Overview

Valerian Rhizome and Root is the dried rhizome and root of Valeriana jatamansi Jones (Fam. Valerianaceae). The drug is collected in autumn, removed from soil and sand, and dried.

Description

Rhizome cylindrical, slightly flattened, slightly curved, few branches, 1.5-8cm long, 0.5-2cm in diameter; surface dark brown or grayish-brown, with closely spaced nodes and pointed root scars, some slightly swollen at the top, with stem and leaf remnants; texture firm, not easily broken, fracture slightly flat, yellowish-brown or grayish-brown, visible vascular bundle points (vascular bundles) arranged in a ring. Roots slender, slightly curved, 3-15cm long, diameter about 0.2cm, with shallow longitudinal wrinkles, brittle texture. Odour, characteristically aromatic; taste, slightly bitter and pungent.

Identification

（1）Cross-section of the rhizome: 1 column of epidermal cells, square or oblong-shaped, light brown, thickened outer wall, wood embolization, sometimes non-glandular hairs or glandular hairs, some wood plug layer outside no epidermal cells. The cortex is broad, and root or leaf traces are commonly vascular; The endothelial layer is pronounced. The externally tough vascular bundle is multiple, arranged intermittently in a ring. The medulla is broad. Parenchymal cells contain numerous yellowish-brown needle-like or fan-shaped hesperidin crystals. This product powder gray brown. There are many starch grains, single grains round, oblong or ovate, some pointed at one end, diameter 5~39μm, umbilical point crack, tridental or pointed, some visible layer lines; The compound granules are composed of 2~4 grains. The catheters are mainly reticulated catheters and monostriated catheters. Parenchymal cells contain light tan and hesperidin crystals.

（2）To 0.2g of the powder add 5ml of ether, shake for 5 minutes, filter, evaporate the filtrate to dryness, dissolve the residue in 0.5ml of methanol as the test solution. Take valtrate CRS and acevaltrate CRS, dissolve in methanol to produce a mixed solution containing 1mg per ml as the Reference solution. Carry out the method for thin layer chromatography<0502>, using silica gel GF254 as the coating substance and a mixture of petroleum ether (30-60°C) and acetone (5:1) as the mobile phase. Apply separately to the plate 5μl of the test solution and 2μl of the Reference solution. After developing and removal of the plate, dry in air. Examine under ultraviolet light at 254nm. The spot in the chromatogram obtained with the test solution corresponds in position and colour to the spot in the chromatogram obtained with the Reference solution.

Overview

Jatamans Valeriana Rhizome is the dried rhizome and root of Valeriana jatamansi Jones (Fam. Valerianaceae). The drug is collected in autumn, removed from soil, and dried in the sun.

Description

Rhizome cylindrical, slightly flatten and curved, less branched, 1.5-8 cm long, 0.5-2 cm in diameter; externally dark brown or greyish-brown, with dense and raised annular nodes and gibbous dotted root scars, sometimes enlarged slightly at the top ends, with remains of stems and leaves; texture compact, uneasily broken, fracture slightly even, yellowish-brown or greyish-brown, dotted vascular bundles in a discontinuous ring. Root slender, slightly sinuous, 3-15 cm long, about 0.2 cm in diameter, with shallow longitudinal wrinkles; texture fragile. Odour, characteristic; taste slightly bitter and pungent.

Identification

（2）取本品粉末0.2g，加乙醚5ml，振摇，放置5分钟，滤过，滤液挥去乙醚，残渣加甲醇0.5ml使溶解，作为供试品溶液。另取缬草三酯对照品、乙酰缬草三酯对照品，加甲醇制成每1ml各含1mg的混合溶液，作为对照品溶液。照薄层色谱法（通则0502）试验，吸取供试品溶液5μl、对照品溶液2μl，分别点于同一硅胶GF254薄层板上，以石油醚（30～60℃）-丙酮（5：1）为展开剂，展开，取出，晾干，置紫外光灯（254nm）下检视。供试品色谱中，在与对照品色谱相应的位置上，显相同颜色的斑点。
