Beneng taro (Xanthasoma undipes K.koch) is a local wild taro which grows spreading the land area of Gunung Karang in Pandeglang District, Banten Province. Recently, the demand of Beneng taro tubers is increasing due to improvements in its utilization as a food crops. Therefore, Beneng taro is now being cultivated widely by the farmers. However, the use of Beneng taro is still focus on its tubers, while its leaves has not been utilized and only become an agricultural waste. The aim of research was to find out the chemical content of cultivated Beneng taro leaves as a raw material for biopesticide. The research was conducted from July to September 2018. The leaves sample of cultivated Beneng taro were taken from farmer’s field in Juhut Village, Karangtanjung Sub-district. Phytochemical analysis was accomplished in the laboratory. Further, chemical content in the form of alkaloids, flavonoids, saponins, tannins, and oxalic acid were observed. The research result showed that there were negative content for alkaloids, flavonoids, saponins in Beneng taro leaves. The cultivated Beneng taro leaves positively containing tannins, and oxalic acid as much as 3448.20 and 8361.52 mg/kg, respectively. The chemical content of tannins in Beneng taro leaves indicated the potential use of Beneng taro as a raw material for biopesticide.
