References

CHE

Soxhlet apparatus

3.2%

2 h

95% Ethanol,10% aq. Potassium hydroxide

Simple, low cost, no filtration is required after leaching

A long time of extraction and a large amount of extractant is required

Luque de Castro and Priego-Capote [175], Shingate et al. [25]

Reflux Extraction

RBF, condenser,

Buchner funnel, etc.

5%

20 min

Dichloro-methane,

Acetone and Hexane

More efficient than percolation or maceration and requires less extraction time and solvent

Cannot be used for thermolabile natural products

Shingate et al. [25], Zhang et al. [176]

Cold Maceration

Separating funnel, Rota evaporator, etc.

4.6%

–

GAA, chloroform,

10% sodium bicarbonate, toluene, ethyl acetate, sodium hydroxide, diethyl ether

Yield is high, pure, and crystallizable as compared to the above two methods

Complex and time-consuming

Extraction

SPEED

SFE 2, Ice-bath

0.88–1.38 mg/g dry black pepper

2.25 h

α-Amylase, CO2, methanol

Efficient

Expensive

–

0.58% w/w

18 min

Ethanol, hexane, and acetone

Short running time, higher extractive yield, controllable parameters

Small particle size, more filtration steps

Shityakov et al. [183]

SFE

–

90–96% w/w

2–5 h

Liquid carbon dioxide

Efficient, selective, clean, fast

High cost, less pressure-resistant
