Isolation and identification of the chemical constituents from stems and leaves of Arachis hypogaea L / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the chemical constituents from the stems and leaves of Arachis hypogaea L. METHODS: Various column chromatographic techniques were used to separate and purify the chemical constituents and their structures were elucidated by spectral analysis. RESULTS: Fifteen compounds were isolated and identified as 4,9-dihydroxy-3-methothxy-coumestan(I), 3-hydroxy-9-dimethothxycoumestan (II), 3-isopropyl-pyrrolopiperazine-2,5-dione(III), 3-isobutylpyrrol-opiperazine-2,5-dione(IV), uracil(V), thymine(VI), thymidine(VH), L-(-)-phenylalanine(VI), nicotinic acid(IX), 2-furancarboxylic acid(X), ferulic acid (XI), vanillic acid(XII), 2-hydroxybenzoic acid(XIII), amber acid(XIV), and methyl hydrogen succinate(XV). CONCLUSION: The compounds I-IX are isolated from Arachis hypogaea L. for the first time.
