• Grewia nervosa (Lour.) Panigrahi was distributed in Bangladesh, India, Sri Lanka, Cambodia, Laos, Thiland, Vietnam, Indonesia, Malaysia and Myanmar and it is locally called in Myanmar as Mya-yar. The roots of Mya-yar were collected from Pyin Oo Lwin Township, Mandalay Region, Myanmar. Antidiabetic effect of methanol extract of root of G. nervosa was done at Department of Biotechnology, Mandalay Technological University, Pathein Gyi Township, Mandalay Region, Myanmar. In addition, dihydrochalcone compound was isolated from ethyl acetate extract of the selected sample by thin layer and column chromatography methods. The structure of this compound was elucidated by analysis of NMR spectroscopic and mass spectrometric data.
