Changes in phospholipids, fatty acids, oxidative enzymes, phenolics and protein levels during growth of normal and habituated tissues of Cocculus pendulus.

ABSTRACT

Cultures of C. pendulus were maintained on hormone free and hormone supplemented (NAA 1.0 mg/l and kinetin 0.5 mg/l) Murashige and Skoog medium. During the growth period, hormone free cultures had higher phenolic content, polyphenol oxidase activity and less protein content, peroxidase and IAA oxidase activity. Activity of all the three oxidising enzymes and phenolic content were high at 16 days growth. Total lipid content was higher (2.7-folds at 15 days) in hormone free cultures. Phospholipid content of both cultures was not markedly dissimilar except PC and DGDG contents. Thus it is evidenced that both the tissues were similar metabolically.
