Abstract： In this paper, the biological indexes included the relative germinating rate, the index of allelopathic were selected to investigate the effects of different extract solutions of Hydrocotyle vulgaris on seed germination of three test plant species. The chemical constituents extracted by water from the plants and rhizospheric soils of Hydrocotyle vulgaris were analyzed by GC-MS and LC-MS, to explore the main chemical constituents of Hydrocotyle vulgaris which may affect the other plants. The results were as follows: (1) Chemistry components of Hydrocotyle vulgaris in different extracts solutions all inhibited the seed germinating rate of Raphanus sativus, Brassica chinensis, Cucumis sativus, and the inhibition effects were significant for Raphanus sativus. (2) 35 and 17 compounds were identified from waters extracts in plants and rhizospheric soils of Hydrocotyle vulgaris by GC-MS. The common organics included Dibutyl phthalate, 10,15-Octadecane diacid and 2,4-Di-tert-butylphenol in water extracts of plant. The common organics included Oleic acid amide, N-hexadecane and Ethyl palmitate in the water extract of rhizospheric soil. (3) 109 and 93 compounds were identified from water extracts of plant and rhizospheric soils by LC-MS. By ESI+, The relative content of L-phenylalanine and Luteolin were the main components in water extract of plant, and the relative content of L-phenylbutyric acid and Palmitamide were the main components in rhizospheric soil. By ESI-, the relative content of L-phenylpropyl dextro-quinic acid and Chlorogenic acid were the main components in water extract of plant, and the relative content of L-phenylpropanoid octadecanoic acid and Sucrose were the main components. (4) Butyric acid, Octadecanoic acid, Glycolic acid, Oleic amide, Palmitamide, Ethyl hexadecanoate, Benzoic acid maybe affect the growing and surving of companion organism directly, which belonged to fatty acids, amides, esters and aromatic acids. Oleic amide, Palmitamide, Ethy hexadecanoate, Benzoic acid may originate in plants or transformed from secretion of plants by soil organisms, and the input pathways of Butyric acid, Octadecanoic acid, Glycolic acid include plants, micro-organisms and soil animals.
