|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.

|Binding of flavonoids from Sophora flavescens to the rat uterine estrogen receptor.[Pubmed: 16320211]|
|Prenylflavonoids and lavandulylflavonoids were isolated from the roots of Sophora flavescens Aiton (Fabaceae). The ability of 8-prenylkaempferol (1), Kushenol X (2), norkurarinone (3), leachianone A (4), kushenol C (5), maackiain (6) and a root-extract of S. flavescens to displace 17beta-estradiol (E2) from rat uterine estrogen receptor (ER) was determined. Relative binding affinities (RBA) of prenylated flavonoids were weak with RBA values between 0.004 and 0.072. A lavandulyl or prenyl group at the position 8 enhanced binding to rat uterine ER.|

|Lavandulyl flavonoids with sodium-dependent glucose cotransporter 2 inhibitory activity from Sophora flavescens[Reference: WebLink]|
|To discover new bioactive Sodium-dependent glucose cotransporter 2(SGLT2)inhibitors from the traditional Chinese medicine"Ku Shen"(roots of Sophora flavescens),the bioassay-guided purification of an active ethyl acetate fraction was performed.Sixteen lavandulyl flavonoids were isolated and their structures were elucidated as kushenol H(1),kushenol K(2),kurarinol(3),kushenol Y(4),kushenol P(5),norkurarinone(6),kushenol I(7),kushenol N(8),(-)-kurarinone(9),Kushenol X(10),neokurarinol(11),kushenol C(12),sophoraflavanone G(13),leachianone A(14),kuraridine(15)and kushenol A(16).All isolated compounds exhibited inhibitory activity against SGLT2.Among them,the two main constituents of the active EtOAc fraction,(-)-kurarinone(9)and sophoraflavanone G(13)showed the most potential inhibitory activity against SGLT2with the IC50values of 2.24μmol/L and 1.45μmol/L,respectively.|

|Simultaneous Determination of Nine Major Flavonoids in Sophora flavescens by RP-LC[Reference: WebLink]|
|A liquid chromatographic method was applied to determine trifolirhizin, kushenol K, kushenol L, kushenol N, Kushenol X, kurarinone, norkurarinone, isokurarinone and kushenol A in the roots of Sophora flavescens, namely Kushen in China. The samples were separated on a YMC-C18 column (250 × 4.6 mm, 5 μm) with a gradient of methanol and 0.3% aqueous acetic acid (v/v) at a flow rate of 0.8 mL min−1 and detected at 295 nm. The complete separation was achieved within 45 min for the nine major flavonoids. All calibration curves expressed good linearity (r2 > 0.999) within the test range. The recovery of this method was 92.3–106.9%. The assay was successfully applied to the quantification of nine flavonoids in 26 samples of Kushen. The results indicated that this developed LC assay could be readily utilized as a quality control method for the Chinese herb medicine Kushen.|
