摘要(Abstract):

山沉香以其独特的药用价值在我国民族医药应用中发挥着重要作用,现代药理学研究也表明其具有抗心肌缺血、抗菌、抗炎、抗肿瘤、镇痛等功效。山沉香药材取自丁香属植物羽叶丁香的去皮根、茎、粗枝等部位,目前主要根据其横截面的紫色侵填物与香气判断山沉香是否结香,但对其结香机制研究尚未见报道。为了解山沉香结香过程中的微观变化,该文对结香前后的山沉香进行组织化学染色和显微观察,总结山沉香药材的显微结构特征、比较结香前后山沉香的组织化学差异。结果显示,结香前后的山沉香各部位侵填体分布具有显著差异;未结香材料具有较多淀粉粒和活细胞,而结香材料的分布规律相反;山沉香射线细胞的多糖含量和木质化程度随结香程度的加深而增加。该研究表明,符合临床用药要求的山沉香在心材部位含大量紫红色侵填体,黄棕色侵填体在心材与边材都有分布但边材相对较少,射线部位木质化程度很高,具活力细胞少,含大量多糖,几乎无淀粉存在。该研究旨在揭示山沉香结香过程中组织化学特征的改变,为深入探索山沉香的结香机制奠定基础。
Mountain-agarwood plays an important role in ethnic medicine in China for its pharmaceutical value. Modern pharmacological researches demonstrated that mountain-agarwood was effective for its anti-myocardial ischemia, antibacterial, anti-inflammatory, antitumor and analgesic effects. Mountain-agarwood derives from the peeled roots, stems or twigs of Syringa pinnatifolia which belongs to Syringa genus. It often depends on the purple substance and fragrance to estimate the formation of mountain-agarwood. However, the mechanism of mountain-agarwood formation has not been reported. To observe the microcosmic change in the process during the formation of mountain-agarwood, this study described the microscopic and histochemical characteristics of mountain-agarwood formation through histochemical staining. Our results showed that a significant difference of the distribution of tyloses existed during mountain-agarwood formation. It was observed that inchoate mountain-agarwood had more starch granules and viable cells than mountain-agarwood formed with high level or low level. The amount of polysaccharide and degree of lignification were increased during the mountain-agarwood formation. The results indicated that the mountain-agarwood, which meets the quality requirements for pharmaceutical use, contained the following characteristics: a large amount of purple tyloses in heartwood; yellow-brown tyloses distributing in heartwood and sapwood which were less in the latter; lignification with high level; a few viable cells; lots of polysaccharide and few starch granules in xylem rays cell. This study is aimed to reveal the change of histochemical characteristics during mountain-agarwood formation, and lay the foundation for exploring the mechanism of mountain-agarwood formation.
