アスチルビン(Astilbin)は、フラバノノールの一つである。アスチルビンは(2R-trans)型異性体、ネオイソアスチルビンは(2S-cis)型異性体、イソアスチルビンは(2R-cis)型異性体である[2]。
天然の存在
アスチルビンは、セイヨウオトギリ、Dimorphandra mollis[3]、Harungana madagascariensisの葉[4]、Astilbe thunbergiiの根茎、Astilbe odontophyllaの根[5]、ドブクリョウの根茎[6]、Hymenaea martianaの樹皮[7] で見られる。
食品
Engelhardia roxburghianaから作られる黄杞茶から単離される[2]。特定の種類のワインにも含まれる[8]。
利用
ヤガ科のAnticarsia gemmatalisとSpodoptera frugiperdaに対する殺虫剤として作用する[3]。また、in vitroでの抗菌活性[4]及び火傷治癒の活性[5]を示す。中国医学で用いられる[6]。
関連化合物
3'-O-メチルアスチルビンは、接触皮膚炎に対する免疫抑制活性を示す[9]。
