摘 要：
以肉果秤锤树核果为试材,以白菜籽为研究对象,运用系统溶剂法提取分离肉果秤锤树(Sinojackia sarcocarpaL.Q.Luo)核果甲醇浸提液,得到石油醚相、乙醚相、乙酸乙酯相、甲醇相4个分离组分,进行发芽抑制物质生物测定,并对各个萃取液组分进行鉴定和相对含量测定,进一步研究了肉果秤锤树核果内源抑制物与种子休眠的关系。结果表明:乙醚相、乙酸乙酯相、甲醇相中含有抑制种子萌发和幼苗生长的物质,且含有的抑制物活性依次为:甲醇相>乙酸乙酯相>乙醚相。通过气相色谱-质谱联用仪进一步分离与鉴定,确定发芽抑制物的种类与相对含量,发现肉果秤锤树核果中包含辛酸、十七烷酸、油酸等发芽抑制物。

摘 要：
Taking Sinojackia sarcocarpaL.Q.Luo drupe as materials,and seeds of Chinese cabbage as research object,by the use of systematic solvent extraction method,four kinds of organic phase were got from the Sinojackia sarcocarpaL.Q.Luo drupe methanol extract,which were petroleum ether phase,ether phase,ethyl acetate phase and methanol phase.Biological test of germination inhibitor was conducted,component identification and relative content of each organic phase were determined.The results showed that inhibition of seeds germination and seedling growth substances exist in ether phase,ethyl acetate phase and methanol phase,and the inhibitory viabilities among them were as follows.Ether phase
