The total contents of phenol compounds of fresh Boehmeria nivea root was 200.24± 0.93 mg/g, which is 4.5 times higher than ethanol extracts of fresh Boehmeria nivea leaf, and its ability to remove ABTS free radical is 7.4 times higher than that of fresh Boehmeria nivea leaf, which is one third of Trolox's ability to remove free radical. Antioxidant components of hot water extracts of Boehmeria nivea leaf exhibited 55 and 67% lower than that of fresh leaf respectively.

sulfonic acid］和DPPH(α，α-diphenyl-β-picrylhydrazyl)自由基为最高，其次为热水萃取物和冷水萃取物，而新鲜苎麻根乙醇萃取物总酚类含量为200.24 ±0.93 mg/g，约高於新鲜苎麻叶乙醇萃取物的4.5倍，其清除ABTS自由基能力是新鲜苎麻叶乙醇萃取物的7.4倍，约为维生素衍生物的1/3倍。

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.
