山楂圆柏锈病的研究

山楂圆柏锈病病原为亚洲胶锈菌，冬孢子在圆柏属，锈孢子和性孢子在山楂属和梨属树木上。从担孢子产生到性孢子12-20d，到锈饱子35-40d，到冬孢子近2a。孢子萌发最适温度为：冬孢子17-20℃，担孢子15-23℃，锈孢子10-25℃，各种孢子均在相对温度50%以上和蔽荫或黑暗条件下萌发，直射光，全光抑制萌发，冬孢子胶化充分，6h即可出现担孢子，担孢子在适温适湿时，1h即可萌发，担孢子寿命暂短，活孢子传播距离近，百菌清等药剂喷杀锈孢子和松焦油柴油混液涂圆柏病部效果最好。     

山楂红色素的性质及提取工艺的试验

山楂色素为水溶性色素,其红色素为花青素类色素,稳定温度上限为50℃。山楂红色素提取最优条件为50℃,时间为4小时,物料配比为1:3;溶剂配比为36%HC10.1:95%乙醇100。     

山楂黄酮的薄层色谱分离鉴定研究

研究了山楂（山里红Crataegus pinnatifida Bge.var major N.E.Br)黄酮类化合物新的薄层色谱分离鉴定方法。以十二烷基硫酸钠-正丁醇-正庚烷-水微乳液为展开剂，利用聚酰胺薄层色谱法能使山楂黄酮完全分离。从山楂叶中分离得到7个黄酮斑点，山楂果中得到7个黄酮斑点，但二者的斑点不完全相同。与用正丁醇：乙酸：水4：1：5为展开剂的聚酰胺薄层色谱法比较发现，微乳薄层色谱法检测灵敏度高、分离效果理想。     

山楂红姑娘汁乳饮料的工艺研究

Comparison Study on Effects of Three Chinese Herbal Medicine on Intestinal Morphology in Weaning Piglets

The objective of this study was to compare the effect of three Chinese herbal medicine (medicated leaven, hawthorn, fructus hordei germinates) on histomorphology of different parts of small intestine in weaning piglets.40 28-day old ternary pigs (Duroc×Landrace×Yorkshire) with the body weight (8.13±1.32)kg were divided into four groups, control group, medicated leaven group, hawthorn group and fructus hordei germinates group, and feeding with 1% Chinese herbal medicine, there were two repeats in each group and each repeat had 5 piglets, slaughtering and sampling at 7th and 14th day morning, respectively, sections were used for HE staining.The staining tissues were taken pictures under a microscope camera (200×) and measured VH, CD, IWT and V/C in different parts of small intestine with Image-Pro Plus.The result showed that the IWH of ileum in medicated leaven group was significantly or extremely significantly higher than control group (P<0.05;P<0.01).The VH and IWT of duodenum and jejunum at 7th day in hawthorn group were extremely significantly lower than control group (P<0.01);The IWT of ileum and the VH of ileum at 14th day were extremely significantly higher than control group (P<0.01).In fructus hordei germinates group, the VH of duodenum and jejunum at 7th day and IWT of jejunum were extremely significantly lower than control group (P<0.01);The CD of ileum at 7th day, the IWT of duodenum and ileum at 7th day were extremely significantly higher than control group (P<0.01).The effects of different simple Chinese herbal medicine on histomorphology of different parts of small intestine in piglets were different, because of the different digestive functions of small intestine, the most effects of Chinese herbal medicine an duodenum, jejunum and ileum were fructus hordei germinates, medicated leaven and hawthorn, respectively.     

山楂栽培中常见的病虫害及防治

“山楂”与“花楸”源流辨考

《山楂树》这首歌译自原苏联歌曲《Уральскаярябинушка》。Pябинушка是рябина的爱称,而рябина则表示一种树名,拉丁名为Sorbus。中文本应是"花楸树",却错译成"山楂树"。山楂与花楸在我国古代就已种植,山楂始于上古,一直到中古、近代,种类多,异名也多;花楸约唐宋时期有文献记载,后世重要的农书、史书等也有记述,文学艺术典籍的用例少。现代,"山楂"是常用词,"花楸"是非常用词,常人对后者知之甚少。在俄罗斯,"花楸"是常用词,被赋予象征意义。已明"山楂"与"花楸"之源流,对俄文рябина应及时纠谬正之。     

紫外可见分光光度法测定注射用山楂总黄酮中总黄酮的含量

目的建立测定注射用山楂总黄酮中总黄酮的含量的方法。方法采用紫外可见分光光度法,检测波长为500nm,无水芦丁为对照品。结果芦丁在8.12~48.72μg/ml范围内呈良好的线性关系,r=0.9998(n=6),平均回收率为100.0%,RSD=0.13%(n=6)。结论所用方法灵敏、准确、重现性好、结果可靠,可用于注射用山楂总黄酮中总黄酮的含量测定。
