Abstract: The biological activities of extracts from the three medicinal flowers including Mimusops elegi (Sapotaceae), Millingtonia hortensis (Bignoniaceae) and Gardenia jasminoides (Rubiaceae) prepared by the two non-heated processes were investigated. The biological activities of the extracts by the supercritical carbon dioxide fluid (scCO2) with the co-solvent (ethanol) at 4, 20, 33 and 50% (w/v) were compared with the extracts prepared by hexane maceration. All extracts by scCO2 gave higher free radical scavenging and skin fibroblast proliferation activities than those by the hexane maceration. The scCO2 extracts of M. elengi, M. hortensis and G. jasminoides prepared with 20, 33 and 33 % (w/v) ethanol as a co-solvent which showed the high percentage yields and free radical scavenging activity, were selected to investigate for MMP-2 inhibition activity (43.85 ± 9.61%), high percentage yield (8.78 ± 1.27% w/w), high free radical scavenging activity (SC50 at 5.14 ± 0.32 mg/ml) and low toxicity on human skin fibroblast (% cell growth of 68.48 ± 5.95 %). The high MMP-2 inhibition activity of this extract indicated its beneficial to be developed as anti-aging cosmetics. |
