ABSTRACT
OBJECTIVE: To compare and identify Celastrus aculeatus and Kadsura heteroclita with pharmacognosy methods for analyzing the quality of the crude drug. METHODS: Pharmacognosy study on Celastrus aculeatus and Kadsura heteroclite was carried out through plant identification, crude drug identification and microscopic characteristics identification. The characteristics of Celastrus aculeatus and Kadsura heteroclite were compared. RESULTS: There were significant differences between Celastrus aculeatus and Kadsura heteroclite in appearance of cork, attachments on internal surface of cork,shape of leave edge, number of lateral vein, type of stoma and vessel, and the crystals, the stone cells and the fibers in the same part of both drugs. CONCLUSION: The pharmacognosy characteristics of both crude drugs can be used for identification and quality control on Celastrus aculeatus and Kadsura heteroclite.

A new sesquiterpene polyol ester with a beta-dihydroagarofuran skeleton, NW37 (1), and three known compounds NW13 (2), NW16 (3) and NW35 (4) were isolated by bioassay-guided fractionation from the highly polar MeOH extracts of the root bark of Celastrus angulatus. Their chemical structures were elucidated mainly by analyses of MS and NMR spectral data. The insecticidal activity of compound 1 against 4th instar Mythimna separata larvae with a KD(50) value of 252.3 microg g(-1) was demonstrated.
