Abstract

One of the extensively prosperous potential aromatic plants is the clove (Syzgium aromaticum). This is owing to all parts of this plant (bud, stem, and leaves) contain a decent amount of essential oils. The current study focuses on the use of microwave-assisted hydrodistillation (MHD) in extracting clove stem essential oils. This study aims to obtain the best possible combination of operating parameters for a high yield of clove stem oil using response surface methodology. The current study adopted a face-centered central composite design to optimize the MHD operational parameters, including the feed-to-solvent ratio, microwave power, and extraction time. The observed data from the experiments were fitted to a reduced quadratic polynomial equation. The three operational parameters were shown to significantly affect the extraction yield of the clove stem oil (p  < 0.05), yet the statistical significance for the interaction between each parameter was considerably weak. Furthermore, the adjusted R2 value measured comparably to the corresponding R2 value with the difference below 0.2, implying a high correlation between experimental and model-predicted data. Thus, this result demonstrates the suitability of the model used in the experiment.

Abstract

Essential oils are compounds extracted from plants and obtained by distillation. Indonesia has many kinds of plant commodities for essential oil production. Among the essential oils that have not been developed in Indonesia is citronella oil which can be extracted from the lemongrass plant this research, we develop Microwave Hydro-Distillation (MHD) method has several advantages over conventional distillation methods: shorter time, higher oil quality and yield. This research proposes to extract citronella oil from lemongrass leaves using the MHD method using aquadest and NaCl solution addition. Operating variables are extraction time (20–180 min), material size (0.5, 1.0, and 1.5 cm), feed-to-solvent ratio (0.1; 0.15; and 0.2 g/mL), and microwave power (300, 450, and 600 watts). The essential oil results are analyzed by GC-MS analysis, specific gravity, refractive index, and solubility. The results showed that it increased with extraction time followed by almost constant conditions, tended to decrease with increasing feed-to-solvent ratio, and increased yield with increasing microwave power. The results from the GC-MS analysis, the active substance content of geraniol was 46.61% and citronellal 5.62%. Additional salt in this method is a green and clean essential oil extraction.
