Objective To study the chemical constituents of Periploca Radix. Methods The chemical constituents of Periploca forrestii were separated using various chromatographic techniques. Their structures were elucidated by spectral analysis. Results Nineteen compounds were isolated from the 70% ethanol extract of P. forrestii, and identified as 3-O-caffeoylquinic acid methyl ester (1), 4-O-caffeoylquinic acid methyl ester (2), 5-O-caffeoylquinic acid methyl ester (3), 3-O-caffeoylquinic acid (4), 4-O-caffeoylquinic acid (5), 5-O-caffeoylquinic acid (6), 1,3-di-O-caffeoylquinic acid (7), 3,4-di-O-caffeoylquinic acid (8), 3,5-di-O- caffeoylquinic acid (9), 4,5-di-O-caffeoylquinic acid (10), protocatechuic aldehyde (11), p-hydroxybenzoic acid (12), o-hydroxybenzoic acid (13), syringic acid (14), vanillic acid (15), periforgenin A (16), Δ5-pregnene-3β,17α,20α-triol (17), periforgenin C (18), and periplogenin (19). Conclusion Compounds 1—12 are isolated from the plants of genus Periploca Linn. for the first time, and compound 13 is isolated from P. forrestii for the first time.
