- Maceration
- Solvent + 3 days + RT
- Solvent + 3 days + RT
- Percolation
- Maceration + Continous Fresh solvent Flow
- Maceration + Continous Fresh solvent Flow
- Digestion
- Maceration + Gentle Heat
- Maceration + Gentle Heat
- Infusion
- Maceration short time
- Readily Soluble Cpds
- Readily Soluble Cpds
- Maceration short time
- Decoction
- Boiling for 15'
- Thermostable Cpds
- Thermostable Cpds
- Boiling for 15'
- Continous HOT extraction Using Soxhlet Extractor
- P.M is repeatedly extracted with solvent & the dissolved const. are conc. In the extraction flask
- Thermostable Cpds & If Thermoliable use Low B.P solvent
- Thermostable Cpds & If Thermoliable use Low B.P solvent
- P.M is repeatedly extracted with solvent & the dissolved const. are conc. In the extraction flask
- UAE
- Ultrasonic Energy + Pressure
- High Temp = Inc. Solubility & Diffusion of Const. in solvent
- The oxidative energy from radicals Created during the
process Inc. Extraction Power
- If Pressure is Applied inc. Penetration &
Transport Between Solvent & P.M
- If Pressure is Applied inc. Penetration &
Transport Between Solvent & P.M
- The oxidative energy from radicals Created during the
process Inc. Extraction Power
- High Temp = Inc. Solubility & Diffusion of Const. in solvent
- Ultrasonic Energy + Pressure
- MAE
- Microwaves --> Agitation + Heat Energy
- If Pressure is Applied inc.
Penetration & Transport Between
Solvent & P.M
- If Pressure is Applied inc.
Penetration & Transport Between
Solvent & P.M
- Microwaves --> Agitation + Heat Energy
- PLE
- Extraction with Liquid solvent under High Temp Inc.
Diffusion Rate & Solubility & High Pressure Keep
solvent Below B.P
- Extraction with Liquid solvent under High Temp Inc.
Diffusion Rate & Solubility & High Pressure Keep
solvent Below B.P
- SFE
- Carbondioxide Gas Under Critical Temp. = Gas--> Liquid
- Available & cheap Inert Non-toxic Non-inflammable Easy to
eliminate Has low critical temp. ( 31o C at P= 74 bar )

- Carbondioxide Gas Under Critical Temp. = Gas--> Liquid
- SPE
- Solid phase pre-packed in column = stationary phase + solvent
- to isolate / purify a sub or sample of interest from a more
complex sample Eg: Before analysis of Biological samples

- SPME
- Analysis of some V.O containing drugs In GC & LC Analysis of Dilute
samples in both gaseous & Liquid states Adsorptive phase : silicone
Fibers
