Plant Morphology,Microscopic Identification and Component Analysis of Goodyera brachystegia
摘要
Abstract
The morphology and tissue structure of Goodyera brachystegia were studied by pharmacognosy identification method,and the contents of its main components,including kinsenoside,total flavonoids and polysaccharides,were determined by HPLC-ELSD method and UV spectrophotometry.The leaves of G.brachystegia are elliptical or ovate,with green upper surface without white spots and light green underside.The flowers are small,with white petals,oblique rhombus-shaped oblanceolate.The lip is broadly ovate,with light yellow base,and concave into a hemispherical hood.Microscopic identification shows that the ventilation tissue of the root cross-section is well developed,and the vascular bundles are arranged in a radial pattern of multiple archetypes.The vascular bundles of the stem are scattered into a finite external tough type.The lower epidermis of the main vein of the leaves is semicircular and raised,and the stomata of the lower epidermal are mainly indefinite.The average contents of kinsenoside,total flavonoids and polysaccharides in two batches of G.brachystegia were 14.90%,1.52%and 2.05%,Among them,kinsenoside is a distinctive chemical marker that differentiates G.brachystegia from other Goodyera species.The above characteristics can provide a reference for the identification,resource development and utilization of G.brachystegia.关键词
