ResumoAlpinia galanga commonly known as Kulingen. Plant is selected for isolation of newer constituents responsible various therapeutic activities like Antidiabetic and anti-inflammatory activities. The purpose of present study to isolate new phenolic glycoside from Alpinia galanga rhizomes. Methanolic extract of Alpinia galanga was column chromatographed and eluted with ethyl acetate-methanol (9:1) to isolate compound AG 13, Galangogalloside. New structure of Galangogalloside was interpreted by various spectral techniques (UV, IR, 1HNMR, 13CNMR, and MS). Chemical investigation of the methanolic extract of the rhizomes of Alpinia galanga furnished new gallic acid glycoside (Galangogalloside). New gallic acid glycoside isolated from medicinal plant or synthetic source for the first time. Key words: AG 13, Alpinia galanga, galangogalloside, gallic acid glycoside, methanolic extract
