タより新規物質と同定された。The dried leaves of Plumeria actifolia Boil are powdered, extracted with a 90% ethanol solution, and compressed under reduced pressure to obtain a crude extract. Next, the obtained crude extract is subjected to adsorption chromatography and sequentially eluted with water-methanol solvent. For each of the obtained fractions, the crude crystals obtained from the fraction with strong growth inhibiting activity against cultured Yoshida sarcoma cells are treated with ethyl acetate to separate into ethyl acetate soluble portion and sparingly soluble crude crystals. The obtained ethyl acetate soluble portion was acetylated with acetic anhydride-pyridine, and then separated and purified using high performance liquid chromatography. JeOH-KO
Deacetylation is performed with H to restore the original compound and isolate three types of compounds. One of these compounds, 2ffi, was identified as a known substance based on mass spectrum and NMR spectrum data, while the other one was identified as a new substance based on its spectrum data.
