Robinin and two novel glycosides: isorhamnetin 3-(6-rhamnosylgalactoside)-7-rhamnoside and 3-(2,6-dirhamnosylgalactoside)-7-rhamnoside were isolated from a leaf extract of Rhazya stricta. Naringinase catalysed hydrolysis of both glycosides removed the rhamnose from the 7-hydroxyl. The product isorhamnetin 3-(2,6-dirhamnosylgalactoside) was shown by 1H NMR to be identical with a glycoside previously isolated from Primula veris.
