Background: Lantana camara, Parthenium hysterophorus, Ageratum conyzoidus and Ricinus communis are underutilized plants. These plants are traditionally used in many health related areas.
The context and purpose of the study: To investigate the photochemicals present in underutilized plants Lantana camara, Parthenium hysterophorus, Ageratum conyzoidus and Ricinus communis:
Methods: Qualitative, quantitative screening, compound identification by UV-VIS method and Fluorescent spectroscopy and FT-IR based identification of functional groups of active chemical components were studied. Organic solvents leave extracts (ethanol, methanol, acetone) were tested for availability of secondary metabolites.
Results, the main findings: UV-VIS spectrum showed different peaks with different absorption in all plants. The method of quantitative analysis in UV-VIS spectrum was proved in terms of linearity, LOD and LOQ AND various secondary metabolites were detected in the plant extracts. Florescent analysis confirmed the presence of secondary metabolites like alkaloids and phenolics. The FT-IR spectrum values indicated the presence of C-H stretching, O-H bending, C-C stretching and confirmed the presence of alcohols, phenols, alkanes and amines in acetone extracts.
Conclusion: The results confirmed the fact that these plants poses important bioactive components useful for human mankind, so further investigation may needed.
