Kenaf (Hibiscus cannabinus L.) is one of the world's most economically important fiber crops. In order to identify different varieties, and investigate its diversity and genetic relationships, twenty-three kenaf accessions and two accessions of its relative, roselle (H. sabdariffa var. altissima), were analyzed by morphological characterization and AFLP(More)
A new orcinol glucoside, orcinol-1-O-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyranoside (3), was isolated from the rhizomes of Curculigo orchioides GAERTN., together with seven known compounds: orcinol glucoside (1), orcinol-1-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside (2), curculigoside (4), curculigoside B (5), curculigoside C (6),(More)
Eighteen novel 3-substituted-indolin-2-ones containing chloropyrroles were synthesized and their biological activities were evaluated. The presence of a chlorine atom on the pyrrole ring was crucial to reduce cardiotoxicity. The presence of a 2-(ethyl-amino)ethylcarbamoyl group as a substituent at the C-4' position of the pyrrole enhanced the antitumor(More)
The structure of the title compound, C(19)H(19)NO(2), contains a seven-membered ring, which is fused to one five- and one six-membered ring, and carries a tolyl substituent. The two benzene rings are oriented relative to each other at a dihedral angle of 86.90 (7)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds.
The asymmetric unit of the title compound, C(13)H(15)NO(2), the main product of a photoreaction, contains two crystallographically independent mol-ecules. In both mol-ecules, the conformation of the seven-membered ring is twist sofa and that of the five-membered rings is envelope. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen(More)
The title compound, C(18)H(16)ClNO(2), is the main product of a photoreaction. The two benzene rings make a dihedral angle of 86.40 (2)° with each other. The 1,3-oxazepine C atom to which the 4-chloro-phenyl group is attached and the C atom of the 4-chloro-phenyl group attached to the 1,3-oxazepine ring are chiral C atoms, but the crystal is a racemate in(More)
