Trametenolic acid | CAS:24160-36-9 | Manufacturer ChemFaces

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.

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 and Acceleratory Effects of Inonotus obliquus on Tyrosinase Activity and Melanin Formation in B16 Melanoma Cells.[Pubmed: 25197307]

METHODS AND RESULTS:
In cells testing, betulin and Trametenolic acid decreased tyrosinase activity and melanin content, while inotodiol and lanosterol significantly increased tyrosinase activity and melanin content, showing an AC⁡50 of 9.74 and 8.43 μM, respectively. Nicotinie acid, 3β,22,25-trihydroxy-lanosta-8-ene, had a little or no effect on tyrosinase. Betulin exhibited a mode of noncompetitive inhibition with a K I = K IS of 0.4 μM on tyrosinase activity showing an IC50 of 5.13 μM and being more effective than kojic acid (6.43 μM), and Trametenolic acid exhibited a mode of mixed inhibition with a K I of 0.9 μM, K IS of 0.5 μM, and an IC50 of 7.25 μM.
CONCLUSIONS:
We proposed betulin and Trametenolic acid as a new candidate of potent tyrosinase inhibitors and inotodiol and lanosterol as accelerators that could be used as therapeutic agent.

Rapid isolation and purification of inotodiol and trametenolic acid from Inonotus obliquus by high-speed counter-current chromatography with evaporative light scatting detection.[Pubmed: 21433158]

Inotodiol and Trametenolic acid are considered to be the main bioactive compounds of the fruiting body of the mushroom. These compounds show various biological activities, including anti-tumour, anti-viral, hypoglycaemic, anti-oxidant and cyto-protective. However, effective methods for isolating and purifying inotodiol and Trametenolic acid from the fruiting body of Inonotus obliquus are not currently available. To develop a suitable preparative method in order to isolate inotodiol and Trametenolic acid from a complex Inonotus obliquus extract by preparative high-speed counter-current chromatography (HSCCC).
CONCLUSIONS:
Inotodiol and Trametenolic acid were rapidly isolated and purified from the chloroform extract of Inonotus obliquus (Fr.) by HSCCC with evaporative light scatting detection (ELSD).The target compounds were finally isolated and purified with a solvent system of hexane:ethyl acetate:methanol:water (1:0.4:1:0.4, v/v/v/v). In a single operation, 100 mg of the I. obliquus extracts yielded 13.0 mg of inotodiol and 7.0 mg of Trametenolic acid. The entire separation and purification process took less than 5 h. The purities of obtained inotodiol and Trametenolic acid were 97.51 and 94.04%, respectively.
CONCLUSIONS:
HSCCC-ELSD was an efficient and rapid method for the separation and purification of inotodiol and Trametenolic acid from I. obliquus.
