I am using plant extracts to study their phytoconstituents showing antimicrobial activity.
Hydroethanolic or methanol extraction / decoction may help. Then follow by freeze drying to obtain the extracts
This is an ”involved” question. The method to be employed would depend on the class of natural products to be isolated. Some procedures utilized: mace ration, radiation and ultrasound associated extraction. Solvents used: polar (water; alcohol), intermediate polar (acetone), nonpolar (n-hexane). Polyvinyl pyrrolidone is useful in extracting polyphenols, in particular....
Solven extraction, specifically water because of polarity of water to extract both polar and nonpolar phytochemicals
pour mieux identifier les composés, c'est la macération à froid qui mieux
Hydroethanol (30:70) at 400C, assisted by shaking and or microwave assisted for total extractions.
ethanolic extract and aqueous extract. They give you an excellent result.
i am used to them
