In this process,phenolic compounds such as caffeic acid and tannin are extracted from a water fern called azolla mycrophylla, this plant does not have seed or flowers.Both these acids have immense potenial roles Caffeic acid as an antioxidant,anticarcinogenic as well as anti-inflammatory while tannin has been used to treat various diseases along with acting as a shield from external attackers like predators in plants.The extraction procedure started from the crushing of the dried azolla plant material converting it into powderous form so as to mix it with a solvent such as petroleum ether instead of ethanol for further mixing and then it is placed inside a UV sonicator before filteration using a funnel and filter papaer for removal of the plant debris,after using a seperating funnel for seperation it is placed in a rotary evaporator so that the solute and solvent gets seperated as the solvent that had been initially used is seperated out along with drying of the rest of the material which can be further used for the analysis of caffeic acid as well as tannin and for their further analysis using aspectrophotometer.Spectrophotometer analysis gave the exact peaks at the particular wavelengths.These acids have olso
