Evaluate the total polyphenol, flavonoid and antioxidant activity of dinh lang roots (Polyscias fruticosa (L.) Harm) naturalli grown and cultivated by aeroponic methods
Abstract
Polyscias fruticosa (L.) Harms is a precious medicinal plant that has been used for a long time in Vietnam. Previous studies have shown that P.fruticosa has the same pharmacological effects as Ginseng. However, because the cost is cheaper and it is easier to grow than Ginseng. , Nowadays, more and more new methods are used to grow P.fruticosa, like aeroponics. This research aims to evaluate the total polyphenol, flavonoids content and antioxydant activities of P.fruticosa using UV-VIS spectrophotometry. The results indicated that the highest total polyphenol content was 125.37µg GAE/mg extract and flavonoid content was 86.13μg QE/mg for dry ethanol extract in P.fruticosa roots grown using aeroponics technology. The IC50 value of this extract using DPPH and ABTS methods were 73.54 and 35.33µg/ml, respectively, which showed high potential antioxydant activity. According to the results of present investigation, the plant showed significant antioxydant activity that can be used for the treatment of various diseases.
