【 摘 要 】

To optimize the extraction process of total flavonoids from bitter bamboo shoots and sinocalamus affinis shoots, and compare their contents, to provide technical reference for the value by two kinds of bamboo shoots. Based on the three factors of ethanol concentration, extraction time and extraction temperature, orthogonal test was designed to determine the content of total flavonoids in bamboo shoots and the optimum extraction conditions were selected. The results showed that the total flavonoids contents of bitter bamboo shoots reached to 10.655 mg/g when 60% ethanol concentration, 70°C extraction temperature and 1.5 h extraction time; the total flavonoids contents of sinocalamus affinis shoots reached to 32.24 mg/g when ethanol concentration, extraction temperature and extraction time were 60%, 80 C and 1.5 h. The total flavonoids content of the sinocalamus affinis shoots was significantly higher than that of the bitter bamboo shoots, and the medical value was higher than that of the bitter bamboo shoots.
