The hydrolysis of birchwood xylan yielded mainly xylobiose and xylotriose, no xylose was detected by TLC. Therefore, XynA may be suitable for production of xylooligosaccharides.

XynA水解桦木木聚糖的主要产物为木二糖和木三糖，无木糖生成，说明它适合应用于低聚木糖的生产。

Chemical modification of the xylanase with NBS and WRK revealed that trytophan and glutamate/aspartate were essential for the activity. 3.0 mgmL^(-1) birchwood xylan could completely inhibit the inactivation of xylanase by NBS.

木聚糖对NBS的修饰有抑制作用，3.0mgmL^(-1)的桦木木聚糖底物可完全阻止NBS对耐热木聚糖酶的修饰作用，但木聚糖底物不能阻止WRK对耐热木聚糖酶的失活作用。

Thin-layer chromatography analysis showed that the xylanase released mainly xylobiose and xylotriose from birchwood xylan. The hydrolysis of xylotriose appeared to proceed via transglycosylation, since the xylobiose was the predominant product.

薄层层析结果显示该酶水解桦木木聚糖的主要产物是木二糖和木三糖，并且能够通过转糖苷作用将木三糖转化为木二糖。

The effects of extraction temperature, microwave power, extraction time on betulin yield by MAE were discussed and the betulin content was determined by HPLC.

考察了提取温度、微波功率、提取时间对桦木醇收率的影响，并用高效液相色谱法测定了萃取物中桦木醇的含量。

Betulin and betulinic acid , the triterpenes of the lupane family, are considered to be potential agents against tumoral cancer and HIV .

桦木醇、桦木酸是具有羽扇烷结构的三萜化合物，目前的研究发现，它们具有较高的抗肿瘤、抗HIV病毒活性，它们的衍生物也有较高的生物活性。

Its structure was characterized by FT-IR, 1H NMR and MS. Solubility data of betulin and 3, 28-di-O-glutaryl-betulin in acetone, ethanol, water and phosphate-buffered saline (PBS, pH value 7.4) were determined by equilibrium method.

采用FT-IR、1H NMR和MS对产物进行结构表征，并且选用平衡法测定了桦木醇和桦木醇戊二酸酯在丙酮、无水乙醇、水和磷酸盐缓冲溶液（PBS， pH值7.4，）等不同溶剂中的溶解度。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
