Abstract

Reseptor merupakan sebuah makromolekul protein seluler bersifat spesifik yang berikatan langsung dengan ligan. Terapi molekuler reseptor digunakan sebagai target aksi obat dengan hasil efikasi tepat. Reseptor dopamine memiliki peran penting dalam kinerja kontrol pergerakan sebagai fungsi kognitif dan fungsi peredaran. Reseptor dopamine adalah suatu target aksi obat dalam terapi penyakit terapi seperti parkinson dan skizofrenia. Dopamine merupakan senyawa neurotransmitter endokrin pada kelas katekolamin dan memiliki peran sangat penting dalam mengontrol motorik, kognisi, kepuasan, dan gairah. Beberapa subtipe terdapat pada reseptor dopamine yaitu pertama D1&D5 sebagai pembentukkan cAMP dengan aktivasi merangsang protein G dan kedua D2, D3 & D sebagai menghambat pembentukkan cAMP mengaktifkan G-arrestin. Pada target aksi obat glutamat dapat mengurangi aktivitas glutamat yang berhubungan dengan perkembangan gejala skizofrenia. Skizofrenia merupakan seseorang yang mengalami gangguan mental kepribadian dan emosi, penyakit ini menyerang otak. Adapun peran dopamine dalam sistem saraf pusat adalah menunjukkan neuromodulator dalam psikosis penggunaan psikostimulan yang mengakibatkan pelepasan dopamin diselesaikan dengan menggunakan penghambatan dopamine. Dalam mengetahui target aksi obat terhadap reseptor dopamine dengan mengumpulkan beberapa jurnal internasional dari google scholar yang terpublikasikan.

Abstract

Curcumin, as the main active compound in Zingiberaceae plants, turmeric and temulawak, with various health benefits. That active compound generally exists in low concentrations, thus an effective and efficient method is needed to extract these compounds, such as Enzyme Assisted Extraction (EAE), one of which involves cellulase enzyme. This study aims to use the Enzyme Assisted-Extraction (EAE) method with cellulase enzyme in the extraction of curcumin from turmeric and temulawak plants, and to evaluate the extraction yield and efficiency of extract, comparing the curcumin content in turmeric and temulawak extracts between EAE and conventional maceration extraction method. The research was conducted using a Randomized Block Design (RBD) experiment with variations in temperature (45°, 50°, 55℃), time (1 hour, 2 hours, 3 hours), and enzyme concentration of 6%. The research stages included determining the water and ash content in the raw materials, water content in the extracts, extraction using maceration and EAE methods, determination of extract yield, extract purification, phenol screening, analysis of curcumin content using UV-Vis Spectrophotometry, and statistical analysis using the Mann-Whitney test. The results showed that the use of cellulase enzyme in the extraction process of turmeric and temulawak successfully increased the extract yield and curcumin content. The highest yield was obtained in turmeric at 34.24%± 0.038, and the highest curcumin content was achieved at a temperature of 45˚C for 2 hours, reaching 56.86% ± 0.090. Meanwhile, in temulawak, the highest yield was 53.11%± 0.385, and the highest curcumin content was obtained at a temperature of 50˚C for 2 hours, reaching 54.10% ± 0.100. There was an increase in curcumin content in turmeric and temulawak EAE extract compared to the conventional maceration extraction method. Statistical analysis using the Mann-Whitney test (p < 0.05,) indicating a significant difference between the EAE and conventional maceration extraction method.
