• Nowadays, plants containing biological activities are increasingly interested for their antioxidant and antibacterial properties. In particular, Pepper longum Linn. was known as one of the popular types of pepper family in Vietnam with many different uses in food and medicine. In this study, Pepper longum fruits were studied for extraction to essential oil by hydrodistillation through two survey methods such as single factor investigation method and optimization by response surface methodology (RSM). The analysis results by design expert software program version 11 shown that at the condition that the ratio of water to raw material 6:1 (mL/g), during 225 min extraction at 130 ºC, the essential oil yield was obtained 0.8%. The model predicts this result for F-value, P-values and Lack of Fit are mathematically significant and values for reliability R2 = 0.9963, C.V. % =1.99. Essential oil obtained was evaluated by gas chromatography-mass spectrometry (GC-MS) technique, which accounted that β-caryophyllene contains the highest amount among the other 43 components present.
