Sr. no.	Method	Advantages	Disadvantages
1	Conventional Extraction	The method has been tested initially.	Long extraction time, using a lot of solvents, acids and bases resulted in the degradation of polysaccharide
2	Microwave-Assisted Extraction (MAE)	Short extraction time with a relatively small amount of solvent.	High heat causes the degradation of polyphenols.
3	Ultrasound-Assisted Extraction (UAE)	The extraction time is short. The method works at low temperatures using a relatively little solvent.	Degradation and changes in the structure of polysaccharides.
4	Supercritical Fluid Extraction (SFE)	CO was removed from the extract easily and did not cause structural degradation of the compound.	High pressure to retain solvent which hurts the compound.
5	Pressurized Solvent Extraction (PSE)	The method is similar to Soxhlet extraction, but the solvent has high extraction properties.	The combination of high temperature and pressure to increase the solubility and diffusion of the solvent is difficult.
6	Enzyme-Assisted Extraction (EAE)	Does not use organic solvents but high yield. Extraction results depend on the time, pH, and enzyme temperature. Efficiency depends on the nature of the enzyme.
