The volatile oils of Arundo donax Linn (giant reed) were extracted by two methods, one was Water-steam distillation, the other was petroleum extraction and then fractionated with some chemical reagent. Components of the volatile oils were analyzed and identified by gas chromatograph-mass spectrometry (GC-MS), and the allelopathic effect of the volatile oils were also explored by bioassay of Microcystin...
The study of community composition of algae is essential for understanding the structure and dynamics of the aquatic ecosystem and for evaluating the eutrophic level of the water body. A high-performance liquid chromatographic (HPLC) method based on a reversephase C18 nonpolar column was developed for the main algal taxa, which includes cyanophytes, bacillariophytes, euglenophytes, dinophytes, and...
The volatile oils were extracted from Typha latifolia by Water-steam distillation. Components of the volatile oils were analyzed and identified by gas chromatograph-mass spectrometry (GC-MS), and the allelopathic effect of the volatile oils were also explored by bioassay of Microcystin aeruginosa. The results showed that the volatile oils had activity to inhibit the growth of M. aeruginosa. This study...
