Results and discussion

Any other information on results incl. tables

Following a preliminary analysis, the AISI crucible was employed to investigate in detail the various changes which occurred on heating to the sample.

The AISI type of crucible is suitable for the accurate determination of melting transition up to. The test was then performed with an AISI crucible in a temperature rangefrom 30 towith a heating rate of 5°C/min.

 

The following behaviour was noted.

130 - 145°C  an endothermicdeparture showing a probable melting transition of the main component present in the test article

145 - 300°C  the baseline increased and became unstable showing a probable non homogeneous decomposition phenomena

Applicant's summary and conclusion

Conclusions:

It is not possible to obtain a well defined boiling point for Sesbania Grandiflora Dry Purified Extract sample; a melting transition of the main component was detected from 130 to 145 °C, followed to probable concurrent decomposition phenomena.
