Abstract:

Phyllostachys heterocycla (Carr.) Mitford cv. Pubescens Mazel ex H.de leh. leaves were used as raw material to extract volatile oil using a modified oil extraction apparatus. Based on single factor experiments, the optimal extraction process was determined using central composite design combined with response surface methodology. Results showed that the optimal extraction process was based on heat reflux extraction of powdered raw material below 10 mesh in particle size with distilled water at a liquid/solid ratio of 35:1 (mL/g) for 4.5 h. The observed and predicted values of extraction yield of volatile oil from Phyllostachys heterocycla (Carr.) Mitford cv. Pubescens Mazel ex H.de leh. leaves were 0.32% and 0.35%, respectively. This method has some advantages over conventional method, like simplicity as well as high extraction yield and abundant chemical composition of volatile oil.

Key words: Phyllostachys heterocycla (Carr.) Mitford cv. Pubescens Mazel ex H.de leh leaves, volatile oil, extraction, response surface analysis
