关键词： 山茱萸酒   复合澄清剂   透光率  

摘要： 利用皂土和壳聚糖对山茱萸酒澄清效果进行研究。以透光率为评价指标,采用单因素实验和正交试验设计的方法,探讨复合澄清剂配比、水浴温度和添加量对山茱萸酒澄清效果的影响。结果显示,影响山茱萸酒澄清效果的因素主次顺序为水浴温度>皂土-壳聚糖配比>添加量,各因素均为非常显著,最佳工艺条件为水浴温度40℃,皂土-壳聚糖配比1∶1,添加量0.6 g/L;山茱萸酒的稳定性和感官分值均明显增强。

关键词： 唐代   河东   官方信仰   祭祀  

摘要： 唐代河东地区各种宗教信仰活动十分兴盛,其中由政府引导的多神信仰与英雄崇拜成为河东官方信仰的主流。这种世俗权力与思想信仰趋向合流的现象,与统治者力求统治合法化、税收扩大化、思想统一化密不可分,由此衍生的系列祭祀文化与崇拜活动极大提升了河东地区在全国的规格与影响力。

摘要： Cornus kousa (kousa dogwood), used as a landscape tree and a source of food and medicine, is difficult to propagate from seeds owing to dormancy. The present study was conducted to develop an effective method of seed propagation and identify the seed dormancy type. Kousa dogwood seeds were classified as presenting physical dormancy (PY) and physiological dormancy (PD) from an immature embryo. Seeds were contained within an impermeable endocarp that conferred PY and had an undifferentiated embryo that grew and differentiated after scarification and cold moist stratification, leading to improved germination. To break PY + PD, four replicates of 50 seeds (3200 in total) for each treatment were prepared by scarification and cold moist stratification. These methods combined improved moisture absorption and germination more than either treatment alone. In particular, the addition of cold moist stratification treatment to scarified seeds could effectively induce embryo development. By contrast, untreated seeds showed low germination rate of less than 1% at 30 A degrees C with continuous light. Sulfuric acid (H2SO4) at different concentrations and durations was used to uniformly wound the endocarp of seeds. Treatment with 80% H2SO4 for 10 min resulted in the highest germination rate (68.6%) and moisture content (65.7%), which were higher than those following polishing with a brushing machine for 5-40 min. Longer treatment with high concentrations of H2SO4 (80 and 100%) caused the acid to infiltrate the seed and inhibit germination by damaging internal tissues, while low concentrations (40 and 60%) did not affect germination rates even after treatment for more than 10 min. To obtain maximum germination, concentration and treatment duration of sulfuric acid should be carefully controlled.

摘要： In this research, we investigated the profile and bioactivities of quinazoline alkaloids, a class of natural products boasting multiple bioactivities, from the unripe fruit of Evodia rutaecarpa (Juss.) Benth. Three new quinazoline alkaloids, evodiamide A (1), evodiamide B (2), and evodiamide C (3), as well as eight known quinazolines, were isolated from the MeOH extract of E. rutaecarpa. The new compounds are rare quinazolinedione derivatives with linked heterocyclic nuclei. Among these quinazolines, rhetsinine (8) showed potential as a pesticide and exhibited excellent inhibition against Xanthomonas oryzae pv. oryzae, Xanthomonas oryzae pv. oryzicola, and Xanthomonas campestris pv. campestris, with respective EC50 values of 3.13, 14.32, and 32.72 nmol.

摘要： Two polyprenylated acylcyclopentanone racemates, evodialones A (1) and B (2), featuring a 3-ethyl-1,1-diisopentyl-4-methylcyclopentane skeleton, were isolated from an extract of the aerial parts of Evodia lepta. Evodialone A (1) was resolved by chiral-phase HPLC to afford a pair of enantiomers, (+)- and (-)-evodialones A (1b/1a), while evodialone B (2) could not be resolved. Their structures were elucidated by spectroscopic analysis and a combination of computational techniques including gauge-independent atomic orbital calculation of 1D NMR data and experimental and TDDFT-calculated ECD spectra. A putative biosynthetic pathway of 1 and 2 starting from the monocyclic polyprenylated acylphloroglucinols is proposed. All the isolates were screened for the antimicrobial activity in vitro, and 1a and 1b showed moderate inhibitory activities against several pathogenic fungi with MICs values of 17.1-68.3 mu M.

关键词： 茱萸穴位贴   高血压   护理  

摘要： 高血压是最常见的慢性病之一,也是心血管病最主要的危险因素,可导致脑卒中,心力衰竭及慢性肾脏病等主要并发症,严重影响患者的生存质量,给家庭和国家造成沉重负担。患者往往服用2种或2种以上降压药物控制血压[1],由于长期服药,极易导致肝肾功能的损伤以及水电解质紊乱等,同时也会增加患者经济以及心理负担[2],影响了患者治疗的依从性。吴茱萸穴位贴敷通过药物以及穴位的双重刺激达到治疗效果,且该疗法用药量小,成本低,具有节约药物的优点,同时安全性高,依从性好,在临床中对于轻中度高血压效果良好,与常用的降压药治疗效果相当。
