Abstract: Medicinal plants are rich source of secondary metabolites, biosynthetically derived from primary metabolites but restricted to specific taxonomic genera of plant kingdom and specific parts of plant. Based on experimental result 1% and 5% concentration of TZ salt with 18 and 24-hour incubation period shows high colour intensity of foramen. 92% seed viability shown in seeds of Trichosanthus.98 % seed viability shown in seed of Embelia. Colour intensity of foramen on Embelia seeds was high, that treated with 1%, and 0.5% TZ solution for 18 and 24 hour incubation period. Best treatment for viability test for Indriyas in 1% TZ solution with 18-hour incubation period with 30-35 °C temperature. 24-hour fan dried seeds reduced their moisture content up 17.59% while one day sun dried and three day sun dried seeds reduced their moisture content up to 16.07% and 14.22% respectively. Fresh seed moisture content of Trichosanthes tricuspidata data was 16.67%. Dried seeds by silica gel reduced seed moisture content up to 9.01%, while 7 days sun dried and 15 days natural air dried seed lots reduced their moisture content up to 8.02 and 10.5 respectively. Thousand seed weight of Indriyas is 234.8gm, whereas 1000 seed weight of barbering 6.048gm. 1000 seed weight is helpful for determination of submitted and working seed sample size from a seed lot.
