Mangoes are an abundant local fruit. Mango seed is a biowaste material that only becomes an environmental problem. Therefore, a study was conducted to utilize one of the compounds contained in mango seeds particularly the seeds of the Arummanis (Mangifera indica L.) from Indonesia, namely flavonoids. One of the most optimum methods is used for extraction with a variety of solvents, namely ethanol, methanol, and hexane. Determination of total flavonoid content is based on the AlCl3 method with total flavonoids content expressed in QE (Quercetin equivalent) at a maximum wavelength of 425 nm. The results showed that the most optimal total flavonoid content was from ethanol extract with the reflux method of 3.234 mg QE/g extract. © Published under licence by IOP Publishing Ltd.
