[ source ]
Medicine source: Menispermaceae plant powder impeller ring rattan roots or stems.
Latin animal mineral name: Cyclea hypoglauca ( Schauer ) Diels
Harvest and storage: collected all the year round, go to the roots or branches, wash, cut, dried.
[ ] the original morphology of powder impeller ring winding vine vine. Root stout, cylindrical bending, diameter 1-2cm, outer bark grey brown. Old stems longitudinally twisted coarsening of stripe, branchlets slender, except the leaf axils or branch office with tufted hairs, Yu are glabrous. Leaves alternate; petiole slender, long 1.5-4cm; leaf blade thinly papery, broadly ovate-triangular to ovate, long 2.5-7cm, 1.5-5cm wide, apex acuminate, base nearly truncate to rounded, margin entire, both surfaces glabrous or sparsely white hairy below. Inflorescences axillary; flowers unisexual, dioecious; male inflorescences by cymules arranged into interrupted spikes, rachis of inflorescences unbranched or sometimes close base the Ministry has short branched, slender, glabrous; male sepals 4 or 5, separation, which is of 1mm length; petals 4 or 5, usually connate into a cup, synandria slightly stretched out; female inflorescence arranged in racemes, up to 10cm; female sepals 2, petals 2, tiny, adnate to the sepals basally. Drupe subglobose, ripe yellow. Flowering of 5-7 months, fr. 7-9.
[ ] habitat distribution
Ecological environment : in sparse forests, thickets, mountain forest margins or grass.
Resource distribution: distribution in Hainan, Guangdong, Guangxi, Yunnan, Guizhou, Hunan, Jiangxi, Taiwan, Fujian and other places.
[ character ]
1 character identification cylindrical, slightly curved, diameter 0.5-3cm. The surface is dark brown, rough, with a curved, transverse crack longitudinal groove and a few branches. Hard, section gray, radial texture and small hole. Gas micro, bitter in taste.
2 microscopic root transection: cork layer is composed of nearly 10 columns of cells. Pericycle cells for discontinuous rock band. Ray width. Formation of layer. Xylem developed, catheter suborbicular, multiple single distribution. The parenchyma cells contain starch grains.
[ ] powder chemical composition of impeller ring vine roots contain cycleanine alkali ( cycleanine ), left-handed curarine (curine), with Gu Shu base (isochondredendrine ), CycleA phenolic base ( cyclanoline ), berbamine ( berbamine ), different effects of tetrandrine ( Isotetrandrine ) and magnoflorine ( magnoflorine ); stems containing an alkali, alkali and Gu Shu left curare cycleanine alkali.
[ identify ] physicochemical identification ( 1) take the coarse powder 1g, plus ethanol 10ml, soak overnight, filtration. Filtrate evaporated residue with dilute hydrochloric acid, 4ml dissolution, filtration. With 1ml filtrate, plus modified bismuth potassium iodide solution 2 drops, resulting in a large number of orange precipitate. Another 1ml filtrate, iodized potassium solution 2 drops of mercury, resulting in a large number of white precipitate. ( check the alkaloids ) ( 2) thin layer chromatography takes this coarse powder 10g, ethanol 50ml back to 1H, put cold, filtration. Concentrated filtrate decompression to stem, residue with 20% hydrochloric acid solution 5ml dissolution, filtration. Leachate ammonia water alkaline, with benzene extraction for 3 times with benzene, decompression concentrating the extracted liquid to dry, apply a small amount of residue dissolved in chloroform solution for other of Gu Shu base, l, curine, CycleA alkali for reference. Suction control liquid solution, amount of sample in alkaline silica gel G thin-layer plate, with chloroform and methanol ( 9: 1), from the 13cm exhibition. To blunt iodide potassium reagent spray color, probational liquid chromatography in control samples and the corresponding position, was the same color spots.
