Description
Technical Field
The invention belongs to the technical field of tea saponin and pesticides, and particularly relates to a modified tea saponin molluscicide and a preparation method thereof.
Background
Tea saponin is a natural plant molluscicide, is a pentacyclic triterpene saponin mixture, and mainly comprises aglycone, sugar body and organic acid. However, the unmodified tea saponin has insufficient molluscicidal activity, and particularly has a significantly lower molluscicidal effect on adult molluscs than young molluscs, and a large amount of tea saponin is needed to achieve the effective molluscicidal effect, so that the utilization efficiency of the tea saponin raw material is low. It is generally prepared in the form of a derivative in order to desirably enhance molluscicidal activity. For example, tea saponin is used as raw material to prepare effective molluscicide-spirowei. The molluscicidal effect of the spirocarb is remarkable, but the literature reports that the spirocarb has side effects including ecological damage of farmlands caused by toxicity and pesticide residue problems, such as certain damage effect on erythrocytes of fishes and shrimps.
Therefore, development of a novel tea saponin-based molluscicide is desired, which is low in toxicity and side effects while improving molluscicidal activity.
In addition, the structural modification of tea saponin is generally carried out by alkali hydrolysis and/or acid hydrolysis, and then the modification of groups is carried out, so that the physiological function of glycosyl is maintained, and when the structural modification is carried out, the hydroxyl on the glycosyl needs to be protected firstly, and then the structural modification is carried out. However, the protection and deprotection of the hydroxyl group are time-consuming and laborious, and increase the manufacturing cost, and there is still room for improvement in terms of industrialization. The inventors' prior patent CN202211592954.7 disclosed an esterification reaction of tea saponin in an ionic liquid with an organic acid in the presence of a condensing agent (a mixture containing a hydroxyphenylphosphine oxide derivative and an azodicarbonate). The method for synthesizing the tea saponin derivative is simple, effective and low in cost by utilizing the difference of the activities of the primary hydroxyl and the secondary hydroxyl and selectively carrying out esterification reaction on the primary hydroxyl of the tea saponin under the condition of not protecting the glycosyl dosage form. The invention is based on the research, and a novel modified tea saponin molluscicide is prepared according to the synthesis strategy.

Further, the modified tea saponin is prepared by a preparation method comprising the following steps: dissolving tea saponin in ionic liquid, adding pyrrolidone carboxylic acid and a photo-delay reaction reagent, and reacting for 2-3h at 130-150 ℃ under the protection of inert atmosphere and vacuum degree of 0.01-0.05 MPa.
Further, the molar ratio of pyrrolidone carboxylic acid to tea saponin is 2-2.2:1. the activity of the primary hydroxyl groups of the tea saponin is much higher than that of the secondary hydroxyl groups, the tea saponin contains 2 primary hydroxyl groups, pyrrolidone carboxylic acid with the molar weight of 2-2.2 times of that of the tea saponin is added, the 2 primary hydroxyl groups participate in the esterification reaction, and the secondary hydroxyl groups do not substantially participate in the reaction.
The light-delay reaction reagent is phenyl phosphine oxide derivative containing hydroxyl and azodicarboxylic acid ester according to the mol ratio of 1-1.2:1-1.2, wherein the dosage of the condensing agent is 1-3% of the mass of the tea saponin; the ionic liquid is imidazole ionic liquid and/or pyridine ionic liquid. Preferably, the hydroxyl-containing phenylphosphine oxide derivative is selected from at least one of bis (4-hydroxyphenyl) phenylphosphine oxide, tris (4-hydroxyphenyl) phosphine oxide, bis (4-hydroxyphenyl) (1-naphthyl) phosphine oxide, bis (1-naphthyl) (4-hydroxyphenyl) phosphine oxide, bis (4-phenoxyphenyl) (4-hydroxyphenyl) phosphine oxide, bis (4-hydroxyphenyl) (2, 4, 5-trimethylphenyl) phosphine oxide; the azodicarboxylic acid ester is at least one selected from dimethyl azodicarboxylate, diethyl azodicarboxylate, dimethyl azodiisobutyrate and diisopropyl azodicarboxylate.

Application example 1 molluscicidal Activity experiment
(1) The Poyang county is filled with the strong-activity oncomelania to form the snail for standby.
(2) The molluscicides of the above examples and comparative examples were diluted to 5mg/mL (low dose), 10mg/m (high dose) with dechlorinated tap water.
3) Under the room temperature condition, 50 snails are grouped into a group by adopting a snail immersing method, and are respectively immersed into 3000mL of the low-dose and high-dose molluscicide liquid for 24 hours and 48 hours, and are fished out for flushing by clear water, and the death rate of the snails is tested by adopting a knocking method. Clear water was used as a blank control group and 45% of baipirocin was used as a positive control group. The results are shown in Table 1 below.
Table 1 test of molluscicide activity against oncomelania
As can be seen from the data in Table 1, the modified tea saponin molluscicide provided by the invention has very excellent molluscicide activity, the death rate of 24 hours reaches more than 80% and the death rate of 48 hours reaches more than 90% under the low dosage concentration of 5mg/mL, and the death rates of 24 hours and 48 hours of a negative control group (clear water) are respectively 0% and 4%. At high dosage, the death rate of the modified tea saponin molluscicide disclosed by the embodiment of the invention reaches 100%. And compared with the positive control group, the molluscicidal activity is higher than that of the hundred molluscicides.
In addition, the inventor also discovers that the modified tea saponin molluscicide prepared by taking the combination of the anionic surfactant and the nonionic surfactant as a dispersing agent has the optimal effect.
Unmodified tea saponin has low toxicity to prawns and is often used in shrimp ponds, but even at very dilute concentrations, it has greater toxicity to fish. The half lethal dose of tea saponin to Ding Ban fish is 3.8mg/L, and the half lethal dose of the modified tea saponin obtained in preparation example 1 of the invention to Ding Ban fish is 18.7mg/L. The reason is presumably that the modified tea saponin has reduced permeability to fish red blood cells. The tea saponin modified by pyrrolidone carboxylic acid esterification improves molluscicidal activity and reduces toxicity to fish. The device is more suitable for killing snails in farmlands, and cannot cause pollution or harm.
