Essential Oil Yield

Pomelo leaves oil has many applications regarding hair nourishment and stimulation. Recently, new methods of extracting essential oil used have been increasingly developed to replace traditional methods. In this research, maximization of essential oils yield from Citrus grandis was studied by the combination of microwave assisted hydro-distillation (MAHD) and response surface methodology (RSM). We found that the maximum essential oil yield was 0.3197 % with 91.3 % desirability corresponding to factors such as material and water ratiosof 3.04:1, extraction time at 62.76 min and microwave power of 482.17 W. ANOVA analysis for quadratic model also gives favourable outcome including the high determination coefficient (R2 = 0.9443), significant F-value and p-value of coefficients. All these values indicate that this model is significant between experimental and predicted variables.

AbstractCitrus reticulata cv. Chachiensis, a traditional Chinese herb, has extensive medicinal and edible effects. 3′,4′,5,6,7,8-Hexamethoxyflavone (HM) and 5,6,7,8,4′-pentamethoxyflavone (PM) are main bioactive compounds in Chachiensis, which have been reported to possess various biological properties. In this study, supercritical CO2 extraction (SCE) and high-speed countercurrent chromatography (HSCCC) were utilized to prepare HM and PM from Chachiensis. The contents of target compounds were determined by a high-performance liquid chromatography method with diode-array detection (HPLC-DAD), which was validated using the following parameters: linearity, sensitivity, repeatability, stability, precision and accuracy. The SCE conditions were optimized using response surface methodology with central composite design. Obtained optimum conditions were temperature of 37.9 °C, pressure of 26.3 MPa, and modifier volume of 81.0 mL. Under above conditions, the recoveries of target compounds were 92.52 ± 0.83 and 96.36 ± 0.43%, respectively. The most appropriate solvent system for HSCCC was selected as n-hexane/ethyl acetate/methanol/water (1:0.8:1:1.2, v/v). The HSCCC fractions were detected by HPLC-DAD, liquid chromatography-mass spectrometry (LC-MS) and nuclear magnetic resonance spectroscopy (1H NMR and 13C NMR). The results indicated that this method was successfully applied to obtain HM and PM with high purities and high recoveries from Chachiensis.
