Fine Chemicals, 2004, 21(7):525-528. | Antioxidation Activities of Natural Components from Dalbergia odorifera T.Chen.[Reference: WebLink] | METHODS AND RESULTS: The antioxidation activities of natural components extracted from Dalbergia odorifera T.Chen on lard and ascidian oil were investigated by OSI.Dalbergia odorifera T.Chen was extracted with 95% ethanol,and the extract was then extracted by petroleum ether,CHCl_3,EtOAc and BuOH successively.The residue of EtOAc had very good antioxidation activity.Eight components were isolated from it,i.e.,2,4-dihydroxy-5-methoxybenzophenone(Ⅰ),2′,3′,7-trihydroxy-4-methoxyisoflavone(Ⅱ),3'-Methoxydaidzin(Ⅲ),4′,5,7-trihydroxy-3-methoxyflavone(Ⅳ),vestitol(Ⅴ),medicarpin(Ⅵ),2-propenyl hexanoate(Ⅶ) and ethyl hexadecanoate(Ⅷ).
CONCLUSIONS:
The results showed that components Ⅰ,Ⅲ,Ⅴ and Ⅵ had antioxidation activity and components Ⅱ and Ⅳ had strong antioxidant activities both on lard and ascidian oil at 0.02% and 0.04% levels. |
