The highest total flavonoid rate was 1.127%. An all-round evaluation for the antioxidant activity of the flavonoids extract from zizania-bract was carried out with that of ascorbic acid as the control. The evaluation indexes included the cleanup rate of the polyphenolic extract towards superoxidized anionic radicals, hydroxyl radicals, DPPH free radicals, the deoxidizing ability, and the antioxidant activity towards the peroxidize of lipids and edible oils.

采用抗坏血酸作为对照，全面测定了茭白苞叶总黄酮对超氧阴离子自由基、羟基自由基、DPPH自由基的清除率，以及还原能力、抗脂质过氧化活性和对食用油脂的抗氧化性的影响，结果表明，白苞叶中的总黄酮是一种有开发价值的天然抗氧化剂。

模型中综合考虑了温度、水分及呼吸作用对植被净第一性生产力的影响，由植被指数确定植被对光合有效辐射的吸收比例，由光能转化率计算植被总第一性生产力，由总第一性生产力与呼吸消耗之间的差值确定净第一性生产力。

In addition, a pre-column derivatization HPLC method was applied to the determination of Astragaloside Ⅳ; the flavonoids was determined by full-range HPLC scanning; a colorimetric method was developed for the determination of flavonoids and saponins. Hierarchical cluster analysis was performed on three constituents of different Radix Astragali species, and its result was compared with those of traditional phytoecological identification and the pharmacological quality assessment.

本研究以比色法测定了黄芪中总皂苷的含量，以柱前衍生化高效液相色谱法测定了黄芪中黄芪甲苷的含量；以比色法测定了黄芪中总黄酮成分的含量，以反相高效液相色谱法测定了黄芪中毛蕊异黄酮和毛蕊异黄酮苷的含量；以黄芪中的黄芪甲苷、毛蕊异黄酮和毛蕊异黄酮苷为主要特征对不同品种的黄芪进行了系统聚类分析，并将聚类结果与传统生药学鉴定和药理质量评价结果进行了比较。

The lumped kinetic model of monoterpene, abietic type resin acid, pimaric acid type resin acid, p-cymene, hydro-monoterpene, dehydro-abietic acid, hydro-abietic type resin acid, and hydro-pimaric acid type resin acid was established based on the structural groups and approximate reaction kinetic theory according to the fundamental principles of the lumped method.

在消除内、外扩散影响的条件下，在线跟踪反应产物并用气相色谱法测定反应体系组成随时间的变化，构造了Pd／C催化剂上松脂分子间氢转移集总反应网络，建立了包含单萜烯、枞酸型树脂酸、海松酸型树脂酸、对伞花烃、氢化单萜烯、脱氢枞酸、氢化枞酸型树脂酸和氢化海松酸型树脂酸等复杂反应体系的集总动力学模型，并估算了模型参数。
