The universality and sufficiency of the five-factor model in the Chinese context were investigated. In Study 1, analysis of the Revised NEO Personality Inventory (NEO-PI-R) and the Chinese Personality Assessment Inventory (CPAI) taken by Chinese students showed four joint factors similar to the domains of the NEO-PI-R. Two unique factors were obtained. The Interpersonal Relatedness factor was defined only by CPAI scales. The Openness domain, however, was not represented in the CPAI scales. In Study 2, involving Chinese managers, the robustness of the Interpersonal Relatedness factor was demonstrated. In Study 3, the six-factor model was confirmed with Hawaiian students. Further analyses showed that the six-factor models were superior to the five-factor models and that the Interpersonal Relatedness scales could not be consistently explained by a combination of the Big Five factors. Implications for the universality of the five-factor model and the cross-cultural relevance of the CPAI Interpersonal Relatedness factor are discussed.

Seven new neolignan glycosides ( 1- 7), two arylglycerol glycosides ( 8, 9), and 18 known glycosides have been isolated from an ethanolic extract of the root of Iodes cirrhosa. Their structures including absolute configurations were determined by spectroscopic and chemical methods. Based on analysis of the NMR data of threo and erythro 8-4'-oxyneolignans and arylglycerols in different solvents, the validity of J 7,8 and Deltadelta C8-C7 values to distinguish threo and erythro derivatives was discussed. In the in vitro assays, compound 4 and liriodendrin ( 17) both showed activity against glutamate-induced PC12 cell damage at 10 (-5) M.

Three pyridinium inner salt alkaloids, lonijaposides A-C (1-3), based on an unprecedented skeleton of an N-substituted nicotinic acid nucleus coupled through C-5 with C-7 of a secoiridoid, together with seven known iridoids, have been isolated from the flower buds of Lonicera japonica. Their structures were elucidated by spectroscopic and chemical analyses. Lonijaposide C (3) showed activity against the release of glucuronidase in rat polymorphonuclear leukocytes induced by the platelet-activating factor.
