Many instances of a close relationship between folic acid and ascorbic acid have been reported in the literature. Johnson and Dana (1) have shown that ascorbic acid relieves many of the abnormalities noted in a folic acid deficiency syndrome. Woodruff and Darby (2) have reported that folic acid aids in correcting the abnormal tyrosine metabolism of the scorbutic guinea pig. Nichol and Welch (3,...

The effects of light illumination on the ascorbic acid content and growth of soybean sprouts were investigated. Among the six light qualities studied, ultraviolet light had the highest promoting effect on the ascorbic acid content in soybean sprouts, increasing it by 77.0% compared with the darkness control, while red light had the highest promoting effect on the growth of soybean sprouts, incr...

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 ...
