dc.description.abstractA antimicrobial of activity of avocado seed extracts (Persea americana Miill.) to several microbial pathogens in vitro had been conducted. This study aims to determine the antimicrobial potential of avocado seed extract towards several microbial pathogens in vitro. The results of antimicrobial activity of various solven extracts test showed that avocado (Persea americana Mill.) seed extract inhibit growth of Candida albicans, Escherichia coli, Staphylococcus aureus and Salmonella thypii. Inhibition zone of seed extract in varions solven, they are Metanol,Etil asetat and n-Heksan have similar value at concentration 5%, 10% 15% and 20%. The Brine Shrimp Lethality test showed avocado seed extract has a very high toxicity. Ethyl acetate extract was the most toxic. The result showed that the Metanol extract contains compounds secondary metabolites compounds alkaloid and phenolic. Ethyl acetat extract of secondary metabolit tontain alkaloids class and fenolik the ethyl acetate extract containing scondary metabolites and terpenoid class of n-hexana extract containing secondary metabolites terpenoids class and phenolic.compounds terpenoid and phenolic.en_US
dc.description.abstractPenelitian aktivitas antimikroba ekstrak biji alpukat (Persea americana Mill.) terhadap beberapa mikroba patogen secara in vitro telah dilaksanakan. Penelitian ini bertujuan untuk mengetahui potensi antimikroba ekstrak biji alpukat terhadap beberapa mikroba patogen secara in vitro. Hasil uji aktivitas antimikroba berbagai pelarut ekstrak biji alpukat menunjukkan hambatan pertumbuhan terhadap Candida albicans, Escherichia coli, Staphylococcus aureus dan Salmonella thypii. Zona hambat ekstrak biji alpukat berbagai pelarut yaitu Metanol, Etil asetat dan n-Heksana memiliki nilai yang hampir sama pada konsentrasi 5%, 10% 15% dan 20%. Uji Brine Shrimp Lethality Test menunjukkan ketiga ekstrak biji alpukat memiliki toksisitas yang sangat tinggi. Ekstrak etil asetat merupakan yang paling toksik. Hasil uji yang dilakukan didapatkan bahwa ekstrak metanol mengandung senyawa metabolit sekunder golongan alkaloid dan fenolik, ekstrak etil asetat mengandung senyawa metabolit sekunder golongan terpenoid dan ekstrak n-heksana mengandung senyawa metabolit sekunder golongan terpenoid dan fenolik.en_US
