Butyrospermol
Butyrospermol acetate exhibits inhibitory effect on skin tumor promotion in an in vivo two-stage carcinogenesis test using 7,12-dimethylbenz [a] anthracene (DMBA) as an initiator and TPA as a promoter, the exceptionally high levels of triterpenes in shea fat, indicates that shea nuts and shea fat (shea butter) constitute a significant source of anti-inflammatory and anti-tumor promoting compounds.

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.
Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Anti-HBV constituents from Euphorbia fischeriana.[Pubmed:
21355270]
To investigate the anti-HBV constituents in the roots of Euphorbia fischeriana.
METHODS AND RESULTS:
The compounds were isolated by various chromatographic methods and identified by spectroscopic analysis. Some compounds were tested for the anti-HBV activity. Eleven compounds were isolated and identified as tirucalla-5,24-dien-3-ol (1), 24-methyltirucalla-5, 24-dien-3-ol (2), euphol (3), Butyrospermol (4), 24-methylenecycloartenol (5), cycloartenol (6), jolkinolid E (7) helioscopinolide A (8), isoscopoletion (9), dephnoretin (10), and 3, 3'-di-O-methylellagic acid 4'-O-beta-D-xylopyranoside (11).
CONCLUSIONS:
Compounds 1, 2 and 10 were isolated from the genus Euphorbia for the first time. Compounds 3, 4 and 11 were isolated from this species for the first time. Compounds 1, 8, 9 and 11 showed weak anti-HBsAg and anti-HBeAg activity, while compound 10 showed weak anti-HBsAg activity.

Triterpene alcohol and fatty acid composition of shea nuts from seven African countries.[Pubmed:
20513968]
The content and composition of triterpene alcohol fractions of the non-saponifiable lipids (NSL) along with the fatty acid composition of the kernel fats (n-hexane extracts) of the shea tree (Vitellaria paradoxa; Sapotaceae) were determined for 36 samples from seven sub-Saharan countries: Cote d' Ivoire, Ghana, Nigeria, Cameroun, Chad, Sudan, and Uganda.
METHODS AND RESULTS:
The fat content of the kernels, proportion of NSL in the fats, and triterpene alcohols in the NSL are in the range of 30-54, 2-12, and 22-72%, respectively. The triterpene alcohol fractions contained alpha-amyrin (1), beta-amyrin (2), lupeol (3), and Butyrospermol (4) as the major constituents along with minor or trace amounts of psi-taraxasterol (5), taraxasterol (6), parkeol (7), 24-methylene-24-dihydroparkeol (8), 24-methylenecycloartanol (9), dammaradienol (10), and 24-methylenedammarenol (11). Fatty acid composition is dominated by stearic (28-56%) and oleic (34-61%) acids. Shea butters from West African provenances contained in general higher levels of triterpene alcohols and stearic acid than those from East African provenances.
CONCLUSIONS:
Both stearic acid and total triterpene alcohol contents were significantly correlated to the latitude and elevation of the source population, indicating that higher levels of these compounds are found at higher ambient temperatures.
