Study on phenolic content, flavonoid content, and antioxidant capacity of extracts from Lansium parasiticum (Osbeck)

<p><em>Lansium parasiticum</em> <em>(Osbeck)</em> or its synonym <em>Epicharis parasitica</em> is from <em>the Meliaceae family and has traditionally been used for various</em> medical applications. This study aimed to determine the total phenolic content, flavonoid antioxidant activity of different duku extracts. A four solvents, 50% ethanol, 100% aqueous, acetone, chloroform, were extract flesh. The content was determined using Folin-Ciocaltealuminumminium chloride colorimetric method. DPPH ABTS method evaluated activity. result showed that ethanol presented highest extraction yield, 10.81% ± 0.004. It also revealed aqueous exhibited amount 152.910 mg GAE/100 g 22.143, 1669.723 370.091 QE/100 g, 68.51 % 2.730 6.063 U/ml 0.721 compared other correlation between (r = 0.719, p 0.029) a statistically significant result. Therefore, extracts this fruit have promising potential as cheap sources future natural agents in food industry. Researchers will further these results in-vitro in-vivo biological studies.</p>
