Pengembangan dan Evaluasi Stabilitas Formulasi Gel yang Mengandung Etil p-metoksisinamat Nelly Suryani; Deani Nurul Mubarika; Ismiarni Komala
Pharmaceutical and Biomedical Sciences Journal (PBSJ) Vol 1, No 1 (2019)
Publisher : UIN Syarif Hidayatullah Jakarta

Etil p-metoksisinamat (EPMS) merupakan senyawa utama aktif anti-inflamasi yang terdapat dalam rimpang kencur (Kaempferia galanga). Tujuan penelitian ini adalah untuk mengembangkan sediaan gel yang mengandung EPMS dengan menggunakan kombinasi HPMC dan karbopol 940 sebagai gelling agent. Sediaan gel di buat dalam tiga formula F1, F2 dan F3 dengan variasi persentase kombinasi HPMC : karbopol 940 yang digunakan masing-masingnya adalah 0,4 : 0,4%, 0,5 : 0,5%, dan 1.0 : 0,5%. Masing-masing formula selanjutnya dievaluasi sifat fisik dan kimianya. Hasil evaluasi fisik menunjukkan bahwa secara organoleptis ketiga formula F1, F2 dan F3 memenuhi syarat sediaan gel, serta stabil ketika dilakukan pengujian sentrifugasi dan cycling test. Formuala F2 merupakan sediaan terbaik dalam pembuatan sediaan gel EPMS. Evaluasi stabilitas kimia menunjukkan bahwa kadar EPMS dalam sediaan gel hari ke- 0, 7, 14, dan 21 berada dalam rentang 91–100%. Sediaan gel mengalami penurunan kadar EPMS masing-masingnya sebesar 9% (F1), 5% (F2) dan 6%, (F3).

Ethyl p-methoxycinnamate (1) is the main secondary metabolite found in Kaempferia galanga Linn and has various interesting pharmacological activities, including anti-inflammatory, sedative, vasorelaxant, and antiangiogenic activities. This study aimed to optimize the conditions for the conversion of 1 to 4-methoxychalcone (2) using a conventional synthetic reaction. The conversion was initiated by the hydrolysis of 1 to p-methoxycinnamic acid (3) and 3 to 4-methoxybenzaldehyde (4), and continued with the Claisen-Schmidt reaction of 4 with acetophenone (5). The temperature (room temperature and 45 °C) and ratio of 4 to 5 (1:1 and 1:2) were varied to determine the optimal conditions for the reaction. The results suggested that the reaction of 4 with 5 gave the best yield (42.1 %) when conducted at room temperature in a ratio of 4 to 5 (1:1). The structure of the reaction product was elucidated by spectroscopic analysis and compared with previously published data
