“…The n-BuOH extract was concentrated in vacuo and 8 was purified by normal phase silica HPLC with a mobile phase of hexanes/EtOAc (3:7). The structure of 8 (0.011 mmol; 20% yield) was determined by spectroscopic analysis and verified by comparison with previous data (Dong et al, 1989;Gonzalez et al, 1991). 1 H-NMR (500 MHz, CDCl 3 ): d 6.43 (2H, s, H-2 0 and H-6 0 ), 3.94 (1H, m, H-2), 3.84 (6H, s, OMe-3 0 and -5 0 ), 3.81 (3H, s, OMe-4 0 ), 3.70 (1H, dd, J = 11.5, 2.5 Hz, H-1), 3.49 (1H, dd, J = 11.5, 6.5 Hz, H-1), 2.74 (1H,dd,J = 13.5,4.3 Hz,2.67 (1H,dd,J = 13.5,8.7 Hz,.…”

Six new compounds were isolated from the whole plant of Sonchus uliginosus, including three eudesmane-type sesquiterpenoids (1b,6a)-1,6,14-trihydroxyeudesm-3-en-12-oic acid g-lactone (1), (1b,6a)-1,6,14-trihydroxyeudesma-3,11(13)-dien-12-oic acid g-lactone (2), and (1b,6a)-1,6-dihydroxy-14-O-[(4-hydroxyphenyl)acetyl]eudesma-3,11(13)-dien-12-oic acid g-lactone (3), and three phenylpropane derivatives, 4-hydroxy-g,3,5-trimethoxybenzenepropanol (6), g,3,4,5-tetramethoxybenzenepropanol (7), and g,3,4,5-tetramethoxybenzenepropanol acetate (8), together with the two known compounds 4 and 5. The new structures were elucidated by means of spectroscopic methods, such as IR, EI-MS, HR-ESI-MS, 1D-and 2D-NMR, and by comparison of the spectroscopic data with those reported for structurally related compounds.Introduction. -The genus Sonchus, representing 8 species in China, has long been used as folk medicine for the treatment of fever, stasis, and inflammation, as well as for detoxication and mobilization of blood circulation [1]. In some species, eudesmanolides
