    Studysummary This study used phytochemical screening and FTIR spectroscopy with PCA to reveal slight chemical differences between two varieties of Eclipta alba, providing a method for their effective discrimination. Our plain-language summary of this paper — not a Tressless recommendation.
    The study aimed to effectively discriminate between two varieties of Eclipta alba, White Karisalanganni (WK) and Manjal Karisalanganni (MK), using phytochemical screening and a combination of FTIR spectroscopy and principal component analysis (PCA). The research found that the MK variety exhibited C=H and C=O stretches, indicating the presence of alcohol and ester functional groups, while the WK variety showed an alkyne group in its chloroform extract. These chemical differences, although slight, were significant enough to distinguish the two varieties. The findings supported the use of these methods for accurate authentication of the plant varieties for research, food, and pharmaceutical applications.
