Study on extraction technology of Vaccinium Fragile Franch / 国际中医中药杂志

ABSTRACT

ObjectiveTo study the best extractive process for Vaccinium Fragile Franch. Methods Single factor and orthogonal experiments were designed to determine the extractive rate as the index of evaluation and to optimize the extraction technology. ResultsThe experiments showed that adding 9 times of 70％ methanol, refluxing for 2 times, each times 2 hours at the 65℃C was the best extractive process.ConclusionThe process was stable and reasonable, which formed the scientific and reasonable basis for developing the active parts from Vaccinium Fragile Franch.
