【 摘 要 】

Abstract The search for chemopreventive/chemoprotective compounds in marine organism has been extensively reported; however, the presence of these compounds in octopus has been incipiently explored. In this research, the antimutagenic, antiproliferative, and antioxidant potential of three crude extracts (methanolic, acetonic, and hexanic) from Paroctopus limaculatus was investigated. Antimutagenic activity against aflatoxin B1 (AFB1) was evaluated through the Ames test using Salmonella typhimurium tester strains TA98 and 100. Antiproliferative activity was assessed using the standard MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide) assay on M12.C3.F6 murine cell line. Antioxidant activity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) methods. Hexanic extract showed the highest antimutagenic and antiproliverative activities inhibiting 80 and 43% of mutagenicity induced by AFB1 for TA98 and TA100, respectively, and showing a high antiproliferative activity at 200 and 100 µg/mL. However, when the antioxidant activity was evaluated at a concentration of 50 mg/mL, the methanolic fraction exerted inhibition of 98 and 96 % ABTS and DPPH radicals, respectively. RP-HPLC and 1H-RMN analyses suggested the presence of double bonds with extended conjugation and oxygenated compounds such as alcohols, esters, ethers or ketones. These results suggested that hexanic and methanolic extract form octopus contained compounds with chemoprotective and antioxidant properties.
