Anting-anting plant (Acalypha indica L.) is a plant that the community has used as raw material for herbal medicine. Anting-anting plants contain chemical compounds, so it is difficult to ensure these plants' safety and quality control. The research objective was to validate the method by knowing the stability, specificity, precision, and rigidity of the chromatographic profile of alkaloid compounds in the TLC analysis of the anting-anting extract. Extraction was carried out using ethyl acetate solvent for 20 minutes with a frequency of 42 kHz. The eluent used is cyclohexane: toluene: diethylamine (75:15:10) with Dragendorff reagent. The method of validation was acceptable according to the criteria except for the stability test of the analyte during chromatography. The instability of the analyte is indicated that not all spots form a straight diagonal line. The specificity of the method was carried out by comparing the fingerprint patterns of the leaves of the anting-anting with ekor kucing (Acalypha hibsida Farm.) and teh-tehan plants (Acalypha siamensis). The fingerprint profile showed a yellow stain (Rf = 0.39) on the leaves of the anting-anting, which did not appear in the fingerprint profiles of the two comparison samples. Keywords: anting-anting, fingerprint analysis, thin layer chromatography, method validation Anting-anting (Acalypha indica L.) merupakan tanaman yang telah dimanfaatkan masyarakat sebagai bahan baku obat herbal. Anting-anting mengandung banyak senyawa kimia sehingga sulit menjamin keamanan dan pengendalian mutu dari tanaman tersebut. Penelitian ini dilakukan untuk validasi metode dengan mengetahui kestabilan, spesifitas, presisi, dan ketegaran profil kromatografi senyawa alkaloid pada analisis KLT ekstrak anting-anting. Ekstraksi dilakukan menggunakan pelarut etil asetat selama 20 menit dengan frekuensi 42 kHz. Eluen yang digunakan adalah sikloheksana : toluena : dietilamin (75:15:10) dengan reagen Dragendorff. Validasi metode dapat diterima sesuai kriteria kecuali uji stabilitas analit selama kromatografi. Ketidakstabilan analit ditunjukkan dengan seluruh noda yang dihasilkan tidak membentuk garis diagonal yang lurus. Spesifitas pada metode dilakukan dengan membandingkan pola sidik jari daun anting-anting dengan daun ekor kucing (Acalypha hibsida Farm) dan daun teh-tehan (Acalypha siamensis). Profil sidik jari menunjukkan bahwa terdapat noda berwarna kuning kehijauan (Rf = 0,39) pada daun anting-anting yang tidak muncul pada profil sidik jari kedua sampel pembanding tersebut. Kata kunci: anting-anting, analisis sidik jari, kromatografi lapis tipis, validasi metode
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
