苦丁茶中熊果酸的分离纯化研究

 目的研究苦丁茶(Ilex kudingcha C.J.Tseng)中熊果酸的分离纯化,建立分离纯化工艺条件,以利于苦丁茶资源的开发利用。方法以熊果酸浸出率为考核指标,采用正交实验法考察诸因素对浸出率的影响。乙醇提取液经沉淀富集和大孔树脂柱色谱纯化得到熊果酸,采用HPLC分析检测。结果优化的提取条件为:在85℃水浴中,以体积分数90％乙醇水溶液为提取溶剂。固液比为1:14,提取2次,每次提取2.5h,熊果酸的浸出率可达到1.44％。D₈树脂分离富集的最优条件:样品溶液熊果酸浓度1～2 mg·mL^-1,样品溶液pH=6.0～7.0,吸附1h,洗脱剂pH=11.0,依次用水、4倍体积30％乙醇、4倍体积90％乙醇以2～3mL·min^-1的流速洗脱,收集90％乙醇洗脱液,熊果酸回收率为97.82％,纯度为95.0％。结论 该工艺产品纯度高,收率高,可实现工业化。     

毛冬青(IP)作为鼻咽癌放射治疗增敏剂的临床观察(Ⅰ)

本研究首次采用毛冬青(IP)对102例鼻咽癌患者进行临床对照试验,其目的是观察IP对鼻咽癌是否有放射增敏作用。结果表明,IP+放射组在治疗后2～3个月内鼻咽肿瘤肉眼和CT的全消率分别为100％和57.1％,均明显高于放射组(71.2％和29.5％);颈淋巴结消失时的平均放射剂量也明显低于放射组,增敏比达1.54;临床Ⅲ、Ⅳ期的全消率也以IP+放射组为高。说明IP能提高放射对鼻咽癌原发肿瘤及颈淋巴结的近期灭癌效应(尤其对中晚期者效果更好)。本文还显示使用IP联合放射是安全的,不但不会增加皮肤和胃肠道的放射反应,而且对口咽粘膜反应还有一定减轻作用。对IP的放射增敏机制也进行了探讨。     

大叶冬青化学成分研究

目的研究大叶冬青中的化学成分。方法应用硅胶及Sephadex LH-20凝胶柱色谱法对其化学成分进行分离,并利用核磁共振（NMR）和质谱（MS）等方法鉴定分离得到的化合物。结果从大叶冬青的干燥叶中分离得到8个化合物,分别鉴定为羽扇豆醇、熊果酸、23-羟基齐墩果酸、熊果醇、27-羟基-α-香树脂醇、坡模酸、3β,23-二羟基乌索-12-烯-28-酸、羽扇-20（29）-烯-3β,24-二醇。结论该植物具有较好的研究价值。     

HPLC法测定救必应药材中冬青素A的含量

目的 建立救必应药材中冬青素A的含量测定方法.方法 采用反相高效液相色谱法.色谱柱:Diamonsil C18柱(250 mm×4.6 mm,5μm);流动相:乙腈(A)与0.4％磷酸(B),梯度洗脱;体积流量:1mL·min-1;检测波长:210 nm;柱温:25℃;进样量:20 μL.结果 冬青素A在12.5～500 μg·mL-1范围内与峰面积呈良好的线性关系(r=0.9998),平均回收率为99.22％,RSD=1.85％(n=6).结论 该方法简便、准确、可靠且分离度好,可用于救必应药材中冬青素A的含量测定.     

Genus Ilex L.: Phytochemistry, Ethnopharmacology, and Pharmacology

The genus Ilex L. has been used as remedies in traditional Chinese medicine in Aquifoliaceae and beverages for thousands of years due to abundant pharmaceutical bioactivities. There are 600 species in genus Ilex L. containing various compounds such as terpenoids, saponins, glycosides, etc. Three species, I. cornuta, I. chinensis, and I. rotunda have been admitted in Chinese Pharmacopoeia 2015 to treat dyspepsia, stomatitis, and hyperactivity cough and protect the liver and kidney. Recent studies showed that several species have been daily drunk to promote human health and prevent cardiovascular diseases in the folk. Here we reviewed the genus Ilex L. in phytochemistry, ethnopharmacology, and pharmacology.     

Appraisal of anti-inflammatory and free radical scavenging activities of ethanol extract of Ilex ficoidea Hemsl and Ilex centrochinensis S.Y. Hu

This study was to appraise the anti-inflammatory and free radical scavenging activities of ethanol extracts of Ilex ficoidea Hemsl (EIFH) and Ilex centrochinensis S.Y. Hu (EICC). Anti-inflammatory activities were evaluated using xylene-induced ear edema and the cotton pellet granuloma tests. Some antioxidants produced during chronic inflammation were quantitated and the DPPH, superoxide anion and hydroxyl free radicals scavenging activities in vitro were also investigated. EICC showed a significant anti-inflammatory effect during the acute inflammation and chronic inflammation without any acute oral toxicity. However, EIFH exhibited a negligible anti-acute inflammatory and a moderate anti-chronic inflammatory activity. EICC significantly inhibited the formation of MDA and markedly raised the activities of SOD, CAT and GSH-Px. EIFH could reduce the level of MDA and elevate the activity of SOD only at the high dose. The free radical scavenging activities of EICC are higher than that of EIFH. These results suggest that EICC possesses significant anti-inflammatory and free radical scavenging activities. The anti-inflammatory mechanism is attributed, in part, to enhance the activities of antioxidant enzymes.
