Liquid chromatography and color development tests were carried out on water extracts from sewage sludge and its composted products to obtain information on a measure of compost maturity.The results can be summarized as follows.1) A liquid chromatogram of a water extract from compost using a gel-type column remarkably differed from that of raw sludge; the fraction of low molecular organics was much larger than that of high molecular components in the water extract from raw sludge, and vice versa in the extract from compost.2) Liquid chromatograms of water extracts from various composts produced under different fermentation conditions showed a similar pattern.3) In water extracts from compost, organic material with a broad molecular weight distribution ranging from 1000 to 100000,and some with narrow molecular weight distributions at around 3000,6000 and 100000 were present. The amount of the component with a molecular weight of around 6000 was the largest of the components which showed a narrow distribution.4) By color development tests, amino compounds, organic acids and polysaccharides were detected in the extract from sludge, and polysaccharides were detected in that from compost.
