Composition of polyphenols of asparagus spears (Asparagus officinalis) and their antioxidant potential

Mineral Nutrient Composition of Green and White Asparagus Spears

Mineral nutrients were determined in green and white ‘Jersey Giant’ asparagus (Asparagus officinalis L.) spears grown in 1991 near Booneville, Ark. Green spears had higher concentrations of tissue N, K, P, S, Na, and Zn; similar levels of Fe, Al, and Cu; and lower levels of NO3 than white spears grown under opaque plastic rowcovers or under sawdust mulch. Levels of Ca, Mg, and Mn were higher in...

Antioxidant Potential of Asparagus adscendens

Root Residue Amendment on Varietal Allelopathy and Autotoxicity of Replanted Asparagus (Asparagus officinalis L.)

This study evaluated the allelopathic potential and autotoxic interference with growth and nutrient uptake of two asparagus varieties; UC157 (U) and Gijnlim (G) from USA and Europe, respectively. The two varieties were cultivated in a continuous replanting system in different rotational patterns with soil amended by asparagus root residues, and unamended soil (control) under greenhouse conditio...

Life Table and Consumption Capacity of Corn Earworm, Helicoverpa armigera, Fed Asparagus, Asparagus officinalis

The life table and consumption rate of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) reared on asparagus, Asparagus officinalis L. (Asparagales: Asparagaceae) were studied under laboratory conditions to assess their interaction. Development, survival, fecundity, and consumption data were analyzed by the age-stage, twosex life table. This study indicated that asparagus is a natural host...

Antiradical capacity and polyphenol composition of asparagus spears varieties cultivated under different sunlight conditions.

BACKGROUND Asparagus officinalis has a high nutritional value. Asparagus is rich in a number of bioactive compounds, mainly flavonoids (quercetin), glutathione, vitamin C, vitamin E, fructans (inulin and fructooligosaccharides) and phytosterols (b-sitosterol). These compounds may play an important role in human health. The purpose of this study was to examine the antioxidant potential and polyp...
