[Objective] Effects of nitrogen amount and nitrogen form on 1-deoxynojimycin（DNJ）content in mulberry leaf was explored in order to provide a reference for improving DNJ content in mulberry leaf and its medicinal value.[Method] Effects of nitrogen amount（NO-3-N and NH＋4-N）and nitrogen form（NO-3-N/NH＋4-N）on DNJ content in mulberry leaf were studied by changing nitrogen amount and nitrogen form in water culture solution.[Result] DNJ contents in mulberry leaf both increased at first and then decreased with the increase of nitrogen amount,furthermore compared with NH＋4-N,NO-3-N was more beneficial to the accumulation of DNJ;DNJ content in mulberry leaf obviously increased at first and then decreased with the decrease of NO-3-N/NH＋4-N,among them when its rate was 25/75,DNJ content reached the highest.[Conclusion] Proper nitrogen amount and nitrogen form could effectively improve the DNJ content in mulberry leaf.

The mulberry leaves have been considered as a sole food source for silkworm, Bombyx mori （L.）. In present work an attempt was made to investigate the role of low molecular weight peptide（s） isolated from mulberry leaves on silkworm rearing. Also we have tried to find out the role of free-radical scavenging activities of isolated peptide（s） on silkworm growth. Larval growth rate was found effective under the influence of peptide（s）. Consumption rate of larvae after peptide（s） treatment on mulberry leaves was significantly enhanced over control. High antioxidant activity was found in Low molecular weight peptide（s） which have an effect on silkworm.

2005年5月广西壮族自治区横县发生农户养殖的桑蚕食用桑叶后大批中毒死亡的案件,惊动全区。对桑叶进行毒物分析,结果表明桑叶中含有特丁硫磷农药。特丁硫磷常用作农田杀虫剂,其被桑叶吸附后,混合在叶绿素中,给分离工作带来困难。采用固相微萃取(SPME)顶空方法富集挥发性的特丁硫磷,直接注入色谱中,色谱分离后质谱测定,可检测出特丁硫磷农药,为案件的定性提供有力依据。案件侦破后,据嫌疑人交代系投放特丁硫磷农药。
