    3-O-Acetyl-16 alpha-hydroxytrametenolic acid Description
    Source: The sclerotium of Poria cocos(Schw.)Wolf
    Biological Activity or Inhibitors: 1. 3-O-Acetyl-16 alpha -hydroxytrametenolic acid has inhibitory activities against AAPH-induced hemolysis of red blood cells.
    2. 3-O-Acetyl-16 alpha-hydroxytrametenolic acid shows a strong inhibitory activity against 12-O-tetradecanoylphorbol-13-acetate-induced inflammation in mice.
    3. At 0.2 mumol/mouse, 3-O-Acetyl-16 alpha-hydroxytrametenolic acid markedly inhibited the promoting effect of 12-O-tetradecanoylphorbol-13-acetate (1 microgram/mouse) on skin tumor formation following initiation with 7,12-dimethylbenz[a]anthracene (50 micrograms/mouse).
    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.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: 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.

    Inhibitory effects of lanostane-type triterpene acids, the components of Poria cocos, on tumor promotion by 12-O-tetradecanoylphorbol-13-acetate in two-stage carcinogenesis in mouse skin.[Pubmed: 8784472]
    Pachymic acid, 3-O-Acetyl-16 alpha-hydroxytrametenolic acid, and poricoic acid B had been isolated from the sclerotium of Poria cocos Wolf. These compounds showed a strong inhibitory activity against 12-O-tetradecanoylphorbol-13-acetate-induced inflammation in mice. At 0.2 mumol/mouse, these compounds markedly inhibited the promoting effect of 12-O-tetradecanoylphorbol-13-acetate (1 microgram/mouse) on skin tumor formation following initiation with 7,12-dimethylbenz[a]anthracene (50 micrograms/mouse).

    Inhibitory effects of triterpenes isolated from Hoelen on free radical-induced lysis of red blood cells.[Pubmed: 12601680 ]
    Hoelen, sclederma of Poria cocos Wolf, has long been used as a sedative and diuretic in traditional medicine. Formerly, we demonstrated that Hoelen in vitro protects red blood cells from AAPH-induced hemolysis. In this study, tests were carried out to identify the main ingredient of Hoelen that has the scavenging effect on free-radicals. Triterpene carboxylic acids isolated from the methanol extract of Hoelen, i.e. pachymic acid, polyporenic acid, 3-epidehydrotumulosic acid, 3beta-hydroxylanosta-7,9(11), 24-trien-21-oic acid and 3-O-Acetyl-16 alpha-hydroxytrametenolic acid, were found to have inhibitory activities against AAPH-induced lysis of red blood cells.
