Özet

The title compounds Tazettine (C18H21NO5) and Corydaldine (3,4-dihydro-6,7-dimethoxy-1(2H)-isoquinolinone, C11H13NO3) have been isolated from the bulbs of Pancratium maritimum L. (Amaryllidaceae) and Corydalis solida subspecies brachyloba, respectively. The X-ray structures were solved for Tazettine (I) and Corydaldine (II) (lambda MoKa, R = 0.0499 and 0.0418. respectively). Crystals of (I) are orthorhombic, a=7.115(1), b=13.377(1), c=16.878(1) Angstrom, Z=4, D-calc=1.370 g . cm(-3) space group P2(1)2(1)2(1). Crystals of (II) are monoclinic, a=10.641(1), b=6.636(1); c=14.938(1) Angstrom, beta=90.31(1)degrees: Z=4, D-calc=1.305 g . cm(-3), space group P2(1)/a.
