Abstract

  Ageratum conyzoides Linn (A. conyzoides L.), a medicinal plant, is known to possess a wide range of pharmacological activities. Recently we have noticed UV absorbing property of A. conyzoides L. leaves. Since pharmacological activity of a plant depends on season, in the present study we have examined effect of season on UV absorbing property of A. conyzoides L. leaves.. Leaves of A. conyzoides L. were collected in autumn, winter, summer and rainy season. Ethanol extracts of the leaves of different seasons were prepared separately. Extracts were used to get absorption spectra by scanning in the wavelength range from 200 nm to 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 A. conyzoides L. leaves. Results showed that ethanol extract of A. conyzoides L. leaves of summer had maximum UV absorbing property. Polyphenol content of the leaves was also maximum during summer. Ethanol extract of A. conyzoides L. leaves of summer may be used as anti solar agent in preparation of sun screen lotions.

Keywords: Ageratum conyzoides Linn. Leaves; UV Absorbing Property; Seasonal Effect; Polyphenols; Sun Screen Lotion
