Description 278-284
The stability of active compounds, sorption studies, and antioxidant and antimicrobial activity of solar-dried ajwain
(Trachyspermum copticum L.) leaves were studied. Fresh ajwain leaf (FAL) on solar drying yielded solar-dried ajwain leaf
(SDAL) and was packed in polyethylene pouches for further studies. SDAL was rich in protein, fibre and mineral matter.
Active compounds such as β-carotene (17 and 89 mg/100 g) and total chlorophyll (112 and 82 mg/100 g) contents were
found in FAL and SDAL respectively. Similarly, higher ascorbic acid and polyphenols content were found in SDAL.
Moisture sorption isotherm studies indicated that the SDAL was found to be non-hygroscopic in nature and stable at room
temperature. Antioxidant activity as assayed by methanolic extract indicated SDAL had better activity than FAL. The
ethanol extract of FAL and SDAL was evaluated for antimicrobial activity by disc diffusion method, which showed that the
extract was sensitive at 20 μg/mL concentration on Gram-negative and positive bacteria. The study encourages the isolation
and characterization of active ingredients from FAL and SDAL and their application in foods as nutraceuticals.
