RESULTThree compounds were isolated from the ethanol extracts of theleaf of I. indigotica, and identified as indirubin, tryptanthrin and L-pyroglutamic acid.
CONCLUSIONL-pyroglutamic acid was isolated from the genus for the first time, and tryptanthrin was isolated from the leaf of this plant for the first time.
