1.0 Summary
The solid-liquid extraction of Ganoderma Lucidum is carried out to in order understand the different techniques utilized. Furthermore, it is used to understand the effects of various physical factors on the level of extraction.

An intense literature research was carried out on the specimen itself to understand its sources, bioactive constituents, growth and cultivation and medical properties. The basic meaning of the term solid-liquid extraction (SLE) is identified and the basic factors affecting is rate are outlined to be particle size, solvent, temperature and agitation.

The methods of SLE utilized in the
experimental procedure are (i) conventional- hot plate magnetic stirrer method and non conventional (ii) ultra-sound bath and (iii) ultra sound probe method. The underlying theory of the conventional method is that SLE is favored for increasing temperatures and longer agitation periods. Moreover, for the non-conventional methods, the mechanism of ultrasound radiation in a liquid medium is understood, outlining clearly the meaning and uses of micro -bubble cavitation. The mechanism by which the SLE extraction occurs when subjected to ultrasoun d radiation is found. The advantages of using ultra-sound assisted extraction equipment as opposed to conventional SLE methods are identified. Although non-conventional ultra-sound equipment is more effective, they are expensive thus their applicability for SLE is reduced. For each piece of equipment, the working mechanism is identified in relation to...
