The present observation records the lipid classes and their fatty acid composition of the neutral lipid and phospholipid of the trematode Paramphistomum cervi and liver of its host Capra hircus, the common Indian goat. Thin Layer Chromatography and Gas Liquid Chromatography were used to identify different neutral lipid and phospholipid components. The results show that among the neutral lipid fractions, the amount of combined hydrocarbon, wax ester and steryl ester is more or less equal in parasite and its host, but the percent of triacylglycerol is more in host liver than the parasite and the percent of total sterol is more in parasite than that of its host liver. Among the phospholipid fractions, phosphatidylinositol and phosphatidylethanolamine in the trematode parasite P. cervi and phosphatidylcholine and cardiolipin in the host's liver are the major components. The predominant fatty acids in the neutral lipid and phospholipid fractions of both the host liver and the trematode P. cervi include C16:0, C18:0, C18:1, and C18:2. The results reveal that the parasite P. cervi take up almost all the lipid and fatty acids from their host, which is required for their life cycle.
本观察记录了鹿同盘吸虫中性脂质和磷脂的脂质类别及其脂肪酸组成，以及其宿主印度普通山羊（Capra hircus）肝脏的相关情况。采用薄层色谱法和气液色谱法鉴定不同的中性脂质和磷脂成分。结果表明，在中性脂质组分中，寄生虫及其宿主中结合烃、蜡酯和甾醇酯的含量大致相等，但宿主肝脏中三酰甘油的百分比高于寄生虫，而寄生虫中总甾醇的百分比高于其宿主肝脏。在磷脂组分中，吸虫鹿同盘吸虫中的磷脂酰肌醇和磷脂酰乙醇胺以及宿主肝脏中的磷脂酰胆碱和心磷脂是主要成分。宿主肝脏和吸虫鹿同盘吸虫的中性脂质和磷脂组分中的主要脂肪酸包括C16:0、C18:0、C18:1和C18:2。结果显示，吸虫鹿同盘吸虫从其宿主摄取了几乎所有其生命周期所需的脂质和脂肪酸。
