[Differences in shapes and properties and microscopic frameworks of wild and cultivated Radix Salviae Miltiorrhizae from different regions].
OBJECTIVE
To compare the differences in shapes and properties and the microscopic frameworks of the wild and cultivated Radix Salviae Miltiorrhizae from different regions.


METHODS
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.


RESULTS
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.


CONCLUSIONS
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.
