What is the best solvent for the extraction of chemical compounds that have an insecticidal effect ?
Dear Rouari - In order to suggest to yo the most suitable solvent it is essential to know what type of compounds you want to extract. It is particularly important to know the polarity of the insecticidal compound so that an organic solvent with similar polarity can be chosen.
However, To give you some initial ideas, Please see this potentially useful article entitled "Extraction, Purification and Characterisation of Insecticidal Compounds from Plants". In this paper "the different techniques involved in the extraction, purification and characterization of insecticidal compounds extracted from plants along with some salient examples available in the literature are discussed." The article is available as public full text on RG:

First of all, you must know the type of compounds you want to extract and according to their nature, you can define which will be the best method and type of solvent to use.
The phytoconstituents can be extracted based on their chemical nature so according to me first you need to determine the chemical nature of your targeted phytoconstituents and then you need to decide solvent. You can decide your solvent on the basis of polarity chart also.

Dear Rouari Linda you're very welcome. I hope it was useful. Please let us know if you need any more specific informations (e.g. certain classes of insecticides).
it depends to the nature of each compound.firstly, you must to determine this compounds so you can choose a solvent.
Dear Rouari Linda in the following paper which is entitled "Evaluation of Two Different Solvents for Azolla pinnata Extracts on Chemical Compositions and Larvicidal Activity against Aedes albopictus (Diptera: Culicidae)" the solvents methanol and acetone are compared.

Dr. Frank T. Edelmann is one of the experts on any problem related to chemistry, I guess.
Dear Tanvir Singh many thanks indeed for your kind words and compliment. I think it's just my experience of 40+ years in chemical research. Since our main field of research is organometallic chemistry, we have expertise in both inorganic and organic chemistry. All the best, Frank Edelmann
