摘  要：
为筛选能应用于柑橘保鲜的药用植物提取物,测定了博落回和虎杖提取物对柑橘绿霉菌的抑菌活性以及对柑橘保鲜的效果。结果表明:博落回和虎杖提取物均能抑制绿霉菌的生长,二者的有效中质量浓度分别为184.32、538.48 mg/L,博落回的抑菌效果比虎杖好;与清水对照相比,2种提取物处理柑橘的腐烂率均显著降低;与常规化学保鲜剂相比,2种提取物冰糖橙的腐烂率差异均无统计学意义,但椪柑的腐烂率均显著升高;2种提取物处理冰糖橙的失水率与常规化学保鲜剂处理的差异均无统计学意义,但显著高于清水处理,2种提取物对冰糖橙的防腐、保鲜能达到常规化学保鲜剂的效果。

摘  要：
For selection of medicinal plant extracts to be applied into citrus postharvest preservation,the inhibition effect of Macleaya cordata and Polygonum cuspidatum on Penicillium digitatum and its preservation effect during citrus storage were studied.The results were as follows: Both M.cordata and P.cuspidatum could inhibit growth of P.digitatum,ED50 of which were 184.32 and 538.48 mg/L respectively,especially the inhibition effect of M.cordata was better.With comparison of water treatment,the two kinds of medicinal plant extracts could both effectively prevent Bingtangcheng from decay.With comparison of conventional chemical preservative,the decay rates of Bingtangcheng respectively treated by the two kinds of medicinal plant extracts had no statistical significance,but Ponkan significantly increased.The water losing rates of Bingtangcheng respectively treated by the two kinds of medicinal plant extracts were no statistical significance compared with conventional chemical preservative,but the water losing rates of these three treatments were significantly lower than water treatment.The effects of the two kinds of medicinal plant extracts on decay and fresh-keeping of Bingtangcheng were similar to conventional chemical preservative.
