Corydalis flabellata

Cbelidimerine, an optically inactive alkaloid of the same constitution 31, was isolated from Ch. majus. X-ray analysis indicated the existence of the chiral P2i2i2i space group. Therefore, the authors deduce that it might have been a /MMoisomer of 31 [111]. However, no other X-ray data were reported. Recently, optically inactive cbelidimerine has been found in a Kashmir specimen of Corydalis flabellata Edgew. [112] and Turkish C.
