Spl ） ，它们的粗提物对冠瘤海鞘幼体的附着和变态有抑制作用，这两种粗提物都是脂溶性的。

4.During experiment , acetylcholine shows significant inhibitory effects on the settlement and metamorphosis of ascidian larvae , but its concentration cannot lower 1 x 10 - 7mol / l . similarly acetylcholine , y - aminobutyric ( gaba ) and picrotoxin also can inhibit the settlement and metamorphosis of s . canopus larvae

实验中，乙酰胆碱对冠瘤海鞘的附着变态表现出抑制作用，但当浓度降低到10 ~ ( - 7 ) mol l时，此作用已不明显。

5.According to the frequently used methods of extraction and isolation of natural products from organic body , the freeze - dried ascidian tunica was exhaustively extracted with 100 % chloroform then the combined extracts were filtered and the solvent was separately concentrated under vacuum to yield a dark - brown gum
