“…Similarly, in another study, 11 bivalents were reported both at diakinesis and metaphase stages in this species. [24] This has further corroborated the presently studied chromosome number of this species. Recently, Saggoo et al [6] studied seasonal variation in chiasma frequency among three morphotypes of E. alba and reported n = 11 in all the three forms which tallies with this chromosome count in three morphotypes of E. alba.…”

Aim: Present study deals with the morphological, cytological and phytochemical characterization of Eclipta alba. Materials and Methods: The plant materials (Eclipta alba whole plant) were collected from "Banga" region of Punjab, India. They were then studied for various morphological features, meiosis and phytochemicals. Fourier Transform Infrared Spectroscopy (FTIR) and Wavelength Dispersive X-Ray Fluorescence (WD-XRF) have been done to understand the different functional groups and elemental detail. Results and Discussion: Three morphotypes i.e., prostrate, semi-erect and erect has been described for Eclipta alba but with a constant chromosome number 2n=22 in all forms. Alkaloids, amino acid, carbohydrates, flavonoids, glycosides, gums and mucilage, phenolics, reducing sugars, tannins etc. were reported in aqueous and ethanol extracts of these forms. Further, Fourier Transform Infrared Spectroscopy has strengthened the phytochemical observations. Elements like Potassium, Calcium, Chlorine, Magnesium, Iron etc. were analyzed through Wavelength Dispersive X-Ray Fluorescence. Conclusion: Three morphotypes with same chromosome number have been described for Eclipta alba. The prostrate form seems to be better than other forms in terms of phytoconstituents and elements.

“…Cytologically, all information is of preliminary nature dealing mainly with its chromosome count (Singh 1951, Mehra et al 1965, Thakur and Singh 1968, Dey 1977, Trivedi and Kumar 1984. All studies have reported a chromosome number of 2n = 22 (Mohan et al 1962).…”

SummaryThe seeds of Eclipta alba have been successfully employed with different doses of X-ray irradiation to assess its effect on somatic chromosomes. The data obtained from the experimentally treated material have further been analysed with all the implications to understand the effects of radiation on the chromosome structure, behaviour and gene mutation. Although irradiation is known to induce chromosomal aberrations and mutation in many plants, its effect on Eclipta alba is not known. Data were obtained with regards to survival of seedlings and induced chromosomal anomalies in root tip cells. It may also be safely stated that experimental induction by physical means (X-rays) holds a clue to understanding the gene mutation and also the adaptability of the species in different environmental conditions. The result of experimental manipulation done as a part of the present investigation strengthens the contention that Eclipta alba in general is highly plastic and capable of forming populations through the adjustment of their genetic system.
