1) Berberis laurina Billb. (Thunb.) is relatively rich in berberine but very poor, if not lacking, in hydrastine.  It contains various other alkaloids not identified as yet.  It can be used as a substitute as well as a means of falsification for Hydrastis canadensis.  L.

2) Exts. made from the Brazilian plant Berberis laurina contain 0.84-0.22% hydrastine, comparing favorably with that of ext. of Hydrastis as required by the American pharmacopeia.
