STUDIES ON CHEMICAL CONSTITUENTS OF THE ROOTS OF LANTANA CAMARA

Six oligosaccharides (Ⅰ～Ⅵ)and six iridoid glucosides (Ⅶ～Ⅻ) iso-lated from the ethanolic extract of Lantana camara roots were identified as stachyose (Ⅰ),verbascose (Ⅱ), ajugose (Ⅲ), verbascotetracose (Ⅳ), α-D-galac-1-6-α-D-galae-1-6-D-gluc (Ⅴ), α-D-galae-1-6-α-D-galac-1-6-D-glue (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 werenew compounds named lantanose A and lantanose B, respectively. The others were iso-lated from this plant for the first time.
