ABSTRACT

Samskara is an important concept led by ancient Ayurveda scholars and is defined as transformation (Samskaro hi Gunantaradhanam uchyate) of the inherent attributes (Swabhavika Guna) of a substance which leads to the addition of new properties. Bhavana is an important Samskara with the help of which, not only the potency of a drug can be altered, but is also capable to bring about changes in characteristics of drug viz. regulation, addition of new or deletion of undesirable characteristics. Bhavana is a unique pharmaceutical process in which a drug or mixture of drugs in powdered form is triturated with sufficient quantity of liquid media (swarasa, kwatha, etc. or animal products like milk, urine, etc.) till liquid portion gets absorbed completely. Bhavana facilitates in mixing of ingredients of mixture for Bhavana and may account several chemical interactions in between them. The changes made by Bhavana in nature of drug can be preliminarily and easily perceived at pharmacognostic as well as chemical level; however its utility will be majorly dependent on therapeutic actions. Thus, it plays a pivotal role in the alteration of Gunas (properties) of drugs so as to fulfill therapeutic requirements. Above change cause alteration in the sensory perception of the drug as well as it also alter visual perception of the drug as whole. During the process of manufacturing colour perception play major role to take decision of completion of process. L*a*b colour space is considered as very near to human visual perception. Hence the study was designed to trace out scope of visual perception discrimination using regular expression of L*a*b colour segmentation protocol of MATLAB on drug Palasha beeja churna and its Bhavita samples. In conclusion observed that the colour segment of raw drug is modulated to different colour space when exposed to Amlaki swarasa but exposure of Ajadugdha generate pool to ward green colour space, over and above sequential exposure of same material (vehical) shows different selectivity of chemical modulation hence resultant it shows different colour space in every bhavana completion. The colour space shows scope in SOP of drug production line up for consistence drug manufacturing.
