摘要
ＴＧ和ＰＬ是青蟹卵巢的主要脂类，以ＴＧ含量最高，肝胰腺脂类主要有ＴＧ、ＦＦＡ和ＰＬ．ＰＬ在肌肉的脂类中占绝对优势。随性腺发育，卵巢的ＴＧ、ＰＬ均增，而肝胰腺者则下降，肌肉的ＰＬ也显著减少，青蟹含有较高的１６：０、１６：１ω７、１８：１ω９、２０：５ω３和２２：６ω３酸，占总脂肪酸的５７．５９％～７５．９３％。随着性腺发育，卵巢１６：１ω７＋１８：１ω９和２０：５ω３＋２２：６ω３均上升，肝胰腺的１６：１ω７＋１８：１ω９在Ⅱ期显著上升，而Ⅲ期急剧下降，其２０：５ω３＋２２：６ω３变化趋势与之相似，但变幅较小。
The lipid classes from various organs &.tissues of Scylla serrata during the ovariandevelopment, analysed by thin-layer chromatosraphy, were as follows: Ovaries accumulated TG &PL as the major lipids, which contained 56. 3%～62.5% TG & 11.7%～16. 8% PL. Lipid classesof hepatopancreas mainly consisted of TG,FFA & PL,i. e. 32. 0 %～ 51 . 6% , 10. 7 %～ 29. 2 % , &1 3. 4 %～24. 5% respectively.PL,with a content of 32. 1%～60. 8 % , was a dominant constituentof lipids in muscle. With increasing maturity of the ovary , both TG & PL of ovaries increased,whilethose of hepatopocreas decreased. The PL of muscle decreased markedly during the ovarian develop-ment. Fatty acid compositions, analysed by gas-liquid chromatography,showed that the 16:0,16 :1ω7,18:1ωg , 22 : 5ω3 . & 22:6ω3 acids,altogether 57. 59 %～75. 93 % of the total FA contents,were dominat in S.serrata.With the ovarian developing,both contents of 16:1ω7 plus 18 : 1ωg& 20:5ω3 plus 22:6ω3 increased in ovaries,but those fluctuated in hepatopancreas,by increasingin 16:1ω7 plus 18 : 1ωg at stage Ⅱ&.decreasing at stage Ⅲ.
