[Study on toxicity of vinegar-processed Kansui Radix on basis of symptom-based prescription theory].

OBJECTIVE: To study the differences in the toxicity of vinegar-processed Kansui Radix on normal and cancerous ascites model rats. METHOD: Normal and cancerous ascites model rats were taken as the research objects and orally administered with different doses of vinegar-processed Kansui Radix for 7 d. Pathological sections were prepared to observe the damages in liver, stomach, intestinal tissues in rats and detect the impacts on serum, liver, stomach and intestinal tissues and the oxidative damage index. RESULT: Compared with the blank group, all of normal administration groups and model groups showed significant damages in liver, stomach and intestinal tissues. Compared with the model groups, all of normal administration groups revealed notable alleviation in damages. Compared with the blank group, the model groups showed significant increases in AST, ALT and MDA in serum and liver (P < 0.01) and a significant decrease in GSH in serum and liver, stomach, intestinal tissues (P < 0.01). Compared with the blank group, the results showed significant decreases in ALT, AST in serum and ALT in liver in model low, medium and high dose groups and AST activity in liver tissues in the normal high dose group (P < 0.05, P < 0.01); significant decreases in GSH in serum and stomach tissues in normal low, medium and high dose groups and GSH content in liver and intestinal tissues in normal medium and high dose groups (P < 0.05, P < 0.01); notable rises in MDA in liver tissues in normal low, medium and high dose groups and MDA content in serum and stomach and intestinal tissues in normal medium and high dose groups (P < 0.05, P < 0.01). Compared with model groups, data revealed significant decreases in ALT, AST in serum in model low, medium and high dose groups, AST in liver tissues of model medium and high dose groups and ALT activity in liver in the model high dose group (P < 0.05, P < 0.01); significant increases in GSH content in serum and stomach tissues of model low, medium and high dose groups, GSH in liver tissues in model medium and high dose groups and GSH in intestinal tissues in the high dose groups (P < 0.05, P < 0.01); and notable declines in MDA content in serum in model low, medium and high dose groups, MDA in liver tissues of model medium and high dose groups and MDA in stomach and intestinal tissues the high dose group (P < 0.05, P < 0.01). CONCLUSION: According to the study, vinegar-processed Kansui Radix showed a significant lower toxicity liver, stomach, and intestines of cancerous ascites model rats, which provided a basis for clinical safe application of vinegar-processed Kansui Radix based on symptom-based prescription theory.

[Filtration of active fractions with function of expelling water retention with drastic purgative from Kansui Radix stir-baked with vinegar].

To study the function of expelling water retention with drastic purgative of different polarities of Kansui Radix stir-baked with vinegar on the cancerous ascites model rats, the furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with vinegar for 7 d. The amount of urine and ascites, the level of urinary sodium, potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups, ethyl acetate extract group showed a decreasing trend in ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary sodium, potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of petroleum ether extract and n-butanol extract were weaker than that of ethyl acetate extract. The water exact was the weakest. The results showed that ethyl acetate extract is the active part of Kansui Radix stir-baked with vinegar on the function of expelling water retention with drastic purgative on the cancerous ascites model rats, alleviating the water-electrolyte disorder and body fluid acid-base imbalance, regulating the renin angiotensin aldosterone system.

[Purification of total paeony glycoside by macroporous resin with double indices of albiflorin and paeoniflorin].

OBJECTIVE: To investigate the purification process of total paeony glycoside (TPG) from Radix Paeoniae Rubra by macroporous resin with double indices of albiflorin and paeoniflorin. METHODS: HPLC was used for simultaneous determination of albiflorin and paeoniflorin and the results were used as main indices to investigate the technological parameters for purifying TPG by D101 macroporous resin. Then the result was verified by ampliate test. RESULTS: The applicable technological conditions of purification for TPG by D101 macroporous resin were as follows: the concentrations of albiflorin and paeoniflorin in original solution were 0.12 mg/mL, 2.58 mg/mL with a flow rate of 3.6 BV/h, and the adsorption capacity were 0.71 mg/mL, 15.43 mg/mL, respectively. The eluant was 20% alcohol with 8 times of resin volume, and the elution ratio were 72.18%, 90.84%, respectively. The result of ampliate test accorded with that of small test. CONCLUSION: D101 macroporous adsorption resin can be used to purify TPG from crude extracts of Radix Paeoniae Rubra.
