Abstract

ABSTRACT Excessive Reactive Oxygen Species (ROS) can cause hypertension. Prevention of the risk of hypertension is consume an antioxidant. Noni (Morinda citrifolia L). is a plant that empirically proven to lower blood pressure and has antioxidant activity. Antihypertensive activity of noni leaves is influenced by phenolic and flavonoid compounds. The extraction method affects the levels of compound in extracts. The aims of study is determine the effect of the extraction method on the total phenolic level, total flavonoid level and antioxidant activity of noni leaf extract. The extraction methods are maceration, Microwave Assisted Extraction and Soxhlet. The results showed that the different extraction methods affected the total phenol level, total flavonoid level and antioxidant activity of the noni leaf extract. The Soxlet method provides the highest total phenolic level, total flavonoid level and antioxidant activity than other extraction methods. Keywords: Noni leaf extract, extraction method, total phenolic level, total flavonoid level and antioxidant activity

Abstract

The flavonoid compound in Noni leaves (Morinda citrifolia) are efficacious as free radical scavengers. This research aimed to know the influence of the ratio of materials and a solvent (M:S=1:10; M:S=1:15; M:S=1:20) on the flavonoid content and free radical scavenging activity of extract of noni leaves. Extraction was carried out using the Microwave Assisted Extraction method and the free radical scavenging activity were determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH). The results showed that the material-solvent ratio had a significant effect on the yield, total flavonoid content, and free radical scavenging activity. The material to solvent ratio 1: 20 resulted in the highest yield, total flavonoid content, and free radical scavenging activity compared to other solvent-solvent ratios.
