Structure Determination of a Natural Juvenile Hormone Isolated from a Heteropteran Insect
Figure 5
Chiral GC-MS(CI) analysis of synthetic standards of JHSB3 (1) and isomer 2 and natural product by the CA of Plautia stali using an Rt-βDEXcst column. Vertical axis indicates signal intensity for m/z 300, [M+NH4]+. Black, blue, and red lines indicate analysis of JHSB3 (1) and isomer 2 (10 ng each), CA product, and cochromatography of these two samples, respectively [15].
