Eight triterpenoids were isolated from the roots of Lantana camara. On the basis of their chemical properties and spectral data (UV, IR, MS, 1HNMR, 13CNMR), they were identified as lantanolic acid (I), 22 beta-O-angeloyl-lantanolic acid (II), oleanolic acid (III), 22 beta-O-angeloyl-oleanolic acid (IV), 22 beta-O-senecioyl-oleanolic acid (V), 22 beta-hydroxy-oleanolic acid (VI), 19 alpha-hydroxy-ursolic acid (VII) and 3 beta-isovaleroyl-19 alpha-hydroxy-ursolic acid (VIII). II was obtained for the first time from plant. VIII is a new compound named lantaiursolic acid.

Six oligosaccharides (I-VI) and six iridoid glucosides (VII-XII) isolated from the ethanolic extract of Lantana camara roots were identified as stachyose (I), verbascose (II), ajugose (III), verbascotetracose (IV), alpha-D-galac-(1-[-6)-alpha-D-galac(-1](3)-6-D-gluc(V ) , alpha-D-galac-(1-6)-alpha-D-galac(-1]-(4)6-D-)gluc(VI) , theveside (VII), 8-epiloganin (VIII), shanzhsid methyl ester (IX), theviridoside (X), lamiridoside (XI) and geniposide (XII), on the basis of spectral analysis (1H-NMR, 13C-NMR, FD-MS, GC-MS), physico-chemical constants and preparation of derivatives. V and VI were new compounds named lantanose A and lantanose B, respectively. The others were isolated from this plant for the first time.

An exclusive constituent has been isolated from the water soluble parts of root of Codonopsis pilosula for the first time. The constituent has been confirmed to be tangshenosid I.
