Abstract


Through the optimization of sample pretreatment and chromatographic conditions , the establishment of a high-performance liquid chromatography - coupled with diode array detector (HPLC-DAD) method for three diaryl heptanes anticancer constituents Walnut A Walnut the walnut B and horsetail tree prime and α - tetralone derivatives - Walnut ketone Determination . Using this method to study the impact of the four indicators Walnut compound content of the main producing areas of western China walnut harvest time , the results show that the difference between the measured ingredients more significant . Of the Act for the Walnut Peel comprehensive utilization and related research and development of new drugs to provide a basis for . Cynomorium total flavonoids and catechins content , extract yield and anti-free radical activity evaluation index, the orthogonal experiment L to 9 ( 3 4 < / sup> ) the material ratio , extraction time and extraction times on the extraction process , the preferred Cynomorium optimum extraction process for 14 times the amount (mL / g) , 60% ethanol , reflux 3.0 h, extracted once . The process of industrialization and development Cynomorium reference.
