Objective To study the chemical constituents of Vespae Nidus. Methods The compounds were isolated by various chromatographic techniques and the structures were elucidated on the basis of spectral analysis. Results Sixteen compounds were isolated from 95% ethanol extract of Vespae Nidus by silica gel, Sephadex LH-20, and RP-18 column chromatography. They were identified as anisaldehyde (1), 2, 4-dihydroxy-3, 6-dimethylbenzoate (2), 1, 4-dihydroxy-2-methoxy benzene (3), 2-(4-methoxyphenyl) acetic acid (4), glycerol (5), tyrosol (6), 3, 5-dihydroxy-1, 7-bis (4-hydroxyphenyl) heptane (7), vomifoliol (8), clemaphenol A (9), N-benzoyl-L-phenylalaninol (10), asperglaucide (11), (2R, 3S)-2-(3′, 4′-dihydroxyphenyl)-3-acetylamino-7-hydroxyethyl-1, 4- benzodioxane (12), ursolic acid (13), β-sitosterol (14), thymidine (15), and neoechinulin A (16). Conclusion Compounds 1―13 and 16 are isolated from Vespae Nidus for the first time.
