Estimation of Water-Soluble Vitamin B-Complex in Selected Leafy and Non-Leafy Vegetables by HPLC Method

Estimation of Vitamins B-Complex (B2, B3, B5 and B6) of Some Leafy Vegetables Indigenous to Bangladesh by HPLC Method

The current experiment was conducted for the simultaneous determination of several water-soluble vitamins like riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5) and pyridoxine (vitamin B6) in five highly consumed local leafy vegetables named as bottle gourd leaves (Lagenaria vulgaris) (local name Lau shak), green amaranth leaves (Amaranthus viridis) (local name Data sh...

Nutritional composition of selected green leafy vegetables, herbs and carrots.

Six green leafy vegetables and herbs - spinach, amaranth, bengal gram, cauliflower, mint, coriander and carrots - were analyzed for moisture, protein, ascorbic acid, beta-carotene, total iron, ionizable iron (as % of total iron) in vitro iron (% of total iron), copper, manganese and zinc. Moisture content of the leaves and carrots varied from 75.1 percent (bengal gram) to 95.4 percent (carrot) ...

Nitrate accumulation in leafy vegetables and its relationship with water

Present studies show that nitrate accumulation is the major factor influencing the water uptake by vegetables, but there is lack of knowledge on how the relationship between nitrate and water concentrations in different vegetable tissues. We determined nitrate accumulation and water content in vegetables of rape, Chinese cabbage, and spinach under different nitrogen levels (experiment I), 29 sp...

Development of a HPLC - DAD - MS / MS method for simultaneous determination of 1 fat - and water - soluble vitamins in green leafy vegetables

Perchlorate and nitrate in leafy vegetables of North America.

In previous studies trace levels of perchlorate were found in lettuce (Lactuca sativa L.) irrigated with Colorado River water, which is contaminated with low levels of perchlorate from aerospace and defense related industries. In this paper, we report the results of a survey conducted across North America to evaluate the occurrence of perchlorate in leafy vegetables produced outside the lower C...
