Effects of Natural and Artificial Colorants on Hot Smoked Garfish—Belone belone (Linnaeus, 1761)—Stored at 4 ± 1ºC

In this study, the effects of natural and artificial colorants on the shelf life of hot smoked garfish were investigated in terms of its chemical, microbiological, and sensory quality. Turmeric and Sunset Yellow FCF were used as the natural and artificial colorants, respectively. The amount of total volatile basic nitrogen (TVB-N) and thiobarbituric acid (TBA), counts of total mesophilic aerobic bacteria, total psychrophilic aerobic bacteria, total yeast and molds increased during the storage (p < 0.05). The results showed that turmeric and Sunset Yellow FCF had a significant effect on pH value and salt content of hot smoked garfish samples during storage (p < 0.05). According to the sensory analysis results, the shelf life of hot smoked garfish stored at 4 ± 1ºC was determined as 17 days.     

复方β-环糊精莪术油栓的制备及质量检查

【研究目的】为了防止复方莪术油栓中有效成份的挥发,提高栓剂的溶解性,制备复方β-环糊精莪术油栓;【方法】采用饱和水溶液法制备莪术油β-环糊精包合物,将包合物和甲硝唑等以热熔法制成栓剂并依据兽药典进行质量检查;【结果】试验结果表明在薄层色谱图中,莪术油包合物与莪术油斑点一致,Rf值差异不显著。包合物中含油率为3.6％,油的收率为32.4％,包合物的收率为86.1％。栓剂重量在1.0g～3.0g之间者重量差异限度为±7.5％;栓剂均在30min内全部溶解;【结论】包合过程没有改变莪术油的化学成分,栓剂的质量符合2005版兽药典规定。

超临界CO2萃取与微波法联用提取姜黄有效成分的研究

建立姜黄油及姜黄色素的超临界-微波联合提取工艺,在超临界CO2萃取姜黄油前处理工序的基础上,通过正交试验研究微波法提取姜黄色素过程中各操作参数对提取效果的影响,比较组合工艺与其他工艺在提取条件、产品得率、纯度等方面的差异.优化后得到的最佳条件为:提取温度45 ℃,料液比1:11,乙醇体积分数80%,时间2 min,姜黄色素得率达到3.22%.超临界-微波联合提取工艺完成了姜黄油和姜黄色素的分步提取,而且一定程度上达到了姜黄油和姜黄色素的提取、分离同时实现的效果,更有利于后期精制.     

姜黄及其配伍复方在脑病治疗中的应用规律

目的 研究姜黄及其复方在治疗脑病中的配伍规律,为脑病治疗中应用姜黄提供理论依据。方法 收集古今名家含有姜黄的脑病治疗经验集23首方、综合性医书脑病治疗验方73首,并对96首方中的药物配伍规律进行统计、分析。结果 在96首含有姜黄的脑病治疗方中发现活血化瘀药使用频率高达27.33%,补虚药17.92%,清热药11.38%,解表药10.93%,平肝熄风药8.06%,化痰止咳平喘药5.02%,反映了脑病治疗方中同姜黄配伍的药物使用频率由高到低依次为活血化瘀药、补虚药、清热药、解表药、平肝熄风药、止咳平喘药。将具体配伍药物予以聚类分析可归纳为六类：第一类为姜黄,第二类川芎、当归,第三类红花、黄芪、甘草、丹参、桃仁,第四类僵蚕、白芍、葛根,第五类茯苓、大黄,其余为一类,由此可以直观的得出各类药性的药物同姜黄配伍的高频率代表。结论 依据以上结果得出姜黄能够活血化瘀、理气化痰,配伍补虚药以扶正祛邪,配伍清热药以清利头目,配伍解表药以上行开窍,配伍平肝熄风药以治风先治血等的结论,以便在临床脑病治疗中依据具体证候选择合适的配伍药物。     

Phyto-chemical and pharmacological applications of Berberis aristata

In the recent years, the interest and research in medicinal plants have increased in a great deal. Ayurvedic medicines and formulations developed from ancient Indian herbal systems are renowned for their various important applications. Berberis aristata - an Indian medicinal plant, which belongs to the family Berberidaceae is an ayurvedic herb used since ancient times. It is also known as Indian berberi, Daruharidra, Daruhaldi, Darvi and Chitra.
