Chemical composition, angiotensin‐converting enzyme‐inhibitory activity and antioxidant activities of few‐flower wild rice (Zizania latifolia Turcz.)

Abstract

Both the stem and leaf sheath extracts exhibited good antioxidant properties, while good ACE-inhibitory activity was detected only in the phosphate buffer solution extracts of the stem. Few-flower wild rice could be processed into formula feeds for fish, poultry, etc. or functional foods for persons with high blood pressure.

Antioxidant capacity and angiotensin I converting enzyme inhibitory activity of a melon concentrate rich in superoxide dismutase

“…The IC 50 value was 2.4 ± 0.1 mg/mL. This inhibition was high compared to that of few-flower wild rice as demonstrated by Qian and colleagues (Qian et al, 2012). Indeed, they have shown that IC 50 value of the stem extracts was approximately 38.54 mg/mL.…”

Comparative Transcriptome Profiling of Chilling Stress Responsiveness in Two Contrasting Rice Genotypes

“…Proline and MDA concentrations were measured according to the protocol of Shukla et al [21]. Antioxidant enzyme activity, including SOD, POD, CAT, and GR, were determined following previously reported methods [22], and ascorbic acid and GSH concentration were determined as described in Qian et al [23].…”

Impact of high hydrostatic pressure on non-volatile and volatile compounds of squid muscles

“…The concentrations of Ca, K, Mg and Na in squid samples were measured using an inductively coupled plasma optical emission spectrometer (OPTIMA-7000DV, Perkin-Elmer, Waltham, MA) according to the method described by Qian et al (2012). The phosphate and chloride concentrations were determined using an 882 ion chromatograph system (Metrohm, Riverview, FL) equipped with a high capacity anion exchange analytical column (Metrosep A Supp 5, 250 mm  4.0 mm).…”
