Corydalis Alkaloids are categorized as natural products of the isoquinoline alkaloid type.[1]
Corydalis alkaloids are primarily located within the roots of Corydalis cava and various other Corydalis species.[1]
The representatives of Corydalis alkaloids include d-tetrahydrocoptisine (also known as d- or (+)-stylopine), d-canadine, and hydrohydrastinine.[2][3]
Corydalis alkaloids exhibit certain narcotic and muscle-paralyzing effects. Historically, the powdered rhizomes of Corydalis alkaloid-containing plants enjoyed popularity as a vermifuge and menstrual stimulant.[1]
