Plant biomass is a major carbon-neutral renewable resource that could be used for the production of biofuels. Plant biomass consists mainly of cell walls, a structurally complex composite material termed lignocellulosics. Here we describe a protocol for a comprehensive analysis of the content and composition of the polyphenolic lignin.

This video demonstrates an assay to screen enzymes effective in degrading complex polysaccharides in plant biomass using insoluble chromogenic biomass or ICB. The enzymes hydrolyze ICB to release soluble dye-linked oligosaccharides, and the enzyme activity is assessed by colorimetric analysis of the reaction product.

Here, we present a modified TGA method for estimation of lignin content in herbaceous plant biomass. This method estimates the lignin content by forming specific thioether bonds with lignin and presents an advantage over the Klason method, as it requires a relatively small sample for lignin content estimation.
FAQs
Moisture and ash measurements provide foundational information for comparing plant-derived samples. Moisture helps account for differences in water content, while ash contributes to assessment of the sample’s inorganic fraction. Considering both measurements before evaluating carbohydrates, lignin, proteins, or other constituents improves interpretation of biomass quality and supports more consistent comparisons among feedstocks.
These constituents contribute different characteristics to plant tissues and biomass behavior. Structural carbohydrates such as cellulose and hemicellulose, along with lignin, help describe the composition and organization of plant material, while protein measurements add information about tissue composition. Separating them allows researchers to relate chemical makeup to digestibility, origin, quality, and processing behavior.
The techniques examine different aspects of the same biomass. Spectroscopy supports chemical assessment, microscopy reveals structural features, and elemental analysis contributes information about elemental composition. Used alongside gravimetric assays, these approaches provide a broader view than any single measurement and help connect the physical, chemical, and structural properties of plant material.
A useful workflow combines baseline measurements of moisture and ash with compositional analysis of structural carbohydrates, cellulose, hemicellulose, lignin, proteins, and other constituents. Researchers can then add spectroscopy, microscopy, or elemental analysis to examine chemical signals, structure, or elemental composition. This combined strategy links sample composition with quality and potential processing behavior.
It is useful when researchers need to compare plant materials from different origins, tissues, or growth conditions. Measurements can show how composition and structure vary, then relate those differences to biomass quality, digestibility, or suitability for conversion. Such comparisons support feedstock selection for fuels and bioproducts and help evaluate material for agricultural or ecological applications.
In biology, compositional and structural measurements help connect plant growth with the properties of resulting tissues. Analyses of carbohydrates, lignin, proteins, moisture, ash, and physical structure can reveal differences among plant materials without relying on a single indicator. The resulting profiles support studies of tissue composition, biomass quality, digestibility, and ecological relevance.
