||The herbs of Crepis crocea.
|Biological Activity or Inhibitors:
||DMSO, Pyridine, Methanol, Ethanol, etc.
||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.

|Chemical constituents from Crepis crocea.[Pubmed: 26975105]|
|Thirteen compounds were isolated from the ethyl acetate fraction of Crepis crocea by column chromatographies on silica gel, Sephadex LH-20 and semi-preparative HPLC. The structures were elucidated on the basis of spectral analysis as tectorone I (1), 8β- (2-methyl- 2-hydroxy-3-oxobutanoyloxy) -glucozaluzanin C (2), Tectoroside (3), luteolin-7-O-glucoside (4), cosmosiin (5), esculetin (6), 3,4-dihydroxybenzaldehyde (7), trans-4-hydroxycinnamic acid (8), Caffeic acid (9), methyl p-hydroxyphenyllactate (10), ethylp- hydroxyphenyllactate (11), cis-3,4-dihydroxy-β-ionion (12). All the compounds, except for compounds 4 and 9, were isolated from this plant for the first time, and tectorone I (1) is a new natural product.
