Abstract

This study was carried out for investigate that physiological activity, quantification and qualitative were sinigrin of Dolsan leaf mustard pickle (DLMP) during storage. sinigrin contains high amounts of nutritional and medicinal compounds, which are important for maintaining optimum health. ACE inhibitory activity was ranged between 43.2 and 79.4%. DLMP methanol extracts demonstrated highest ACE inhibitory activity at 79.4% on day 14, whereas DLMP ethanol extracts demonstrated highest Angiotensin I-converting Enzyme (ACE) inhibitory activity of 43.2% at day 0. The ${\alpha}-glucosidase$ inhibitory activity of positive control 0.02% (v/v) acarbose was 78%. The DLMP methanol extracts had the highest ${\alpha}-glucosidase$ inhibitory activity at 64.0% on day 14, whereas DLMP ethanol extracts had the lowest ${\alpha}-glucosidase$ inhibitory activity of 42.8% at day 28. Sinigrin was high in DLMP methanol extracts at $49.55{\mu}g/ml$ on day 14 of storage. Sinigrin standard was eluted at 2.73 min and MS analysis was m/z 283.03 along with fragment ions at m/z 204 and 149.06. These data show that sinigrin formed desulfo-glucosinolates $[M-SO_3-2H_2O+K+2H]^+$. Sinigrin concentration increased until day 14 and then decreased after that. DLMP methanol extracts had consistently higher sinigrin concentration than DLMP acetonitrile extracts during 28 days of storage.
