The Shelf-life of Agricultural Organic Materials Containing Cinnamon or Derris Extract: Thermal Stability of Cinnamyl Derivatives and Rotenoids

Abstract

. The selected bioactive compounds were cinnamaldehyde, and cinnamyl alchol in cinnamon extract and deguelin, and rotenone in derris extract. Half-lives of the total cinnamyl derivatives in biopesticide (A, B, C, and D) ranged from 15.1 to 46.2 days on the different temperature and cinnamaldehyde was more stable than cinnamyl alcohol in the biopesticide. The half-lives of total rotenoid ranged from 1.7 to 173 days on the different temperature in the tested biopesticide (E, F, and G) containing derris extract. The stabilities of deguelin, and rotenon in the biopesticide showed similar values in the same condition.
