4. Conclusions 1. The method of gas chromatography was successfully optimised for a reliabie oeteňation of individual components in coiophony and Mexioan coPai' ificant 2. of arl the stu<iied pigments, verdigris exhibits the most stgn effect on the composition of fresh corophony and Mexican copal' 3. The degradative processes caused by aftif,rcial ageing of diterpenoids (pimaradiene tolttul"' and abietadiene acids) in colophony and triterpenoids (ct- and B-amyrin) in Mexican copal were detected' ___________ i I -. l i3 c:oriern oť u]tramícrotom. ,,.^'::..:. distonion can be solved by the use oť compare tt," int.u.i A more convenienl reÍlection ...nn,o,..o spectra ", ;;;": J:ffi: ";J-",,;,J.5.
