 Abstract
Telah dilakukan penelitian pendahuluan uji toksi.sitas 21 ekstrak etanol dari 20 tanaman. yang diduga mempuny i. khasiat, menggunakan metode Meyer yang dimodifikasi. Sebagai hewan percobaan digunakan Artemia sauna Leach umur 7 han. Dosis pemeriksaan adalah 100 dan 1000 ug/ ml dengan pengamatan setiap jam pada 6.. jam pertama dan 24 j'axn setelah penambahan ekstrak. Hasil pengamatan menunjukkan peningkatan prosentase kematian dengan bertambahnya dosis dan lamanya waktu kontak. ......A preliminary toxicity study was performed on 21 e - thanolic extracts of 20 plants, which were known to be active, using a modified Meyer's method. This study involved exposing one week old Artemia sauna Leach to plant ex - tracts of consentrations of 100 and 1000 ug/ml for 24 hours. Observations were done by counting, the number of death shrimp each hour in the first 6 hours and after 24 hours. The percentage of death shrimp increased . with higher extract concentration and longer length of exposure.
