Identification and Quantification of Fatty Acids in T. viridissima, C. biguttulus, and C. brunneus by GC-MS

Table 1

The complete fatty acid profiles of both T. viridissima and Chorthippus sp., in order of elution. The average concentrations for T. viridissima are the result of three sample preparations, each containing three parallels. The average concentrations for Chorthippus sp. are the result of two sample preparations, each containing three parallels. All values are presented as µg/g of sample dry weight.
