Concentrations (pg/g) of sterols in 5<sup>th</sup> instars desert locusts fed on wheat seedlings.
收藏资源简介:
Retention time (Rt), wheat seedlings (W), oral secretion (OS), foregut (FG), midgut (MG), hindgut (HG), frass (F), hemolymph (H) and fat body (FB). Concentrations of sterol bearing the same letter in various tissues and secretions (across the column) are not significantly different (P≤0.05, Tukey’s, HSD test). ○ Identified by comparison with authentic samples. ◊ Identification by library data and through derivatization. ✘ denotes not detected. Concentrations (pg/g) of sterols in 5th instars desert locusts fed on wheat seedlings.
保留时间(Retention time, Rt)、小麦幼苗(wheat seedlings, W)、口部分泌物(oral secretion, OS)、前肠(foregut, FG)、中肠(midgut, MG)、后肠(hindgut, HG)、虫粪(frass, F)、血淋巴(hemolymph, H)与脂肪体(fat body, FB)。 不同组织与分泌物同列中标注相同字母的甾醇浓度无显著差异(P≤0.05,Tukey’s HSD检验)。 ○ 通过与标准品比对完成鉴定。 ◊ 通过谱库数据结合衍生化法完成鉴定。 ✘ 表示未检出。 以小麦幼苗为食的5龄沙漠蝗体内甾醇的浓度(单位:pg/g)。
