Novel application of salicornia europaea and root extractive thereof

Abstract

The invention discloses novel application of salicornia europaea and a root extractive thereof. The salicornia europae (Salicornia europaea L.) and the root extractive thereof provided by the invention are used for inhibiting the algae growth causing red tide and inhibiting the red tide. The algae causing the red tide is selected from at least one of skeletonema costatum, prorocentrum donghaiense and prorocentrum minimum. The method for preparing the root extractive of the salicornia europae comprises the following steps: using an organic solvent as an extractant, and extracting from the root of the salicornia europaea, wherein the organic solvent is selected from any one of petroleum ether, chloroform, methanol and normal butanol. The result of the test shows that four different root extractives of the salicornia europaea can strongly inhibit the growth and the photosynthesis of three kinds of algae; for different algae, the allelopathy strength is different; for the skeletonema costatum, the allelopathy of the petroleum ether phase extractive is the strongest, and IC50 is 1.633 mg / L; for the prorocentrum donghaiense, the function of the chloroform phase extractive is the strongest, and IC50 is 13. 799 mg / L; and for the prorocentrum minimum, the allelopathy is improved along with the increasing of the polarity of the extractive, the function of the methanol phase is the strongest, and IC50 is 1.138 mg / L.

Description

technical field [0001] The invention relates to a new application of salt hornwort and its root system extract. Background technique [0002] Red tide is one of the marine environmental problems that the international community is concerned about and urgently needs to be resolved. Since the 1990s, the occurrence of red tides in my country has shown the characteristics of "large-scale, high-frequency, multiple types, and fast-paced", which poses a great threat to the ecological environment of coastal waters and the sustainable development of aquaculture, and at the same time endangers tourism. industrial development and human health. Adopting effective red tide control measures is one of the important contents of red tide research. Scholars at home and abroad have proposed including using loess, clay, copper sulfate and some biological agents like bacteria and viruses to control red tide. While these approaches may be effective in the short term, they can cause varying degr...

Problems solved by technology

The current reports on Salicornia mainly focus on its salt tolerance and salt tolerance mechanism (Ushakova, S.A., N.P.Kovaleva, et al.(2005).Advances in Space Research 36(7):1349-1353.), Ozawa et al. (Ozawa, T., M.Miura, et al. (2007).Plant and Cell Physiology 48:S242-S242.) found that Salicornia can tolerate and accumulate heavy metals, but never saw the relevant chemistry of Salicornia role, especially interactions with marine organisms
