(1) the cross section of this product: the cork layer is a sequence of brown cells. The cortex is narrower. The phloem ray is wide and curved and often cracks; Fibrous polymorphic bundles, not lignylation or microlignylation, surrounding thin-walled cells often containing calcium oxalate crystals; The screening group is often deformed by compression. There is an obvious layer of cambium. The xylem rays are 3 ~ 5 column cells; The catheter is more, the diameter is about 160 mu m; The wood fibers are bunched and the surrounding thin-walled cells also contain calcium oxalate. The root has no pulp; The root has a pulp. Powder light brown and yellow. The fibers are bundles of fibers, 8 ~ 14 mu m in diameter, and the wall is thick and micro wood, and the surrounding thin-walled cells contain calcium oxalate, forming crystalline fibers. Calcium oxalate crystals are more common. The bordered perforated catheter is large and rare reticulated duct. Cork cells red brown, polygonal, microlignylation.

(2) apply the powder 1 g, plus ether 40 ml, heating reflux for 1 hour, filtration, liquid to add 30 ml of methanol, heating reflux for 1 hour, filtration, the filtrate zhenggan residue 40 ml water to dissolve, with n-butyl alcohol extract 3 times, every time 20 ml, merger, n-butyl alcohol liquid water washing three times, zhenggan residue add methanol 5 ml to dissolve, as the test solution. Another herbal medicine, 1g, was used to control the solution of herbal medicine. The ammonium glycyrrhizin was taken as the control product, and the methanol was prepared with a solution of 2mg per 1ml. According to the thin layer chromatography (appendix Ⅵ B) test, from the above three kinds of solution 1 ~ 2 mu l, each point in the same with 1% sodium hydroxide solution preparation of silica G thin layer plate, with ethyl acetate - formic acid, glacial acetic acid and water (15:1:1:2) as an agent, and taken out, dry spray with 10% ethanol solution of sulfuric acid in the 105 ℃ heating to the spot color is clear, can be examined under a uv lamp (365 nm). In the chromatogram, the fluorescence spots of the same color were displayed in the corresponding position of the control materials. In the corresponding position of the corresponding chromatogram, the same orange fluorescence spot.

Efficacy:

Licorice is a plant with great medicinal value, which is used by Chinese and western medicine. Western medicine has been using liquorice as an anti-phlegm, antitussive and sweet additives from gusila.

Its effect is reflected in whitening, sunblock two respects

Licorice extract whitening effect is mainly by inhibiting tyrosinase and dopa pigment interconvert enzyme (TRP - 2) activity, 2 hydroxy indole block 5, 6 - (DHl) polymerization, in order to prevent the formation of melanin, so as to achieve the effect of whitening skin.

In licorice extract, the components of sunscreen are generally flavonoids. Due to the conjugation of the molecular structure of licorice flavonoids, both uv and visible light show strong absorption. The molecules that absorb the high energy ultraviolet ray migrate from the ground state to the activation state, and then from the activation state to the ground state, releasing harmless and low-energy rays. Compared with synthetic sunscreen, licorice extract is used as a sunscreen and does not need to add antioxidants to the formula. It does not stimulate the skin, and it can absorb better.
