectively.CONCLUSION Compound 1-15 were obtained from the plant for the first time and compound 2,3,5-15 were obtained from the genus Scorzonera for the first time.Compound 1-5 demonstrated significant inhibitory effects on A-549 cancer cells and compound 14 showed also strong cytotoxity against Bel-7402 cancer cells at the concentration of 50 mg·L-1.|
