|Source:||The barks of Taxus chinensis var. mairei.|
|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.

|Chemical constituents of bark of Taxus chinensis var. mairei.[Pubmed: 25095344]|
|To study the chemical constituents in the bark of Taxus chinensis var. mairei collected from southeast of China. METHODS: Chemical constituents were isolated and purified by column chromatography, Prep-TLC, and preparative HPLC. The structures were identified on the basis of 1D-and 2D-NMR spectral analysis. RESULTS: Twelve taxane diterpenoids were isolated from the bark of Taxus chinensis var. mairei grown in southeast of China. They were identified as: taxagifine (1), Decinnamoyltaxagifine (2), 19-debenzoyl-19-acetyltaxinine M(3), 9-dihydro-13-acetyl-baccatin III (4), 7, 9-dideacetylbaccatin IV (5), 1,3-dihydro-taxinine (6), taxumairol C (7), taxezopidine J (8), 7-xylosyl-10-deacetyl-taxol A (9),10-deacetyltaxol (10), taxicin II (11), and 2alpha, 7beta, 10beta-triacetoxy-5alpha, 13alpha-dihydroxy-2 (3 --> 20) abeotaxa-4 (20), 11-dien-9-one (12). CONCLUSION: Compounds 1, 2, 4 - 6, 8, 9, 11 and 12 are obtained from this plant for the first time. Compound 7 is obtained from the bark of Taxus chinensis var. mairei for the first time.|
