isolation was completed by preparative reversed-phase HPLC.
New compounds 1 (26.2 mg) and 2 (35.3 mg) were isolated from
B4. Daturametelin B (6) (100.6 mg) was isolated from B1 and B2
and daturametelin D (7) (50.9 mg) was isolated from B3. Daturametelin
A (8) (16.8 mg) was isolated from B5. All known compounds
were identified by comparing spectroscopic data with
reported values.
