Determination of the effects of estivation and starvation on neutral lipids and phospholipids in Biomphalaria glabrata (NMRI strain) and Helisoma trivolvis (Colorado strain) snails by quantitative high performance thin layer chromatography-densitomet

摘要

High performance thin layer chromatography (HPTLC) was used to determine neutral lipids and phospholipids in Biomphalaria glabrata (NMRI strain) and Helisoma trivolvis (Colorado strain) snails during estivation and starvation. Control snails were maintained on a diet of Romaine lettuce leaves. HPTLC analyses showed a significant (ANOVA, P < 0.05) decrease in triacylglycerols in estivated and starved snails compared to the controls and a significant increase in steryl esters in estivated and starved snails compared to the controls.
