2-Oxopomolic acid
2-Oxopomolic acid shows cytotoxic activity, it shows a significant decrease in intracellular melanin content in B16-F10 cells, and in culture media melanin. 2-Oxopomolic acid shows radical-scavenging activities similar to that of the reference antioxidant alpha-tocopherol (vitamin E).

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.

Cytotoxic triterpene acids from the Peruvian medicinal plant Polylepis racemosa.[Pubmed:
10909276]
METHODS AND RESULTS:
Cytotoxicity-guided fractionation of the bark and stem extract of Polylepis racemosa led to the identification of ursolic acid, pomolic acid, 3-O-acetylpomolic acid, and 2-Oxopomolic acid. Pomolic acid was the most cytotoxic component, and was specific for M-14 melanoma and ME180 cervical carcinoma, with GI50 values of 6.9 and 8.3 micrograms/mL respectively.

Radical-scavenging activities of new hydroxylated ursane triterpenes from cv. Annurca apples.[Pubmed:
17193186]
METHODS AND RESULTS:
Two new ursolic acid triterpene derivatives, compounds 2 and 3, have been isolated from cv. Annurca apple fruit, a high-quality apple variety widely cultivated in southern Italy, together with the known 2-Oxopomolic acid (1). The new compounds were identified by means of different spectroscopic techniques as 3-epi-2-Oxopomolic acid (= (3alpha)-3,19-dihydroxy-2-oxours-12-en-28-oic acid; 2) and (1alpha)-1-hydroxy-3-oxours-12-en-28-oic acid (3). Compounds 1-3 were tested for their radical-scavenging activities with the aid of a 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay (Fig. 2).
CONCLUSIONS:
All three constituents showed activities similar to that of the reference antioxidant alpha-tocopherol (vitamin E).

Triterpenoids from Fragaria ananassa calyx and their inhibitory effects on melanogenesis in B16-F10 mouse melanoma cells.[Pubmed:
23772756 ]
METHODS AND RESULTS:
Column chromatographic technology was applied to isolate six purified ursane triterpenoids from the calyx of Fragaria ananassa and they were identified on the basis of spectroscopic methods to be ursolic acid (1), pomolic acid (2), 2-Oxopomolic acid (3), 3-O-acetyl pomolic acid (4), fupenzic acid (5) and euscaphic acid (6).
This is the first study in which these compounds have been isolated from the calyx of F. ananassa.
CONCLUSIONS:
Compared to a well-known inhibitor, α-arbutin, compounds 2-6 showed a significant decrease in intracellular melanin content in B16-F10 cells, and in culture media melanin.
