川芎等中草药提取物对柑橘病原菌的抑制作用

Application of Chuanxiong and Other Chinese Herbal Medicine Extracts in Restraining Cirtus Pathogens and Cirtus Fresh-keeping

为探究中草药提取物对柑橘病原菌的抑菌效果,以川芎、五加皮、独活等6种中草药作为原料从中提取抑菌液,测定其对3种柑橘病原菌(白霉、柑橘褐腐疫霉、指状青霉)的抑菌效果。结果表明,不同中草药提取液对不同柑橘病原菌的抑菌效果均不同,其中,川芎的抑菌作用最为明显,当其浓度低至1.0×10-3g/m L时,对3种病原菌仍有较好的抑制效果。进一步的涂膜保鲜试验证明,添加0.10%川芎提取液于壳聚糖膜中,对柑橘保鲜效果有明显增强作用。

In order to research the inhibition effect on citrus pathogen with Chinese herbal extracts, Rhizoma ligustici Chuanxiong, Cortex acanthocephala Radicis, Radix angelicae Biseratae and other 6 Chinese herbals were used as materials for antibacterial liquid extraction, and the antibacterial effect on 3 kinds of cirrus pathogens （white mold, brown rot phytophthora and finger penicillium） were identified. The results showed that the extracting liquid of Chinese herbal had different inhibiting effects on different cirtus pathogen, and the inhibiting effects of Rhizoma ligustici Chuanxiong were the most obvious. When the extracting liquid density of Rbizoma ligustici Chuanxiong was below 1.0× 10^-3 g/mL, it still had obvious inhibiting effects on 3 kinds of cirtus pathogens. The film preservation tests indicated that adding Rhizoma ligustiei Chuanxiong of a density of 0.10% into chitosan membrane would have obvious enhanced effects on fresh citrus.
