采用亚临界水萃取法提取芒果中的有效成分芒果苷。亚临界水萃取温度为323~423K，压力为0.7~4.0 Mpa，提取时间为1~7h，用高效液相色谱法测定芒果苷的萃取率。温度对萃取率影响较大，压力对萃取率影响较小。随着萃取温度的升高，芒果苷的萃取率增加，这可能是由于较高温度下亚临界水的极性降低所致。在373K、4.0 Mpa、5h的最佳提取条件下，芒果苷的萃取率为21.7 mg/g，接近甲醇的萃取率(25.0 mg/g)，高于水和乙醇的沸点萃取率(18.6 mg/g和13.2 mg/g)。(C)2010年，由Elsevier B.V.代表韩国工业和工程化学学会出版。
A pharmacological active component, mangiferin, was extracted from Mahkota Dewa using subcritical water extraction. The subcritical water extractions were carried out at temperatures ranging 323-423 K, pressures ranging 0.7-4.0 MPa, and extraction times ranging 1-7 h. Extraction yield of mangiferin was measured using high-performance liquid chromatography (HPLC). The extraction yield was strongly dependent on the temperature while weakly dependent on the extraction pressure. As the extraction temperature increased, the extraction mangiferin yield increased, possibly resulting from the decrease in polarity of subcritical water at higher temperature. At an optimal extraction condition of 373 K, 4.0 MPa and extraction time of 5 h, the extraction yield of mangiferin was 21.7 mg/g. This value was close to the extraction yield with methanol (25.0 mg/g) and higher than those with water (18.6 mg/g) or ethanol (13.2 mg/g) at their boiling points.
