General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

New taxane diterpenoids from the roots of Taxus mairei.[Pubmed: 8991951 ]

J Nat Prod. 1996 Feb;59(2):173-6.


METHODS AND RESULTS:
Two new taxoids, taxumairol A (1) and Taxumairol B (2), have been isolated from extracts of the roots of Formosan Taxus mairei (Lemee & Levl.) S. Y. Hu. The structures of 1 and 2 were identified as 5 alpha, 7 beta, 9 alpha, 10 beta, 13 alpha-pentaacetoxy-20-(benzoyloxy)- 2 alpha, 4 alpha-dihydroxytax-11-ene and 2 alpha, 5 alpha, 10 beta,-13 alpha-tetraacetoxy-1 beta, 7 beta, 9 alpha-trihydroxy-4 beta,20-epoxytax-11-ene, primarily on the basis of 1D- and 2D-NMR techniques including DEPT, COSY, and HMBC experiments, as well as chemical correlation with known compounds.
CONCLUSIONS:
Taxumairol A (1) exhibited significant cytotoxicities against murine P-388 and human KB-16, A-549, and HT-29 tumor cell lines.

Chemical constituents from seeds of Taxus yunnanensis.[Reference: WebLink]

To study the chemical constituents from the seeds of Taxus yunnanensis.
METHODS AND RESULTS:
The chemical constituents in the seeds of T. yunnanensis were isolated by chromatography and identified by a comprehensive analysis on the spectral data. Twelve taxanes were isolated from the seeds of T. yunnanensis and identified as 7-epi-10-deacetyltaxol (1), 2-deacetoxytaxuspine C (2), 9α-hydroxy-2α, 7α, 10β-triacetoxy-5α-cinnamoyloxy-3, 11-cyclotaxa-4(20)-en-13-one (3), 2α-acetoxy-5α-cinnamoyloxy-9α, 10β-dihydroxy-taxa-4 (20), 11-diene-13-one (4), dantaxusin C (5), taxezopidine H (6), 9-deacetyltaxinine A (7), 5α-decinnamoyltaxagifine (8), Taxumairol B (9), 2α, 5α, 13α-trihydroxy-7β, 9α, 10β-triacetoxy-taxa-4(20), 11-diene (10), 7, 9, 10, 13-tetra-O-deacetylabeobaccatin VI (11), and taxacustin (12).
CONCLUSIONS:
Compounds 2, 3, and 7-12 are isolated from T. yunnanensis for the first time.
