The fatty acid composition of the kernel of Chimonanthus praecox cv. Luteus (FKC) was analyzed by gas chromatography-mass spectrometry (GC-MS), its ability to kill Pomacea canaliculata was detected, and the degree of damage and physiological and biochemical effects of an FKC soaking treatment on the hepatopancreas tissue of P. canaliculata were evaluated. In total, 16 fatty acids were detected in FKC, among which 13 were qualitatively identified; octadecadienoic acid (56.76%) and palmitic acid (17.03%) had the highest contents. After 48 h of treatment with FKC, the hepatopancreas of P. canaliculata had a large area of necrosis. The contents of soluble sugar, soluble protein, and albumin (Alb) in the hepatopancreas of P. canaliculata decreased with increasing FKC concentration. The content of malondialdehyde (MDA) and the activities of cereal third transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (AKP), and acetylcholinesterase (AChE) increased with increasing FKC concentration. The results showed that FKC has an obvious negative effect on the hepatopancreas cell structure and physiological function of P. canaliculata, i.e., has strong molluscicidal activity.

蜡梅籽粒中脂肪酸的杀软体动物活性。Luteus 对抗金苹果蜗牛 Pomacea canaliculata

Chimonanthus praecox cv. 仁的脂肪酸组成。用气相色谱-质谱联用仪(GC-MS)分析黄芪(FKC)，检测其对小叶斑病菌(Pomacea canaliculata)的杀灭能力，以及FKC浸泡处理对小叶斑病菌肝胰腺组织的损伤程度和生理生化作用被评估。FKC共检出16种脂肪酸，其中定性鉴定13种；十八碳二烯酸（56.76%）和棕榈酸（17.03%）的含量最高。FKC治疗48小时后，小管藻肝胰腺出现大面积坏死。P. canaliculata 肝胰腺中可溶性糖、可溶性蛋白和白蛋白（Alb）的含量随着 FKC 浓度的增加而降低。丙二醛（MDA）含量和谷物第三转氨酶（ALT）、天冬氨酸转氨酶（AST）、碱性磷酸酶（AKP）和乙酰胆碱酯酶（AChE）的活性随着FKC浓度的增加而增加。结果表明，FKC对P. canaliculata的肝胰腺细胞结构和生理功能有明显的负面影响，即具有较强的杀软体动物活性。
