Product Name: Vitex oil Appearance: clear liquid with light yellow to orange color, Vitex oil has special aroma, spicy flavor. Vitex oil is soluble in Anhydrous ethanol, chloroform or ether any immiscible, almost insoluble in water.
Relative density: 0.890 to 0.910
Refraction rate: 1.485 ~ 1.500
Identification of Vitex oil: (1) the sodium nitrite is about 0.1g, 1~2 drops of water dissolved, add the product of 0.3ml and 0.5ml of dilute sulfuric acid, shaking, oil was green.
(2) take this product 1 drops, add chloroform and 1ml, and chloroform solution dropping 5% bromine, bromine color faded, placed to add 5% bromine chloroform solution to micro yellow, fade, green.
(3) take the product 0.1 ml, plus ethyl acetate 4ml, shake to dissolve, as the test product solution. Another control method with Vitex oil extract, extract solution made from control. Thin-layer chromatography test, draw the two solution 2 L, respectively in the same thin layer plate of silica gel G, petroleum ether (30 ~ 60 DEG C) - ethyl acetate (10:0.3) as the agent, start out, dry, spray with 10% sulfuric acid ethanol solution of vanillin in 5%. Heating to 105 DEG C to spot color clear. In the chromatogram of the sample, the spot of the same color (no less than 4 spots) was found at the corresponding position of the control extract.
