에틸렌 발생 tablet 제조 및 활성 최적 조건 구명

초록

Ethylene (C2H4) is a naturally occurring hormone in some fruit. This study was carried out to manufacture ethylene-producing tablets. The Ethylene-producing tablets were manufactured from ethephon and excipient mixtures, including Prosolv, Hydroxypropylmethylcellulose (HPMC) and Crosscamellose. Ethylene production increased with the increases in temperature. In the aspect of pH condition, ethylene productions at pH 7.0 and pH 9.0 were less than 2 ppm. On the other hand, at pH 13.0, ethylene production from the Prosolv, HPMC, and Crosscamellose tablets was 94.05, 126.28, and 100.11 ppm, respectively. The friability of the Prosolv and HPMC tablets were 0.1 and 0.3%, respectively, while the Crosscamellose tablet was 54.1%. indicating that the Crosscarmellose tablet was not appropriate as an ethylene production tablet. In addition, there were huge variations in disintegration times; the Prosolv, Crosscamelose, and HPMC tablets took 1, 5 min, and 7 min more than respectively. Ethylene production was gradually increased up to 20 hr for the Prosolv tablet and then remained stable.
