【摘要】 [Objective] To study the pharmacognostical characteristics of Rhaphidophora hongkongensis Schott. [Method] The pharmacognostical characteristics of R. hongkongensis stem, leaf and medicinal powder were studied through morphological, microscopic, physical and chemical identification. [Result] The cross sections of R. hongkongensis stem and leaf were characteristic of monocotyledons. That is, large secretory cavity was below the epidermis of stem, closed collateral vascular bundle scattered in the cortex and pith, calyptrate fiber bundles was on the outer surface of phloem, large xylem vessels were in the center of stem; endoderm was obvious; the main vein of leaf cross-section was mostly scattered in the closed collateral vascular bundle, most of the spongy tissue were scattered in the secretory cavities. Large stellate hairs could be seen in the whole plant powder; common druse was single or clustered in the parenchyma cells; number of calcium oxalate raphides was large; color reaction and TLC reactions were positive for steroids. [Conclusion] The experiment studies the pharmacognostical characteristics of R. hongkongensis, which provides scientific basis for the identification of medicines.
