摘要
紫丁香。已知具有广泛的药用特性，包括紫外线吸收特性。本研究考察了季节对紫外光吸收特性的影响。美国cumini l .夏天收集树叶,冬天,秋天和雨季。分别制备叶片的丙酮提取物。提取液以10 nm为间隔，在200 ~ 400 nm波长范围内扫描获得吸收光谱。此外，还检测了多酚含量与紫外光吸收性能之间的相关性。结果表明，雨季叶的丙酮提取物对紫外线的吸收能力最强。雨季叶片多酚含量也较高。雨季小茴香叶丙酮提取物可作为防日晒剂制备防晒乳液。
Effect of Season on UV Absorbing Property of Syzygium cumini L. Leaves
Syzygium cumini Linn. is known to possess a wide range of medicinal properties including UV absorbing property. In the present study we have examined effect of season on UV absorbing property of S. cumini L. leaves. S. cumini L. leaves were collected in summer, winter, autumn and rainy seasons. Acetone extracts of the leaves were separately prepared. Extracts were used to get absorption spectra by scanning in the wavelength range 200 nm-400 nm at 10 nm intervals. Amounts of polyphenols in the leave extracts were also checked to note correlation, if any, between poly phenol content and UV absorbing property of S. cumini L. leaves. Results showed that acetone extract of the leaves of rainy season had maximum UV absorbing property. Polyphenol content of the leaves was also high during rainy season. Acetone extract of S. cumini L. leaves of rainy season may be used as anti solar agent in preparation of sun screen lotions.
