It is extracted from fruit clip of the wild plant  "Macleaya cordata 

(Willd.) R. Br", also called as "Pink Plumepoppy" in China. The whole plant 

contains many benzo-c-phenanthridine alkaloids: Sanguinarine 

(pseudochelerythrine), chelerythrine, protopine, α-Allocryptopine, β-

Allocrytopine, bocconoline, sanguirtrine, oxysanguinarine, 

dehydroeicanthifoline, dehydroeicanthifoline, bocconoline, berberine, 

coptisine, corysamine etc.

The fruit clip has much higher content of alkaloids than other parts, 

especially the four alkloids "Sanguinarine (pseudochelerythrine), 

chelerythrine, protopine, α-Allocryptopine, β-Allocrytopine. Our Macleaya 

Cordata Extract (sulfate salt) is in orange yellow powder determinated by 

the sum of contents of Sanguinarine (pseudochelerythrine) and chelerythrine.
