查询词典 leaf

The leaf epidermis structures of 6 species of Rhododendron had been observed under LM and SEM. The results show that all share together common features as follows: the leaf blades are typical back-abdomen bifacial types, the upper epidermis are formed by two or three layer bigger cells which inside layer cell is bigger than outside one, and the upper epidermis are covered with thicker cuticle.

Extracts with higher antioxidant abilities, including hot water and ethanol extracts of Boehmeria nivea leaves and roots, were screened and then added into soy bean oil to study effects on oil stabilities of oxidation during storage and also to develop new XO paste products containing Boehmeria nivea leaves and roots. The extents of oil oxidation in XO paste were evaluated by measuring POV and TBA values. Results indicated that after 8 day storage at 70℃, the POV values of soy bean oil with addition of 0.1% of ethanol extracts of leaf and root were 56.27± 0.12 meq/kg and 57.13± 0.50 meq/kg respectively, which were both greater than that of control samples(53.33 ±0.31 meq/kg), showing that extracts of leaf and root do not have the abilities to inhibit oxidation of soy bean oil.

第二部分将抗氧化能力较高的萃取物，包括苎麻叶与根的热水及乙醇萃取物添加於大豆油中，探讨其对油脂贮藏安定性之影响及开发加入苎麻叶或根的XO酱产品，并藉由测定油脂中过氧化价(peroxide value，POV)和硫巴比妥酸值(thiobar-bituric acid value，TBA)值评估其油脂氧化程度，结果贮存在70℃下第8天时，添加0.1 %苎麻叶与根乙醇萃取物，其POV值分别为56.27±0.12 meq/kg与57.13±0.50 meq/kg，皆较对照组(53.33 ±0.31 meq/kg)高，显示以0.1 %的苎麻叶和根萃取物添加大豆油中并不具抑制油脂氧化作用。

The first part of this research was to investigate anti-oxidant abilities of Boehmeria nivea leaf and root. Different extraction methods, drying conditions as well as far infrared were applied to measure their effects on anti-oxidant abilities of Boehmeria nivea leaf and root. Results showed that 95% ethanol extracts of fresh leaves and roots demonstrate the highest anti-oxidant components(total contents of phenol compounds and flavonoids)and scavenging abilities free radical scavengingABTS(2,2'-azinobis［3-ethylbenzothiazoline-6- sulfonic acid］and DPPH (α,α-diphenyl-β-picrylhydrazyl) free radical , followed by hot water and cold water extraction.

本研究第一部份拟针对苎麻叶与根探讨其抗氧化能力，并以不同萃取方法、不同乾燥处理方式及经远红外线照射对其抗氧化能力之影响，研究结果显示，在不同萃取方法中，新鲜苎麻叶与根皆以95%乙醇萃取物的抗氧化成分及抗氧化能力清除ABTS(2，2'-azinobis［3-ethylben-zothiazo-line-6

Bracteal leaf, subtending leaf

In order to find out the active components, the analysis on chemical composition of the leaf from Broussonetia papyrifera uangyechu through the technology of test tube and paper chromatography were accomplished. The results showed that the leaf contains phenols, amino acids, proteins, polypeptides, saponins, flavonoids and its saponins, sterols, and triterpenes.

为研究光叶楮叶中的化学成分，采用试管法和圆形滤纸层析法对其进行测定，结果表明：光叶楮叶片含有酚性成分、氨基酸、蛋白质、多肽、皂苷、黄酮及其苷类、植物甾醇、三萜等多种化学成分。

Tea picking is usually only take tender referred to as the "lotus"; one and a bud, like the flag leaf, shoot like guns, are referred to as the "flag of the gun"; one bud two leaves, leaf curl, the shape of Buxus, so that "Buxus."
