Abstract
This study was conducted to assess the influence of hazard pattern in the surface structure of pollen grains of Campsis grandiflora, and cytotoxicity of different part extracts and nectar on RAW264.7 macrophages. The pollen grains were medium sized ($21.8{\mu}m$) with tricolpate aperture type. In equatorial view, the pollens were prolate (P/E=1.8) and the exine pattern was smooth and reticulate. This result contradict with the rumor of having a hook-shaped protuberance that can damage the cornea because we couldn't observed any protuberance on the surface of the outer wall. Furthermore, we investigated the 70% MeOH extracts (flower, leaf, stem) and nectar of C. grandiflora for their cell viability in temporal basis via MTT analysis on RAW264.7 macrophage cells. There was no significant difference in the cytotoxicity among the MeOH extracts and nectar of C. grandiflora after 24 h. However, nectar showed the dosedependent cytotoxicity on RAW264.7 macrophage cells after 48 h.
