 Leaves: "The leaves of Javaneese pepper (Piper retrofractum Vahl.) has been proven efficacious as antimicrobial agent, however, there was no further information about action mechanism of antibacterial of Javaneese pepper leaves essential oil... Steam distillation of essential oil from fresh leaves of Javanese pepper (Piper retrofractum Vahl.) gave 0.03 % yellowish viscous liquid. Germacrene D (24.20 %), tetramethylcyclo[5.3.1.0(4.11)]-undec-8-ene (17.73 %), ar-turmeron (11.55 %) and benzyl benzoate (6.28 %) were identified as major constituents analyzed by GC-MS. Javaneese pepper [leaves] essential oil was active against pathogenic bacteria Staphylococcus aureus, Bacillus subtilis and Micrococcus luteus..." \\

 In a comparativ study of the fruits of five pepper species species available in the region of Mumbai (India),
-Piper nigrum, Piper longum, **Piper retrofractum**, Piper cubeba and Piper betle were evaluated for physicochemical properties including volatile oil content and piperine content. Volatile oil content was 1.6, 0.2, **0.8**, 4.4, 0.2% respectively. Pierine content was 1.7, 0.3, **0.95**, 0.15, 0.9%, respectively. \\
