Objective:To study the morphology,biochemistry and bioactivity of the epidermal glands of the glandular morphotype of Christella parasitica(***)(L.) ***: Morphological studies on epidermal glands were earned out by using light microscope and scanning electron *** prepare the extract,the shade-dried fronds of glandular morphotype were soaked in *** antibacterial studies paper disc method was followed by using various pathogenic ***:Detailed micromorphological,phytochemical and bioactivity studies on a medicinal fern ***(L.) *** its inlraspecific variation in antibacterial *** presence or absence of the epidermal glands was the key factor for antibacterial activity in the morphovariants of this *** epidermal glands were orange-coloured,stalked and elongated ones of about 84.2μm×45μm,and distributed on the undersurface of cosla,coslules and veins in croziers,young and mature *** of glands varied from 15/cm on costa in mature leaves to 140/cm on costules in *** acetone extract of the glands showed antibacterial activities and also toxic effect against mosquito larvae and tadpoles of *** phytochemical analysis and HPLC studies of the gland extract showed the presence of various kinds of terpenoids,alkaloids,tannins,saponins and flavonoids in ***:The present study shows that epidermal glands of the glandular morphotype of C. parasitica(L.) *** several bioactive compounds and such rare moiphovariant should be conserved in *** next step is to isolate the pure compounds and to screen the bioactivity of individual compounds of the epidermal glands.
