藤黄檀结香树脂的性状和显微鉴别研究

Morphological and Microscopic Identification of the Resin of Dalbergia hancei Benth

[目的]对藤黄檀结香树脂进行组织形态学研究,为其鉴定提供依据。[方法]采用性状和显微鉴别方法对藤黄檀结香树脂进行鉴别。[结果]藤黄檀茎表皮灰褐色,结香树脂红褐色、棕褐色或紫褐色;断面可见明显管孔;味辛。显微鉴别结果显示,横切面导管多为单管孔,散生,轴向薄壁组织带状;弦切面木射线非叠生,宽1~5列,高7~56个细胞,径切面木射线组织异型,多为横卧长方形,少数方形和直立形。粉末及解离组织可见木纤维、具缘纹孔导管、木薄壁细胞和木射线细胞。[结论]该研究明确了藤黄檀结香树脂的性状特征和显微特征,所建立的方法操作方便、准确可靠,可为藤黄檀结香树脂的鉴别提供依据。

[Objective]The histomorphological study of Dalbergia hancei resin was carried out to provide basis for its identification.[Method]Morphological and microscopic identification were used to identify the resin of Dalbergia hancei.[Result] The surface of Dalbergia hancei stemsis was gray-brown, and the resin parts were reddish brown, tan or purple-brown, which tastes slightly spicy.The vessels were obvious in the cross section.The results of microscopic identification showed that the ducts in the transverse section were mostly single pore, scattered, and the axial parenchyma was banded.The vessels were obvious in the cross section.Microscopic features: On the transverse section, the vessels often existed alone and scattered, and the axial parenchyma was arranged in bands.On the tangential section, the wood ray was not overlapping structure, the width of the cells varied from 1 to 5 rows, and the height of cells ranged from 7 to 56 cells, and on the radial section, the wood rays cells were heteromorphic, mostly lying rectangular, a few square and upright.There were wood fibers, bordered pit vessels, wood parenchyma cells and ray cells in the powder and dissociated tissues.[Conclusion]This study clarified the macroscopic and microscopic characteristics of the resin of Dalbergia hancei.The method is convenient, accurate and reliable, and can provide a basis for the identification of the resin of Dalbergia hancei.
