| 摘 要： | 为开发新型安全的植物源柑橘保鲜剂，对5种中草药水提液进行抑菌试验，筛选出对柑橘青霉菌有较好抑制作用的中草药，并探讨鱼腥草丁香普鲁兰多糖复配保鲜剂对柑橘采后青霉菌抑制效果。丁香和鱼腥草水提液对柑橘青霉菌有较好抑制作用，抑菌率分别为73.45%和49.85%，对柑橘青霉菌的MIC分别为0.60 mg/mL和1.20 mg/mL，丁香和鱼腥草混合水提液抑制毒力较单一水提液的高，EC50为0.36 mg/mL。复配保鲜剂可有效抑制柑橘的发病率，在柑橘贮藏第9 d，比对照组CK发病率降低16.67%（p<0.05），但对失重率抑制效果不显著（p>0.05）。复配保鲜剂组有效延缓了果实可溶性固形物含量和可滴定酸度含量的增加，维持了较稳定的抗坏血酸含量，抑制了柑橘的呼吸强度。总之，丁香和鱼腥草水提液能有效抑制柑橘青霉菌菌丝体生长和孢子萌发，鱼腥草丁香普鲁兰多糖复配保鲜剂能提高柑橘对柑橘青霉病的抗性，该研究为开发新型安全的植物源柑橘保鲜剂提供理论支持。

| Abstract: | In order to develop a new plant-resource Citrus reticulata preservative, the inhibitory effects of water extracts from five plants were evaluated by antibacterial test, and the inhibition effects of Houttuynia cordata and Syzygium aromaticum and pullulan polysaccharide composite on Penicillium italicum after harvest were studied. The results showed that the Syzygium aromaticum and Houttuynia cordata water extracts had better inhibitory effect on Penicillium italicum, the inhibition ratios were 73.45% and 49.85% respectively, and the MIC were 0.60 mg/mL and 1.20 mg/mL respectively. The mixed Syzygium aromaticum and Houttuynia cordata water extracts had higher inhibitory toxicity than that of single water extracts, and the EC50 was 0.36 mg/mL. The decay rate of the compound preservative was 16.67% lower than that of CK group (p<0.05), but the inhibition effect on weight loss rate was not significant (p>0.05) after 9 days storage. The compound preservative could effectively delayed the increase of soluble solid content and titratable acidity content, maintained stable ascorbic acid content and inhibited the respiration intensity. The experimental results indicated that Syzygium aromaticum and Houttuynia cordata water extracts could inhibit spore germination and mycelial growth in Penicillium italicum; the compound preservative of Houttuynia cordata and Syzygium aromaticum and pullulan polysaccharide could improve the resistance of Penicillium italicum of Citrus reticulata. This study provides theoretical support for the development of new safe preservative of Citrus reticulate. |
