[ ] habitat distribution
Ecological environment : in 500m elevation above the region.
Resource distribution: distribution in Sichuan, Guizhou, Yunnan and other places.
Cultivated [ ]
Biological characteristics of hi cool, moist climate. Sichuan province cultivated in altitude of 1200 ~ 2400m in high and cold mountain area. In 1500 ~ 1800m mountain cultivation for best, root quality, yield are high, should be exposed to the sun, deep soil, rich in humus soil cultivation. Avoid continuous cropping.
Cultivation techniques for seed reproduction : should the recovery 3-4 year plant the seed for. Spring sowing autumn September 3-4 month. Advocate produce an area to take mountain spring, low mountain in autumn. Before sowing, use the ash by adding a small amount of human dung water moisture and seed mix. Dibble, according to the 33-45cm spacing opening point, point to shallow, after fertilization and ash mixed with seeds of each hole, about 10 seeds; a row of 33 ~ 40cm. Each 1hm2 with 7.5-11.25kg.
Field management after emergence, seedling height to be 5 ~ 6cm and 10cm, the thinning 1, 2 to 4 lines per hole seeding. According to the distance of 10cm seeding drill. First years of weeding 3 ~ 5, 2 ~ 3 times every year. Each combination of fertilizer 2 ~ 3, first, 2 apply manure water, or rotten cake; third apply manure water, plant ash, can also be NPK compound fertilizer, urea, and tree root antifreeze. Pest control white rust, early onset can be sprayed with 1 : 1: 120 Bordeaux mixture control. Root knot nematodes, prevention should avoid continuous cropping, selection of disease. Experimental damage 1000 times, use dipterex liquid poison.
[ character ]
Character identification cylindrical, slightly curved, slightly branching, length 25-60cm, diameter 0.5-3cm. Surface yellowish brown or grayish brown, slightly twisted longitudinal wrinkles and lateral mark, and has obvious horizontal long protrusions lenticels; newspaper upper residual woody rhizomes. Quality of tough, not easily broken, section shallow yellow or brownish yellow, vascular punctate, intermittently arranged into a number of concentric with the wheel ring. Gas micro, sweet.
A stout, branched, high flexibility, section shallow yellow is preferred.
Microscopic identification of root transection: cork cork cells for series. Cortical stenosis. In the column, abnormal vascular bundle arranged in intermittent 4-11 wheel, outer vascular smaller, inward gradually. Xylem conduits and fiber. The secondary structure is divided into 2-9 shares. Parenchyma cells contain calcium oxalate crystal sand.
Physicochemical identification this section with UV light was observed under fluorescence, greenish yellow, dropping 1% ammonium hydroxide after significant green fluorescent yellow.
Quality mark" people's Republic of China Pharmacopoeia" 1995 edition rules: the water extract of not less than 65%.
Product specifications: a root on central diameter of more than 1.8cm; two: upper middle diameter of more than 1cm; three: the middle diameter 1-0.4cm, length there is no limit.
[ ] root chemical composition containing beta ecdysterone ( beta Ecdysterone ) [1 ] and trace elements in titanium ( Ti ) (12.5 g / g ) [2 ].
Pharmacological action [ ]
1 protein assimilation the goods contained insect metamorphosis of steroid hormone synthesis with strong egg meat stimulative effect to mice, Ig or IPL hydroxyl of ecdysterone after 2 hours, the mouse liver nuclei, mitochondria and microsome in amino acid precursors incorporation increased, 4 hour action is stronger, the action intensity and 4 - chloro testosterone effect similar to. At the same time in the kidney were also observed in protein synthesis enhances phenomenon, but in 4 hours after the return to their original level. Cyasterone also has a similar effect, daily to mouse 5mcg only, i.e., obvious effect and no toxic reaction.
2 Effect of the goods 3 extracts, namely benzene extract ( A ), ethyl acetate extract ( B ) and alcohol extract ( C ) has on the resistance of mice to fertility and anti implantation effect. ( A ) 250mg / kg dose in the female rat has obvious effect, the effective rate was 100%, ( B ) 250mg / kg rate was 63.7%, and 500mg / kg dose has more than 90% efficiency, ( C ) 500mg / kg antifertility effect of 40-54%. Anti-implantation experiments show that, A500mg / kg rate was 100%, B500mg / kg rate was 66.7%, C500mg / kg rate was 40%, among which A is one of the most significant.
3 other action: This product contains cyasterone have estrogenic activity, immature rat pol0 or 500mg / ( kg d ), a total of 3 days, increase in uterine weight, but had little effect on the ovarian weight. Fluid extract on the uterus of pregnant cats relaxation effect. But to have been pregnant uterus has strong contraction effect.
[ ] the physicochemical identification identification: 1 the goods section, the observed under an ultraviolet lamp, was yellowish green fluorescence; add 1% ammonium hydroxide, significant green fluorescent yellow. In 2 of Achyranthes bidentata saponins under of foam test and hemolysis test were negative.
