Isolasi dan Identifikasi, Ethyl P-Methoxycinnamate, soxhlet, ekstrak metanolAbstract
Indonesia kaya akan keanekargaman tanaman obat. Salah satunya adalah rimpang kencur atau Kaempferia galanga L. Tanaman ini memiliki potensi besar sebagai sumber penting senyawa bioaktif yang dapat mendukung pengembangan obat-obatan alami serta mendorong penelitian lebih lanjut dalam bidang farmakologi dan pengobatan. Kaempferia galanga sendiri telah diteliti mengandung beragam senyawa yang dapat dimanfaatkan untuk berbagai aktivitas farmakologi salah satunya adalah antikanker. Salah satu komponen senyawa yang dimiliki oleh Kaempferia galanga yang dapat digunakan sebagai antikanker adalah etil p-methoxycinnamate (EPMC). Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi senyawa EPMC untuk memperoleh hasil isolasi yang maksimal dengan kadar EPMC yang tinggi. Metode isolasi EPMC dari tanaman kencur menggunakan soxhlet sebagai alat ekstraksi. Identifikasi dan penentuan kadar senyawa diperoleh menggunakan evaluasi KLT, GC-MS, NMR, HPLC dan Spektrofotometri UV-Vis. Hasil identifikasi menunjukkan isolat dari Kaempheria galanga merupakan senyawa ethyl p-methoxycinnamate dengan berat molekul 206 dan persentase kadar EPMC menunjukkan kadar yang tinggi baik menggunakan HPLC maupun spektrofotometer UV-Vis, dimana kadar EPMC dalam isolat didapatkan sebesar 90,40 ± 3,62 %, dan 91,29 ± 3,66 %. Sedangkan untuk kadar pada ekstrak metanol Kaempheria galanga adalah 49,57 ± 0,63 % dan 40,61± 0,25% berdasarkan hasil HPLC dan spektrofotometer UV-Vis. Berdasarkan hasil tersebut dapat disimpulkan bahwa metode isolasi EPMC dari tanaman kencur (Kaempferia galanga) menggunakan soxhlet sebagai alat ekstraksi memberikan rendemen ekstrak dan rendemen isolat yang tinggi.References
