Oroxylum indicum Seed Source & Identity
The botanical entity is Oroxylum indicum (L.) Kurz, the Indian trumpet tree of the Bignoniaceae, a tall tree with giant compound leaves, night-opening bell flowers and flat pods about a meter long that hold thin, winged seeds. The part used is the seed. Bark, pod wall and leaf are not part of this Oroxylum indicum extract.
Different parts of the tree carry different flavone profiles, so the part matters on a specification. The seed holds flavones such as baicalein, chrysin and oroxylin A together with their glucuronides, named here only as families, and the bark contains related compounds in other proportions. The Chinese trade name mu hu die refers to the seed.
