acid red 14

Carmoisine (Azo Rubine) is a food dye Azorubine and is used for the purposes where food is heat-treated after fermentation.

9,13β-Epidioxy-8(14)-abieten-18-oic acid has anti-inflammatory activities, it exhibits moderate activities on NO levels in LPS-stimulated murine microglia BV2 cells, with IC50 values of 57.3 ± 0.2 uM. It is also a potential antitumor-promoting diterpenoid, it shows potent inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by the tumor promoter 12-O-tetradecanoylphorbol 13-acetate. 9 α ,13 β -Epidioxyabeit-8(14)en-18-oic acid may contribute to the growth inhibitory effect of the pine needles and may play an important role in the allelopathy of red pine.

Polyporusterone B ((1R,2R,4S,5R,7R,11R,14S,15R)-14-[(2R,3R)-2,3-dihydroxy-6-methyl-5-methylideneheptan-2-yl]-4,5,11-trihydroxy-2,15-dimethyltetracyclo[8.7.0.02,?.011,1?]heptadec-9-en-8-one) is a triterpene carboxylic acid isolated from Polyporus umbellatus Fries known as pentahydroxy bile acids, alcohols, and derivatives. Polyporusterone B Polyporusterone B has an inhibitory effect on free radical-induced lysis of red blood cells (hemolysis).
