Abstract

Tumbuhan Pala (Myristica fragrans Houtt) termasuk dalam famili Myristicaceae. Penelitian tentang ekstraksi daun Pala dan uji toksisitasnya dengan metode Brine Shrimp Lethality Test (BSLT) telah dilakukan. Ekstraksi 3 Kg (3000 g) daun Pala dengan metanol diperoleh ekstrak metanol 417,60 g (13,92%). Ekstrak metanol d i larutkan ke dalam et il asetat diperoleh ekstrak et il asetat 104,1 g (5,96%). Hasil part isi ekstrak etil asetat dengan n-heksana diperoleh esktrak n-heksana 67,24 (68,53%) dan totalflavonoid 32,76 g (31,47%). Hasil uji akt ivitas sitotoksik ekstrak etil asetat, total flavonid metanol, dan n-heksana dengan metode Brine Shrimp Lethality Test (BSLT) berturut-turut LC 50 15,34 pp m; 30,92 pp m; 89,72 pp m dan 118,00 pp m.

Abstract

This research about of poisonous plant in the Explorationof Poisonous Plants on Martelu Purba Nature Preserve doing analysis identification, secondary metabolit, and potential development of the aspect local knowledge with survey local knowledge. The second is aspect biodiversity with analysis of vegetation data collection. And the third is aspect phytochemical with detect the contain of secondary metabolit. The exploration of poisonous plant in Cagar Alam Martelu Purba  finded 16 kinds of toxic plants. The result of this research shows that five kinds of toxic plants which has a greater chance that cultivated as asource of biopesticide is Latong andosari (Alstonia scholaris L.R. Br), Birah (Alocasia arifolia Hallier. F), Langge (Homalonema propinqua Ridl),  Hau palu-palu ni ogung (Canarium album Raeusch), Andor hutdali   (Dioscorea sp.), Flacourtia rukam Zoll. & Mortizi, Lang-lang habungan (Coleus scutellariodes (I).
