Chemical compoundTemplat:SHORTDESC:Chemical compound
Galangin adalah suatu flavonol, sejenis flavonoid.
Keberadaan
Galangin ditemukan dalam konsentrasi tinggi pada tumbuhan seperti Alpinia officinarum (lengkuas kecil)[1] dan Helichrysum aureonitens.[2] Ia juga ditemukan dalam rimpang lengkuas[3] dan dalam propolis.[4]
Aktivitas biologis
Galangin telah terbukti memiliki aktivitas antibakteri[5][6][7] dan antivirus secara in vitro.[8] Ia juga menghambat pertumbuhan sel tumor payudara secara in vitro.[9][10]
