Penelitian ini untuk mengetahui pengaruh minyak atsiri daun cabe jawa terhadap bakteri uji sensitif serta difokuskan untuk melihat kerusakan membran sel bakteri melalui analisis protein, asam nukleat dan ion-ion logam kalsium dan kalium. Distilasi&#13;
uap minyak atsiri dari daun segar cabe jawa (Piper retrofractum Vahl.) menghasilkan 0.03% cairan kental kekuningan. Analisis dengan GC-MS mengidentifikasi 4 senyawa sebagai komponen utama, yaitu germakren D (24.20%), tetrametilsiklo[5.3.1.0(4.11)]-undek-8-ena (17.73%), ar-turmeron (11.55%) dan benzil benzoat (6.28%). Minyak atsiri cabe jawa terbukti aktif melawan beberapa bakteri patogen antara lain Staphylococcus aureus, Bacillus subtilis and Micrococcus luteus dengan diameter daya hambat berturut-turut 8.0; 9.7; 8.5 mm. Pengamatan lebih lanjut memperlihatkan nilai MIC dari minyak atsiri cabe jawa  terhadap B. subtilis adalah 2% (v/v), dan juga merubah morfologi sel dari bakteri yang diobservasi menggunakan SEM.</mods:abstract><mods:classification authority="lcc">QV Pharmacology</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8601">2013-06</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Sekretariat Badan Penelitian dan Pengembangan Kesehatan</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_5341"><mets:rightsMD ID="rights_eprint_5341_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
