Abstract

Penelitian ini bertujuan untuk memperoleh senyawa sitronelol dari reduksi sitronelal menggunakan NaBH4 dan mensintesis sitronelil propionat melalui reaksi esterifikasi Fischer antara asam propionat dan sitronelol hasil reduksi.Penelitian ini dimulai dengan mereduksi sitronelal menjadi sitronelol menggunakan reduktor NaBH4 dan pelarut etanol pada suhu 76oC selama 1 jam. Kemudian, hasil reduksi sitronelal direaksikan dengan asam propionat melalui reaksi esterifikasi Fischer menggunakan katalis asam sulfat pekat pada suhu 48oC selama 2 jam. Senyawa hasil reduksi sitronelal dan hasil esterifikasi Fischer diidentifikasi menggunakan KLT, spektrometer IR, dan spektrometer GC-MS.Hasil penelitian ini menunjukkan bahwa reduksi sitronelal menghasilkan sitronelol berupa cairan jernih tak berwarna dengan kemurnian 94,38% (rendemen 83,45%). Hasil reaksi esterifikasi Fischer antara asam propionat dengan sitronelol menghasilkan sitronelil propionat berupa cairan jernih tak berwarna dengan kemurnian 62,11% (rendemen 29,09%).

Abstract

Medicinal raw materials from agricultural products or groups of wild plants cannot be guaranteed; their chemical content is always constant due to variations in seedlings, body location, climate, or raw material conditions (age and harvest method). The content of the chemical compounds responsible for the biological response must have a chemical specification, i.e., information about the composition of both type and content. Standardization was carried out on specific parameters, including organoleptics, yield, the content of drying losses, water-soluble extract content, ethanol-soluble extract content, and chromatogram patterns. Non-specific parameters of the extract included water content, total ash content of powder and extract. The method of determination is carried out in accordance with the procedures established by Farmakope Herbal Indonesia (FHI 2017). Profiling has been done using infrared spectroscopy. Specific parameters showed that the organoleptic was a semisolid form with a dark green color, a distintive smell of dadap serep leaf extract, bitter sweetness, a yield of 7,63%, a drying loss of 7,51%, a water-soluble extract content of 4,86%, a level of ethanol-solubility extract content of 33,47%, and chromatogram patterns that were typical. Non-specific parameters indicate that the water content is 1,11%, acid-insoluble ash powder content 5,050 ± 0,036%; extract 0,986% and total ash powder content is 8,671 ± 0,303%; extract 4,123%. The results of parameter simplicia as well as ethanol extracts of leaves of Dadap Serep obtainable from the Magelang in accordance with the specifications in FHI 2017 and the spectroscopic photometer profile showing the typical pattern of extract and simplisia leaves.
