摘要： Actinidine, a methylcyclopentane monoterpenoid pyridine alkaloid, has been found in many iridoid-rich plants and insect species. In a recent research on a well-known actinidine- and iridoid-producing ant species, Tapinoma melanocephalum (Fabricius) (Hymenoptera: Formicidae), no actinidine was detected in its hexane extracts by gas chromatography-mass spectrometry analysis using a common sample injection method, but a significant amount of actinidine was detected when a solid injection technique with a thermal separation probe was used. This result led us to hypothesize that heat can induce the production of actinidine in iridoid-rich organisms. To test our hypothesis, the occurrence of actinidine was investigated in four iridoid-rich organisms under different sample preparation temperatures, including two ant species, T. melanocephalum and Iridomyrmex anceps Roger (Hymenoptera: Formicidae), and two plant species, Actinidia polygama Maxim (Ericales: Actinidiaceae) and Nepeta cataria L. (Lamiales: Lamiaceae). Within a temperature range of 50, 100, 150, 200, and 250 degrees C, no actinidine was detected at 50 degrees C, but it appeared at temperatures above 100 degrees C for all four species. A positive relationship was observed between the heating temperature and actinidine production. The results indicate that actinidine could be generated at high temperatures. We also found that the presence of methylcydopentane monoterpenoid iridoids (iridodials and nepetalactone) was needed for thermally induced actinidine production in all tested samples. These results suggest that the presence of actinidine in iridoid-rich plants and ants might be a consequence of using high temperatures during sample preparation.
