As baicalin is a flavone glycoside, it is a flavonoid. It is the glucuronide of baicalein.

Natural occurrences

Baicalin is found in several species in the genus Scutellaria, including Scutellaria baicalensis,[1] and Scutellaria lateriflora. There are 10 mg/g baicalin in Scutellaria galericulata leaves.[2] It is also present in the bark isolate of the Oroxylum indicum tree.

Medical uses

Baicalin is one of the chemical ingredients of at least two herbal supplements: Shuanghuanglian[1] and Sho-Saiko-To, which is a Chinese classic herbal formula, and listed in Japan as Kampo medicine.Script error: No such module "Unsubst".

Baicalin, along with its aglycone baicalein, is a positive allosteric modulator of the benzodiazepine site and/or a non-benzodiazepine site of the GABAA receptor.[3][4][5] In mice, baicalin produces anxiolytic effects without sedative or myorelaxant effects.[6][7] It is thought that baicalin, along with other flavonoids, may underlie the anxiolytic effects of S. baicalensis and S. lateriflora.[8][9]

Baicalin is a known prolyl endopeptidase inhibitor.[10] It induces apoptosis in pancreatic cancer cells.[11]
