|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.

|Studies on the liposoluble components from tuber of Ophiopogon japonicus.[Reference: WebLink]|
|The compounds were isolated by column chromatography with silica gel and Sephadex LH-20 and the structures were elucidated by spectras' analysis. Sixteen compounds were obtained as 7 homoisoflavones, 2 anthraquinones, 3 phenolic acids, 2 terpenes and 2 fatty acids. Their structures were identified as methylophiopogonanone A(I), methylophiopogonanone B(II), methylophiopogonone A(III), Methylophiopogonone B(IV), 2'-hydroxy-methylophiopogonone A(V), 6-aldehycto-isoophiopogo-nanone A(VI), 5,7-dihyelroxy-8-methoxy-6-methyl-3-(2'-hydroxy-4'-methoxybenzyl) chroman-4-one(VII), chrysophenol(VIII), emodin(IX), vanillic acid(X), P-hydroxy benzaldenhyde (XI), P-trans-coumarinic acid(XII), l-borneol-#beta#-D-glucopyranoside (XIII), oleanolia acid(XIV), azelaic acid (XV) and n-tricosanoic acid(XVI). The compound IV, VIII--XII and XIV--XVI were isolated from O. japonicus and the genus Ophiopogon for the first time, respectively. The types of anthraquinone, phenolic acid and triterpene were firstly obtained from the genus.|
