The rapid propagation of Eichhornia crassipes has a threatening impact on the aquatic environment. For most small water areas with good ecology, daily manual monitoring and salvage require considerable financial material resources. Unmanned boats have important practical significance for automatic cleaning crassipes. To ensure that target can be accurately detected, we solve problems exist in l...

Waterhyacinth is one of the fastest growing plants which disrupt the ecological balance. The plant inspite of its obnoxious nature, is a source of various pharmacologically active compounds. Sterols were isolated from the ethyl acetate extract of waterhyacinth and characterized to be a mixture of stigmasterol and β-sitosterol based on UV, IR, 1D and 2D NMR studies. Quantification of the isolate...

In October 2012, in a survey in order to study the flora of paddy fields and aquatic ecosystems of Gilan province (N Iran), we encountered an unknown species in “Aynak lagoon” in southeast of Rasht, covered surface of about 12 ha pond densely. Comparing the flora of pond with previous years or adjacent ponds showed that, the new weed was dominant in interference with natural flora of aquatic ec...

Water hyacinth is undoubtedly an environmental problem due to its invasiveness, but it also has some promising futures. It might be preferable consider the specific attributes of each environment where plant grows. When there are facilities available fully utilize this plant's potential, efforts should focused on maximizing growth. been shown that secondary metabolites, such as phenolic and ant...
