reynosin and mokko-lactone

To study the chemical constituents of Dolomiaea souliei.. Various chromatographic techniques were adopted to separate the constituents, and the spectrum analysis was made to identify their structures.. Seventeen compounds were isolated and identified as: dehydrocostus lactone (1), costunolide (2), mokko lactone (3), santamarine(4), reynosin (5), 4alpha-hydroxy-4beta-methyldihydrocostol (6), sulfocostunolide A (7), beta-costic acid (8), beta-cyclocostunolide (9), vladinol A (10), ursolic acid (11), betulinic acid (12), betulin (13), dibutyl terephthalate (14), dibutyl phthalate (15), uridine (16), and emodin (17).. Compounds 6-9 and 12-17 were obtained from this genus for the first time, and compound 11 was obtained from this plant for the first time.
