“…The vitamin concentrations of T. occidentalis grown on gas flared remediated soil were higher than those on non-gas flared soil for 7.1 t ha −1 and 13.9 t ha −1 biochar treated plants, suggesting that 13.9 t ha −1 biochar treatment promoted vitamin synthesis. The result agrees with that of Lou et al [ 29 ] who reported increased vitamin C concentration in cabbage grown with an aqueous extract of maize straw biochar.…”

This study evaluates the effects of remediation of gas flared soil by biochar on the nutritional composition of cultivated Telfairia occidentalis leaves, relative to non-gas flared soil. Gas flared soils are degraded due to the presence of heavy metals, noxious gases, carbon soot and acidic rain. Biochar produced from oil palm fibre was applied at five different amounts: 0 t ha−1, 7.1 t ha−1, 13.9 t ha−1, 20.9 t ha−1 and 28.0 t ha−1 to containerized soils (both gas flared and control soil), inside a greenhouse, which were allowed to mineralize for two weeks. Two viable seeds of T. occidentalis per replicate were sown. After eight weeks of growth, leaves were harvested, dried and chemically analyzed. Application of biochar significantly increased leaf ash and crude fibre content of Telfairia occidentalis. Plants from soil treated with 13.9 t ha−1 of biochar had the highest concentrations of vitamins A, B1, B2, B6, C and E irrespective of soil type. Maximum increase in leaf vitamin and mineral content was obtained from leaves cultivated on gas flared soil treated with 13.9 t ha−1 and 7.1 t ha−1 of biochar respectively. The results show that biochar treatment can increase leaf mineral concentrations and that this effect is dependent on the amount of biochar application.

“…Ascorbic acid (Vitamin C) is known for its high antioxidative activity and is essential for proper heart functioning and maintaining skin health. Our result showed that the T. populnea leaf contained 44.3 ± 5.5 mg 100 g −1 DW of ascorbic acid (Table 1), which was higher than the medicinal plant Cymbopogon citratus (Uraku et al, 2015), suggesting that the vitamin C content in the leaves of T. populnea is enough for fulfilling the daily requirements of a healthy individual. Another important antioxidant compound is carotenoids.…”

Phytochemical profiling, polyphenol composition, and antioxidant activity of the leaf extract from the medicinal halophyteThespesia populneareveal a potential source of bioactive compounds and nutraceuticals

The present study evaluated the phytochemical constituents, nutritional attributes, and the antioxidant capacity of the medicinal halophyte Thespesia populnea. The metabolite profiling by GC‐QTOF‐MS analysis identified 37 metabolites among which sucrose, malic acid, and turanose were the most abundant. A total of 18 polyphenols and 17 amino acids were identified by the HPLC‐DAD analysis. The most abundant polyphenols in T. populnea were gallic acid, catechin, and myricetin. Other polyphenols like protocatechuic acid, epigallocatechin gallate, rosmarinic acid, ellagic acid, rutin, and naringenine were also detected in ample amounts. The leaf extract demonstrated higher antioxidant as well as lipid peroxidation inhibition activities. A correlation analysis revealed a positive correlation between the antioxidant capacity and the phenolic compounds viz. gallic acid, catechin, myricetin, quercetin, apigenin, cinnamic acid, and coumarin which indicates that these phenolic compounds are the main contributors of the antioxidant potential of T. populnea. The results of this study establish T. populnea as a potential source of nonconventional functional food. Practical applications The data presented here indicate that T. populnea can be considered as a nonconventional functional food and potential source of energy, antioxidants, minerals, essential amino acids, and bioactive compounds in herbal formulations, food supplements, or nutraceuticals. The metabolites identified from this halophyte have pharmacological and nutraceutical potentials, suggesting T. populnea as an ideal candidate for application in the food and phytopharmaceutical industries to produce health‐promoting products, functional foods, and herbal medicines.

“…The results of the study showed high concentrations of retinol, niacin and folic acid with low concentration of ascorbic acid and thiamin. The high concentrations of retinol, niacin and folic acid obtained in the study were higher than that obtained from Cymbopogon citratus leaves according to Uraku et al (2015a) [4]. The presence of retinol in high concentrations is an indication that the leaves could be a good source for growth and development, maintenance of immune system and good vision [17,18].…”

.01). The result also recorded high levels of retinol (184.00±0.00), niacin (54.00) and folic acid (28.40±0.00) with low levels of ascorbic acid (0.08±0.01), thiamin (0.24±0.00), riboflavin (0.66±0.00) and tocopherol (1.03±0.00). The higher amounts of the proximate contents and vitamins indicated that besides the leaves are being used as traditional medicinal, this herb can serve as good source of nutrients to human as well.
