N2  - An experiment was conducted in the Department of Processing 
Technology, College of Horticulture, Vellanikkara during 2001-2002 to evolve a 
suitable drying regime for adhatoda and to find out the suitable packaging materials 
ideal to store the dried samples and hot water extracts with minimum quality 
deterioration. 
- 
Sun drying of the whole plant chopped into pieces was evolved as the best 
drying technique with respect to the quality attributes like vasicine content and 
alcohol as well as water soluble extracts for A. zeylanica and A. beddomei. Chopping 
of the whole plant helped in achieving faster drying. Roots of adhatoda also have 
sufficient quantity of medicinally active constituent vasicine. So uprooting the whole 
plant would be better than taking aerial cuttings alone. 
Sundried chopped pieces stored in 250 gauge polyethylene bags and 
powdered samples in steel containers had maximum retention of principal alkaloid 
vasicine after storage in room temperature for 5 months for both the species and the 
same samples also recorded the lowest microbial content whereas for hot water 
extract, glass bottles were more ideal than plastic bottles as it gave better shelf life, 
higher retention ofvasicine and lower microbial count. 
The technique thus developed can help to store the materials in a limited 
space for longer time without much spoilage or quality deterioration besides three 
times the quantity of dried whole plant could be accommodated when it is powdered 
and stored in rigid containers, additionally it adds convenience for the usage.
