Abstract :

Variations in chemical composition of propolis may also affect its melting point The melting point of propolis samples collected in Srinagar (J&K) from different colonies, irrespective of period of collection varied between 81.04 to 83.05OC and Samples collected in Coimbatore (TN) varied between81.92 to 86.63OC. Variations were also observed during different month from two different years. The melting point was 76.00OC of the samples from Srinagar collected in April and 81.31OC of the samples collected from Coimbatore likewise samples collected during March shows melting points 92.44 and 92.90 from two respective places. Such variations may be due to different sources of resin and type of impurities in the propolis samplessolubility of propolis in 70% alcohol was more in the samples collected from Srinagar 45.79 to 47.93% and Coimbatore 47.05 to 49.26% using 18 and 26 mesh nylon nets respectively Compared to other traps 33.44 to 39.29 in Srinagar and 34.46 to 40.49 in Coimbatore which is indication of the effect of trapping method on the composition of propolis The solubility of propolis was same whether extracted for 10 or 17 days.
