The outer surface is dark brown, tender skin smooth, glossy, old skin is rough, turtle crack; horizontal lenticels elliptic, pale brown, cork is thin and tough, but lateral dissection, the off show pale yellow to pale yellow green, microstrip gloss. Inner surface is pale yellow to pale yellowish brown. Brittle, easily broken, irregular cross section. Micro gas smell, taste bitter.
Microscopic identification of phloem transverse: wooden layer thickness, cork cell fusiform, long fusiform, mosaic shape, cell wall bolt and micro wood. Cortical slightly wider, accounted for the transverse section of the 1 / 3 ~ 1 / 4, the stone cell populations scattered, stone cell irregular or branching, length of up to 225 M. Phloem is broad, stone cell clusters or strips are arranged, a round or oval, wall thickness, a clear layer, hole groove and the wall hole, cell small; phloem ray width of 1 ~ 2 columns of cells, some thin-walled cells visible oil drops.
Powder characteristics: sallow skin powder. Stone cells scattered in the individually or in groups, of different sizes, a round, oblong, fusiform, branched, diameter of 60 ~ 255 m, have apparent layer, hole ditch and wall, cell is small, a few stone cells only wall hole. Cork cell yellow or yellow brown, elongated spindle-shaped or fusiform, cells containing the oil droplet. Phloem ray cells were round, often together in 2 rows; thin-walled cells oblong, containing oil droplets.
Physicochemical identification ( 1) coarse powder 5g, the conical flask, 80ml 30min water, decocting, filtering. The filtrate is concentrated to about 10ml, cooling, forced vibration with ether 10ml, 5min, 3ml draw ether solution, adding 10% sodium hydroxide solution 0.5ml, shaking, aquifer was brown, after heating, the color deeper, brown red.
( 2) take the rough 10g, plus ethanol amount, soaking for several hours, filtering, recovery of alcohol flavor, residue and water dissolved with hydrochloric acid, 10% to pH1-2, using ethyl acetate extraction for 3 times, combining the extract liquid, washing with water 5 ~ 10ml, dehydrated by anhydrous sodium sulfate, concentration to dry, ethanol amount dissolved, for the test: take 1ml filtrate, and ferric chloride ethanol solution of 1-2 drop, significant green. According to the preparation of sample and on diluted to certain concentration, with ethanol as blank, as spectrophotometric method." People's Republic of China Pharmacopoeia 1995 version of" appendix ) determination in soil at a wavelength of 282 1nm, with maximum absorption peak.
Pharmacological action [ ]
1 expectorant effects in mice or rabbits orally or intraperitoneally full leather decoction has a significant expectorant effect ( phenol red ), with the same dose equivalent intensity of Platycodon grandiflorum, vagotomy, effect is not affected, directly from the trachea to small drugs can occur, thus may directly stimulate the respiratory tract and effect of. For the ciliated tracheal epithelium movement anti inhibition. Phlegm active ingredient is the acid phenol and flavonoid.
Guinea pig 2 antiasthmatic effects of oral skin decoction has obvious effects of relieving asthma ( Philippine often antihistamine spray asthma method). On effective ingredients of terpenes. Mice gavage is close to the toxic dose of all PI decoction has no effect on relieving cough ( ammonia spray method ). The bark of the ethanol extracts of neutral section on cough effect.
3 on rats with experimental chronic tracheitis role gavage extract 20g / kg, a total of 20 days, no effect on relieving cough, but can reduce III following bronchial epithelial cell hypertrophy and hyperplasia, make various bronchial goblet cell number decreased, tracheal gland hypertrophy and hyperplasia loss and acinar, catheter mucus of quantity reduction, but on chronic inflammatory cell infiltration and lymphoid tissue hyperplasia showed no effect.
4 of the other 4.1. Bacteriostasis full leather and endothelial Decoction against pneumococci and Haemophilus influenza have moderate inhibitory effect, the branch water decoctions have only mild inhibition. Wooden heart decoction has no effect. Full leather Decoction on the reticuloendothelial system phagocytic function and capillary permeability were studied.
4.2. The toxicity in mice orally or intraperitoneally full skin of water decoction of LD50 were greater than 100g / kg and 10.18g / kg. Guinea pig gastric perfusion of 20g / kg / day for adult head when in 20-40 times ) for 20 consecutive days, in addition to sue weight growth was inhibited, electrocardiogram. Liver function. Urinary protein and the visceral pathological examination showed no change. Full leather Decoction on gastric irritation, ethanol and ethyl acetate extract without stimulation.
4.3. The antipyretic effect of other plants in Europe Syringa reticulata ( Syringa vulgaris ) water or acetone extract to the rabbit fever, oral or intraperitoneal injection of cat has a fever.

[ ] the clinical application of treatment of chronic tracheitis: experimental results show, Syringa amurensis various parts to endothelial function is strongest, the skin of the worst, duramen. The clinical use of its tender skin, dosage forms, powder, granule, pill syrup, and Syringa amurensis skin extract etc.. In addition to agents unilateral, and compound preparation, but the two similar results. On simple chronic bronchitis curative effect is higher than that of breathing; expectorant and antitussive efficacy than the antiasthmatic effect. Syringa amurensis antitussive effect is obvious, but not as much as codeine, expectorant effects and dose of the orange fairy comparison, a similar effect. Preparation and usage. One, granule: Syringa amurensis bark decoction combined with washing 2 times, 2 times the filtrate is concentrated into paste and powder mixing, granulation, drying of about 60 DEG c.. 3G each time, 3 times a day. The daily amount of Syringa amurensis bark 1 two. Two, syrup: Syringa tender skin 3 two, green radish 3 two, adding 300ml, fried into 60ml, the amount of sugar added to. 30ml each time, 2 times a day, 10 days for a course of treatment. Three: each pill, pill 3 money (including Syringa tender skin powder 5g, bee treasure 5g ), 1 pills each time, 3 times a day, 10 days a course of treatment. Four, powder: Syringa amurensis skin water decocting 3 times, each time for 1 hours, concentration and spray drying into powder, daily 5 money ( 10 systems ), divided into 3 suits, even served 20 days. Five, Syringa amurensis bark extract from bark of Syringa amurensis: ( in 5 money ( 10 two ) in preparation of total extract of 1.8g, 0.6g each time, 3 times a day, after meals, 10 days for a course of treatment. Efficacy: granules for treatment of 25 cases of the control group, 2 cases, 3 cases, 14 cases improved, invalid 6 examples: syrup group cure in 256 cases, 33 cases were cured, 79 cases, 114 cases improved and 30 cases ineffective; pill treatment group 275 cases, 22 cases were cured, 61 cases improved, 122 cases, 70 cases are invalid; extract group observes 20 examples, after 2 courses, 7 cases were cured, 4 cases, 7 cases improved, 2 cases are invalid. Clothing extract general in the 2-3 days after the start, 6 days has obvious effect, effect 10 days up to a certain height; 10 days later to continue treatment, effective case can continue to improve or tending to cure, but the effectiveness is still valid.
