Chemical composition of [ ]
1 entire grass-containing pseudo-purslane saponin ( hersaponin ), white sow vegetables glycosides ( bacoside ) A and B. White mother pig dish of Eleutheroside A and B have the same structure, but A is left-handed, glycosides B d-isomer, acid solution obtained after D glucopyranosyl ( D-glucopyranose ), L - pyran glucose ( L-arabinopyranose ) and Arabia white pig mother dish glucoside ( bacogenin ) A1, A2, A3, A4. White mother pig dish glycoside A1 and A2 structure is respectively 20, 24 epoxy - 3, 30 - two hydroxy - 22, 24 - two methyl - 26, 27 - two to - 22 - methyl Adama Xi - 16 - ketone ( 20, 24-epoxy-3, 30-dihydroxy-22, 24-dimethyl-26, 27-dinordammar-22-en-16-one ( 20 ) S ) and 20? Epimer, white pig mother dish glycoside A3 structure of 17, 27 - 20 ( epoxy - 2 - methyl - 1 - allyl ) - D - down - 28, 30 - two to a - 22 - oxygen Wusu - 19 - Xi - 3 - alcohol ( in 17, 27-epoxy-20 - ( 2-methyl-l-propenyl ) - D, 28, 30-trinor-22-oxours-19-en-3-ol ), white pig mother dish glycoside A4 is lactone (ebelin lactone ), Billings; will white pig mother dish of Eleutheroside A degradation can be jujube glucoside ( iujubogenin ) and pseudo jujube glucoside ( pseudojujubogenin ). The grass also contains the D - mannitol ( D-mannitol ), betulinic acid ( betulinic acid ), beans stanols ( stigmastanol ), stigmasterol ( stigmasterol ), beta sitosterol (sitosterol ), twenty-seven ( heptacosane ), twenty-eight alkyl alkyl ( octacosane ), twenty-nine ( nonacosane ), thirty alkyl alkoxy ( TRIACONTANE ), thirty-one ( hentriacontane ), thirty-two alkyl alkyl ( dotriacontane ).
2 stem and leaf flavonoids glycosides composition: apigenin - 7 - glucuronide ( apigenin-7-glucuronoside ), luteolin - 7 - glucuronide ( luteolin 7-glucuronoside ). The root contains Arabia sugar ( arabinose ), RNA ( ribose ) ( xylose ), fructose, xylose, mannose ( fructose ) ( mannose ), glucose ( glucose ), inositol ( inosi-tol ), ( sucrose ) sucrose, maltose ( maltose ).
Pharmacological action [ ]
1 's effects on the central nervous system: white mother pig food ethanol extract in rats with gastric ( 40mg / kg ) for 3 consecutive days, with electric light reaction, initiative conditioned escape response and repeated training avoidance response, observed the goods on learning and memory in rats. The results showed that, the product can obviously promote the normal rats on memory acquisition and memory consolidation. Intraperitoneal injection of mouse pseudo-purslane saponin has sedative effects, but on rat electric shock or mouse PTZ-induced seizures and had no protective effect, but also does not reduce the pentylenetetrazol toxicity, but can be inhibited by reserpine strengthen pentylenetetrazol toxicity, also can reduce the amphetamine toxicity to mouse. Pseudo Portulaca oleracea saponin can also be collaborative cyclobarbital, pentobarbital and ethanol on the hypnotic effect of mice, mice have reduced temperature effect. When the environment temperature from 20 degrees C is raised to 37 DEG C, the synergistic action of hypnotic significantly weakened, a D - lysergic acid two ethylamine treatment, their synergistic hypnotic effect was partially inhibited, this role is also similar with reserpine. The author thinks pseudo-purslane saponin may have a calming effect.
2 other roles: white mother pig food alcohol extract has a strong heart, vasoconstriction, sedation and neuromuscular blocking action. The sugar content of saponins on normal and insufficiency of the frog heart have a strong heart, to rats and guinea pigs have a sedative effect, on the rabbit and guinea pig ileum and rat uterine smooth muscle spasm role.
[ ] this product is toxic to rats by intraperitoneal injection of alcohol extract of the median lethal dose of 331mg / kg, the sugar content of saponins in rats by intraperitoneal injection of the lethal dose of 25.1mg / kg, the doses can cause pulmonary hemorrhage and liver fatty degeneration.

[ usage]: orally taken decoction, 15-30g. External: moderate, decoct soup wash.
