Eight new glycosides, morindaparvins P-W, were isolated from the butanol extract of the aerial parts of Morinda parvifolia. These new structures were elucidated by comprehensive spectroscopic analysis and by comparing the experimental and calculated electronic circular dichroism spectra. The butanol extract was observed to significantly reduce the levels of alanine aminotransferase, aspartate transaminase, and lactate dehydrogenase in the sera of mice with concanavalin A-induced hepatitis. At a concentration of 10 μM, five compounds (1, and 4-7) isolated from the butanol extract possessed hepatoprotective activities against the damage induced by acetaminophen in human HepG2 liver cancer cells.
