    • The shade-dried leaves and stems (3 Kg) were extracted with methanol, and 54 g extract was obtained, which was partitioned with petroleum ether, EtOAc, and BuOH successively. The petroleum ether extract (23 g) was subjected to column chromatography (CC) over silica gel (200-300 mesh, 800 g silica gel) eluting with petroleum ether/EtOAc (10:0-0:10, gradients) to afford 3 fractions. Fraction 1 was separated on silica gel CC (300-400 mesh, 100 g) repeatedly, using n-hexane/acetone (10:1) as the eluent to yield pure 3 (12.3 mg) and 4 (8.3 mg). Fraction 2 was rechromatographed on a silica gel (300-400 mesh, 60 g) column with n-hexane/acetone (5:1) to give pure 5 (10.8 mg). Fraction 3 was rechromatographed on a silica gel (300-400 mesh, 30 g) column with n-hexane/acetone (3:1) to give pure 6 (8.7 mg) and 1 (14.5 mg).
