Abstract:
Object To study the chemical constituents from the stem of Photinia parvifolia (Pritz.) Schneid. Methods The compounds were isolated by silica gel column chromatography and their structures were elucidated by means of spectral analysis. Results Seven compounds were identified as lupeol (Ⅰ), ?-sitosterol (Ⅱ), betulinic acid (Ⅲ), pyracrenic acid (Ⅳ), epicatechin (Ⅴ), daucosterin (Ⅵ), pruasin (Ⅶ). Conclusion Compounds Ⅰ, Ⅲ-Ⅵ are isolated from the plants of Photinia Lindl. and compounds Ⅱ and Ⅶ are isolated from P. parvifolia for the first time. Compound Ⅳ shows anticancer effect.
