Schum) dan pabrikasi nanopartikelnya. Tujuan dari penelitian ini adalah untuk memperoleh isolat steroid dari rimpang lengkuas merah ( Alpinia purpurata K. Schum ) dan memperoleh nanopartikel steroid dari hasil isolasi. Senyawa steroid diisolasi dari fraksi n-heksana dengan maserasi, ekstraksi, dan kromatografi kolom. Nanopartikel steroid difabrikasi dengan ultrasonikasi. Struktur molekul steroid diidentifikasi dengan gas chromatography-mass spectrometer (GC-MS). Ukuran nanopartikel steroid dikarakterisasi dengan metoda dynamic light scattering (DLS) menggunakan alat particle size analyzer (PSA). Hasil menunjukkan bahwa isolat steroid mengandung senyawa golongan progesteron. Ukuran rata-rata nanopartikel steroid secara statistik adalah 95,0 ± 12,2 nm untuk nanopartikel steroid (StrNPs) kelompok I dan 670,2 ± 141,1 nm untuk StrNPs kelompok II.}, issn = {2597-9914}, pages = {48--52} doi = {10.14710/jksa.20.1.48-52}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/15341} }
