The methanol extract was filtered and concentrated under reduced pressure at 40 ° C to obtain an extract. This was suspended in water, and the suspension was subjected to solvent fractionation successively using hexane, chloroform and ethyl acetate. Since the activity was confirmed in the chloroform and ethyl acetate fractions of the fractions, the chloroform fraction of these solvent fractions was subjected to chromatography (CC) using silica gel and RP-18 column. The chloroform fraction (214 g) was separated by using a silica gel column, and dichloromethane-methanol was selected as an eluting solvent, and gradient elution (100: 0 → 0: 100) was performed to obtain 19 small fractions. The fraction (6.3 g) was subjected to silica gel CC. The fractions 10 (1.87 g) were fractionated into silica gel CC (mobile phase: hexane-acetone (8: 1)) in a small fraction of the separated fractions, and the fraction eluted with hexane- And finally RP-18 CC (mobile phase: acetonitrile-water (1.5: 1)) to yield 523 mg of compound MAC 6.4 (formula I).
