[Morphological, microscopical and UV spectral identification of herba visci ovalifolii]
Objective:
To identify herba Visci ovalifolii, Chinese medicinal materials used in Li and Miao nationalities.
Methods:
Morphological, microscopical and UV spectral methods.
Result:
Dichotomous branch with a yellow surface, with leaf of 3-5 acrodromous veins originating at the base of the leaf. In transverse section, the thick outer wall of the epidermis of stem projecting like nipple; stone cells contain frequently a prismatic crystal of calcium oxalate, often occur in the cortex and phloem of the stem. Pericycle fibres and xylem fibres all with a well-developed thick wall; vessels with a bordered pits somtimes have a spiral thickened interwall; mesophyll homogeneous contain cluster crystals (not calcium oxalate); stomata present on both surfaces, mostly paracrytic, with small and narrow subsidiary cells. Hairs absent at the surface.
Conclusion:
Above morphological and microscopical characters may be used for the identification of herba Visci ovalifolii. UV spectral method is a simple identificating method for herba Visci ovalifolii.
