Detached bean (Phaseolus vulgaris) and strawberry (Fragaria) fruits fed l-gulono-1,4-lactone or l-galactono-1,4-lactone convert this compound, in part, to l-ascorbic acid. When l-galactono-1,4-lactone is given as a 0.25% solution to detached bean shoots, the ascorbic acid content is tripled in less than 10 hours. l-Gulono-1,4-lactone is only 5 to 10% as effective as its epimer. Experiments with...

Pleurotus ostreatus better known as oyster mushroom is widely cultivated and consumed as food in Malaysia. The present study aims to assess the antioxidative potential and total phenolic content of P. ostreatus aqueous extract. The antioxidant activities were evaluated against DPPH and ABTS radical-scavenging activity, ferric-reducing antioxidant power (FRAP) and β-carotene-linoleate bleaching ...

the physical and physiological characteristics of sarawak pineapple were studied at five different stages of growth from one to five months after anthesis. changes in fruit length, diameter, pulp color, pulp firmness, ph, total soluble solids, titratable acidity, ascorbic acid content and antioxidant activity were monitored. the sarawak pineapple exhibited a sigmoid growth pattern during fruit ...

The present paper deals with the influence of starvation on fish which has great ability to adapt in starvation stress. In the present investigation, the effect of prolonged food deprivation on ascorbic acid contents of gonadal tissues has been observed in both the sexes of Clarias batrachus. The level of ascorbic acid content was found relatively higher in males than in females. The testes sho...
