摘要

The evaluation of antioxidant property, total phenolic compounds and pigment content of 8 medicinal plants including:?Gynostemma pentaphyllum?Thunb.,?Camellia sinensisKtze.,?Cymbopogon citratus?Stapf.,?Centella asiatica?(L.) Urban.,?Andrographis paniculata?(Burm.)?Wall. ex Nees,?Thunbergia laurifolia?Lindl.,?Murdania loriformis(Hassk.) Rolla Rao et Kammathy and?Acanthus ebracteatus?Vahl., was performed using 95% methanol as a solvent.?C. sinensis?methanolic extract showed the highest antioxidant activity with 0.34 μg/ml IC50?followed by the extract of?C. asiatica?and?G. pentaphyllum,?respectively. The extract of?A. paniculata?had the highest chlorophyll?ayield.?C. sinensis?extract had the highest chlorophyll?b?content. While, the carotenoid constituent can be determined only in?G. pentaphyllum?methanolic extract. However, the highest level of total pigment was in?C. sinensis?extract. Correlation analysis found a statistically significant relationship with an exponential pattern between the amount of total phenolic compounds and?the?antioxidant property at correlation level?was0.9687. On the other hand, the total pigment yield did not have a correlation with antioxidant activity.
