Abstract

Penelitian ini bertujuan untuk melakukan karakterisasi simplisia dan ekstrak etanol daun jeruk sambal (Citrus x Macrocarpa Bunge) yang berasal dari Kabupaten Sekadau, Kalimantan Barat. Karakterisasi simplisia meliputi identitas, organoleptis, kadar sari larut air dan etanol, serta susut pengeringan. Sementara itu, karakterisasi ekstrak meliputi kadar air, kadar abu total, kadar abu tidak larut asam, serta bobot jenis. Proses pembuatan simplisia dilakukan melalui sortasi basah, pencucian, perajangan, pengeringan, dan sortasi kering. Ekstraksi dilakukan dengan metode maserasi menggunakan etanol 70%, dilanjutkan pemekatan dengan rotary vacuum evaporator. Hasil karakterisasi menunjukkan bahwa susut pengeringan simplisia sebesar 6,34%, kadar sari larut air 24,67%, dan kadar sari larut etanol 20,67%. Ekstrak memiliki kadar air 25,71%, kadar abu total 9,58%, kadar abu tidak larut asam 1,53%, dan bobot jenis 0,89 g/ml. Hasil ini menunjukkan bahwa simplisia dan ekstrak memenuhi kriteria parameter mutu yang ditetapkan dan berpotensi sebagai bahan baku sediaan obat tradisional. Penelitian ini memberikan data awal untuk standarisasi ekstrak daun jeruk sambal sebagai kandidat bahan obat herbal.

Abstract (English)

This study aims to characterize the simplicia and ethanol extract of sambal lime leaves (Citrus x macrocarpa Bunge) originating from Sekadau Regency, West Kalimantan. The characterization of the simplicia includes identity, organoleptic properties, water-soluble and ethanol-soluble extractive values, as well as drying shrinkage. Meanwhile, the extract characterization includes water content, total ash content, acid-insoluble ash content, and specific gravity. The simplicia preparation process involved wet sorting, washing, slicing, drying, and dry sorting. Extraction was carried out using maceration with 70% ethanol, followed by concentration using a rotary vacuum evaporator. The results of the characterization showed that the drying shrinkage of the simplicia was 6.34%, water-soluble extractive value was 24.67%, and ethanol-soluble extractive value was 20.67%. The extract had a water content of 25.71%, total ash content of 9.58%, acidinsoluble ash content of 1.53%, and specific gravity of 0.89 g/mL. These results indicate that the simplicia and extract meet the established quality parameter criteria and have potential as raw materials for traditional medicinal preparations. This research provides preliminary data for the standardization of sambal lime leaf extract as a potential herbal medicine candidate
