Objective: To isolate the chemical constituents from the whole plant of Pyrola decorata and identify their structures. Method: The constituents were isolated by chromatography methods; the structures of these compounds were identified by pysico-chemical constants and spectral analysis. Result: Ten compounds were isolated and elucidated as: chimaphilin (1)
oleanolic acid (2)
ursolic acid (3)
toluhydroquinone (4)
vanillic acid (5)
pomolic acid (6)
maslinic acid (7)
colosic acid (8)
3-β-O-α-L-arabinopyranosyl siaresinolic acid-28-O-β-D-glucopyranosyl ester (9) and ziyuglycoside I (10). Conclusion: Compounds 1~10 were isolated from this plant for the first time and compounds 6~10 were isolated from Pyrola species for the first time.
