✦ Synopsis

Abstract

Grass forage samples with different fiber content and composition, and their fibrous fractions, have been analyzed by pyrolysis – gas chromatography with ion trap detection. The identities of the pyrolysis fragments indicated their origin to be carbohydrates, lignin, and nitrogen compounds. Comparison of the resulting quantitative data by factorial variance revealed pyrogram peaks attributable to neutral detergent fiber, cellular contents, and lignin. Quantitative pyrolysis data from these components showed the same trends as those recorded by the method of Goering and Van Soest [1].

## Abstract Wheat straw lignins obtained by HF, H~2~SO~4~, HCL, NaOH, and dioxane/water extraction methods and native wheat straw were subjected to pyrolysis‐gas chromatography (Py‐GC). Pyrolytic fragments were tentatively identified by mass spectrometry using an on‐line Py‐GC‐Lon Trap Detector (Py
