实验研究海藻体中二甲基硫基丙酸酯（Ｄｉｍｅｔｈｙｌｓｕｌｆｏｎｉｕｍｐｒｏｐｉｏｎａｔｅ，ＤＭＳＰ）的简单测定方法。改进顶空进样方法灵敏度低的缺点，采用碱解和萃取吸收同时进行气相色谱火焰光度检测法测定不同种类的底栖藻中所含的ＤＭＳＰ。并以此测定不同季节胶州湾部分地区近岸表层水体浮游藻所含的ＤＭＳＰ，同时还测定水体中的磷酸盐浓度。结果表明在底栖藻中ＤＭＳＰ含量随季节呈现一定的规律性变化，不同藻体内ＤＭＳＰ含量相差可达两个数量级，而单位水体微藻中的ＤＭ－ＳＰ亦随季节呈现一定的规律性变化
An Experimental Study on the Simple Determination of Dimethylsulfoniumpropionate (DMSP) in Seaweed. Improving the low sensitivity of headspace injection method, using alkaline hydrolysis and extraction absorption gas chromatography flame photometric detection of different species of benthic algae contained in the DMSP. The DMSP contained in the phytoplankton in the surface water near the shore of Jiaozhou Bay in different seasons was also measured to determine the phosphate concentration in the water. The results showed that the contents of DMSP in benthic algae changed regularly with the seasons. The difference of DMSP content in different algae was up to two orders of magnitude, while the DM-SP in microalgae of the water body also showed some regular changes
