<![CDATA[Butterfly pea (Clitoria ternatea L.) has been widely used as a healthy drink as well as traditional medicine. This study aimed to test the antioxidant activity of C. ternatea aqueous extract based on its ability to inhibit lipid peroxidation (in vitro) using different parts and extraction methods. Extraction was carried out on flowers, leaves, and roots. The leaves and roots were extracted by boiling technique. Flowers were extracted in 3 ways: boiling, maceration, and brewing. Antioxidant activity was determined based on phenolic content, flavonoid content, and antioxidant test using the TBA method. The highest phenolic and flavonoid levels were shown by the aqueous extract of C. ternatea leave of 57.51 mg GAE/g and 1.50 mg EK/g, respectively. The highest levels of flavonoid were from flower parts treated with boiling technique (0.88 mg EK/g), followed by brewed flowers and macerated flowers. The highest antioxidant activity was obtained from flowers that were boiled for 30 minutes with a percentage inhibition of 94%. Based on the method of extraction and part of the plant, all extracts of C. ternatea have similar antioxidant potential.]]>
