Variability in phytochemical and cytological characteristics of six cultivars of Codiaeum variegatum (L.) Blume (Euphorbiaceae). Six cultivars of Codiaeum variegatum (Spirale, Royal, Broad Spotted Guinea, Punctatum, Sunray and Royal-like) were chemically and cytologically screened to evaluate their therapeutic potentials, values and variability. The shoots were relatively rich in alkaloids, cardiac glycosides, saponins, tannins, cardenolides, steroids, and phyllates. Flavonoids, phlobatannins, phenols and anthraquinones were sparingly present. Anthraquinones and cardenolides were absent in 'Spirale' while 'Sunray' lacked tannins, phlobatannins and phenols. Terpenes were found only in 'Sunray'. Overall, alkaloids were the most abundant with the highest mean value of 1.46% in 'Royal' while flavonoids and anthraquinones were trace, 0.002 & 0.003%, in 'Sunray' and 'Royal-like'. Five pigments, carotene (yellow-orange), phaeophytin (grey), chlorophyll a (blue-green) and b (green), and xanthophyll (yellow) were determined. 'Spirale', 'Royal', 'Broad Spotted Guinea' and 'Punctatum' had diploid chromosme number of 2n=60 while 'Sunray' and 'Royal-like' possessed 2n=30 and 24 respectively. Genetic mutation and chromosomes variability could account for the wide morphological variation and morphotypes in this plant species. Log in to add this item to your schedule
