摘要(Abstract):

目的:丹参栽培品、野生品及其不同产地丹参药材性状和显微组织差异比较。方法:药材性状比对,根横切面、粉末显微特征测量和比对。结果:丹参野生品与栽培品在药材性状差异为:丹参野生品根有数条,长圆柱形,表面棕红色或暗棕红色,粗糙,常呈鳞片状剥落。丹参栽培品根多分枝,表面砖红色或红棕色,外皮紧贴不易剥落。显微组织方面差异为:丹参野生品木质部导管有直径较大和较小的相间排列形成的导管束;有的产地样品皮层有石细胞。丹参栽培品无石细胞;导管径向或切向排列,未见导管束。道地药材川丹参与其他产地不同,其根较粗壮肥实,直径可达1.2 cm;质坚实,断面黄褐色,略呈角质样;根横切面木质部导管稀疏,径向排列,维管束19~24束,木纤维少。结论:丹参野生品与栽培品、道地药材川丹参与其他产地丹参在材性状与显微组织存在差异,可以通过药材外观形态、根横切面维管束的排列方式等特征鉴别。
Objective: To compare the differences in shapes and properties and the microscopic frameworks of the wild and cultivated Radix Salviae Miltiorrhizae from different regions.Method: The differences in the shapes and properties,the characters of transverse sections,the powder and disintegrated tissue of roots were compared using microscopic measurement and statistics analysis.Result: The wild Radix Salviae Miltiorrhizae had several long cylinder roots with rough flaky squama skin and brown red or wine culour,the cultivated had root of many branch with cling skin and brick-red or chestnut culour.The difference of microscopic histological structure was that the xylem vessel of wild Radix Salviae Miltiorrhizae had bunched vessel with the rank form of big diameter alternating with small diameter,and had stone cell on samples from some producing region,the xylem vessel of the cultivated had no bunched vessel and no stone cell with the rank form of tangential radial.Radix Salviae Miltiorrhizae cultivated in Sichuan Province is called original-region medicinal materials and named Chuandanshen.Chuandanshen had the differences with the Salviae Miltiorrhizae Radix cultivated in other region.The root of Chuandanshen had 1.2 cm diameter,and was bulky and fat with solid fabric and the fracture with brownish yellow color and cutin-alikeness,its xylem vessel of transverse section of root was thin with the rank form of tangential radial,and 19-24 vascular bundle and a few wood fiber.Conclusion: Salviae Miltiorrhizae Radix of the wild and the cultivated,of the original-region(Chuandanshen) and the other-region,have the differences in the shapes and properties,and the microscopic frameworks.The character can be identified by the differences in the shapes of medicinal materials,and the rank form of vascular bundle of transverse section of root.
