Bioactive constituents, sorption behaviour, antioxidant and antimicrobial activity of solar dried ajwain (Trachyspermum copticum L.) leaves

The stability of active compounds, sorption studies, and antioxidant antimicrobial activity solar-dried ajwain (Trachyspermum copticum L.) leaves were studied. Fresh leaf (FAL) on solar drying yielded (SDAL) was packed in polyethylene pouches for further studies. SDAL rich protein, fibre mineral matter. Active compounds such as β-carotene (17 89 mg/100 g) total chlorophyll (112 82 contents found FAL respectively. Similarly, higher ascorbic acid polyphenols content SDAL. Moisture isotherm studies indicated that the to be non-hygroscopic nature stable at room temperature. Antioxidant assayed by methanolic extract had better than FAL. ethanol evaluated disc diffusion method, which showed sensitive 20 µg/mL concentration Gram-negative positive bacteria. study encourages isolation characterization ingredients from their application foods nutraceuticals.
