Cassia obtusifolia and its seeds, common contaminants of agricultural commodities, are toxic to cattle and poultry. Toxicity has been attributed to anthraquinones which are major constituents of C. obtusifolia, but studies of the subchronic and chronic toxicity of naturally occurring anthraquinones are limited. To investigate the subchronic (greater than 30 days) toxicity of C. obtusifolia seed, ten rats/sex were fed diets containing 0, 0.15, 0.50, 1.5 or 5.0% C. obtusifolia seed for 13 weeks. Intermittent mild diarrhea was found in high-dose animals and body weights of high-dose males were decreased to week 10. Myeloid hyperplasia with peripheral leukocytosis, thrombocytosis and mild anemia were found in males and females fed diets containing greater than or equal to 0.50% C. obtusifolia seed. Leukocytosis resulted from neutrophilia, whereas peripheral lymphocyte counts were unaffected. Lymphoid hyperplasia and/or histiocytosis were found in the mesenteric lymph nodes in groups fed C. obtusifolia seed. Thus, a dietary 'no observable effect level' for subchronic ingestion of C. obtusifolia seed in rats was less than 0.15%. 相似文献

Naturally occurring quinones and quinone-containing extracts of seeds of the toxic plant Cassia obtusifolia (sicklepod) affected muscle mitochondrial function. Aqueous suspensions and organic extracts of C. obtusifolia seeds slightly elevated plasma creatine kinase levels of Sprague-Dawley rats. These extracts were analyzed by fused silica capillary gas chromatography and found to contain nine anthraquinones and three anthrones. Urinary metabolites primarily consisted of beta-glucuronide conjugates of the anthraquinones. The three anthrones or conjugate analogues were not present in the urine in detectable amounts. Emodin, doxorubicin and organic extracts of C. obtusifolia inhibited NADH:cytochrome c oxidoreductase activity of bovine heart mitochondrial particles and NADH:CoQ oxidoreductase activity of porcine heart mitochondrial NADH dehydrogenase, whereas juglone was stimulatory. Relative quinone metabolism correlated with semiquinone formation rate and with redox potential. A protective effect of coenzyme Q against enzyme inhibition by anthraquinones was also observed. 相似文献

目的:建立大鼠血浆中决明子蒽醌类成分的RP-HPLC定量分析方法,并用于大鼠体内蒽醌类药动学研究。方法:采用Zorbax Extend-C18(250 mm×4.6 mm,5μm)(Palo Alto,CA,USA)色谱柱,以乙腈-0.3%醋酸水为流动相进行梯度,流速1.0mL.min-1,检测波长258 nm,柱温28℃。采用RP-HPLC测定决明子中芦荟大黄素(aloe-emodin)、美决明子素(obtusifo-line)和大黄酚(chrysophanol)3个蒽醌类指标成分在大鼠血浆的浓度,并根据测定结果求算药动学参数。结果:建立了决明子中芦荟大黄素、美决明子素和大黄酚在大鼠血浆中的含量测定方法。实验结果表明蒽醌类成分在大鼠体内吸收迅速,消除也较快。结论:本方法简便、准确、专属性强,可以应用于大鼠灌胃给药决明子蒽醌类提取物后的药动学研究 相似文献

目的:探讨固态发酵对决明子中5种蒽醌类成分含量的影响。方法:采用高效液相色谱法测定决明子发酵前后芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚的含量并进行对比研究。色谱柱为C18-ODS反相柱(250mm×4.6mm,5μm),流动相为甲醇-0.1%磷酸水溶液(梯度洗脱),流速为1mL.min-1,检测波长为280nm。结果:决明子经过发酵后,游离型蒽醌含量呈上升趋势。以未发酵成分含量为100%计算,5种成分变化分别为104.6%、102.2%、93.4%、215.6%、134.8%,其中芦荟大黄素、大黄酸和大黄素变化不明显,大黄酚与大黄素甲醚分别增加至2.15倍和1.34倍,可见发酵增加了蒽醌苷元的含量。结论:决明子通过发酵,有利于增加活性成分蒽醌苷元的含量。 相似文献

Three new acetylated anthraquinone glycosides (1-3) were isolated from the seed of Cassia obtusifolia, together with one parent anthraquinone glycoside (1a). Their structures were determined on the basis of spectroscopic methods and physicochemical properties as obtusifoline-2-O-β-d-2, 6-di-O-acetylglucopyranoside (1), obtusifoline-2-O-β-d-glucopyranoside (1a), obtusifoline-2-O-β-d-3, 6-di-O-acetylglucopyranoside (2), and obtusifoline-2-O-β-d-4, 6-di-O-acetylglucopyranoside (3). 相似文献
