Effect of processing on beta-carotene content in forest green leafy vegetables consumed by tribals of south India

Carotenoid composition and retinol equivalent in plants of nutritional and medicinal importance: Efficacy of β-carotene from Chenopodium album in retinol-deficient rats

“…In this study, higher contents of lutein and b-carotene were recorded in Allium schoenoprasum (8.2 and 5.4 mg/100 g fresh weight). b-Carotene content of amaranth leaves ranged from 2.3 to 14.7 mg/100 g fresh weight in the present study and was similar to those in reports of Rajyalakshmi et al (2001) and Singh et al (2001) who reported 10.1 and 5.4 mg/100 g fresh weight, respectively. b-Carotene contents of C. album (120 mg) and C. benghalensis (95.7) were comparable with those reported by Raju et al (2007).…”

“…Moreover, carotenoid content is known to vary in plant foods due to differences in characteristics of cultivars, climate and growing conditions (Aizawa & Inakuma, 2007). Currently, only limited information is available on the carotenoids present in green leafy vegetables produced and grown (wild) from different parts of India (Bhaskarachary, Rajendran, & Thingnganing, 2008;Lakshminarayana, Raju, Krishnakantha, & Baskaran, 2005;Raju, Varakumar, Lakshminarayana, Krishnakantha, & Baskaran, 2007;Rajyalakshmi et al, 2001;Singh et al, 2001) and the information on plants used for Ayurvedic medicinal purposes is even more scarce (Raju et al, 2007;Rajyalakshmi et al, 2001). Thus, the current study was undertaken to determine the carotenoid profile and vitamin A activity (as retinol equivalents) of selected leafy green vegetables and plants of medicinal importance found in India.…”

β-carotene Content of Some Commonly Consumed Vegetables and Fruits Available in Delhi, India

“…Studies conducted in south India have also reported values (5760-8600 µg/100 g) of β-carotene in amaranth leaves nearly similar to values of present study [11,24,25]. While, one study conducted in Mysore, India has even reported higher value as 18670 µg of β-carotene/100 g of amaranth leaves than present study [21].…”

“…There are many edible varieties of amaranth in different parts of the world. It has been reported that Amaranthus viridis had β-carotene content in the range of 3200 µg/100 g to 58950 µg/100 g [11,[19][20][21]24,27]. It has been reported that other species like Amaranthus cruentus from south India had 7600 µg of β-carotene content per 100 g [27] while Amaranthus tricolor had 1601 µg to 9600 µg of β-carotene/100 g reported in other studies [10][11]19,[27][28][29][30].…”

Chemical Composition and Hepatoprotective Effects of Polyphenolic Fraction From Rivea Hypocrateriformis in Paracetamol Induced Liver Damage in Wistar Albino Rats

“…Cooked leaves of this plant are used as vegetable curry by the tribals of India. The plant has maximum vitamin An activity and has the capacity of maximum (75 to 98%) retention of β-carotene upon processing [16,17]. Desmethyl bergenin hemihydrate is a naturally occurring isocoumarin isolated from this plant [18].…”
