Its primary constituents are tannins and saponins. other constituents include volatile oil and gallic acid, with flavonoids also present in the leaves.

Calculate Digit Verification of CAS Registry Number 84696-19:
(7*8)+(6*4)+(5*6)+(4*9)+(3*6)+(2*1)+(1*9)=175
175 % 10 = 5
So 84696-19-5 is a valid CAS Registry Number.
