“…As a result, most of the lead in the soil was bounded (generally over 80% of the total lead in the soil is fixed) and only a small part remains bioavailable for plants. This explains why in lead polluted soil the toxicity of plants was not proportional to the total lead content [28]. This finding also applies to chamomile tested on soil rich in organic matter, as at the end of E3-Pb experiment 96% of the added Pb content remains in the soil.…”

The paper presents a comparative bioaccumulation study between the growth of chamomile (Matricaria Chamomilla L.) exposed to toxic metals (Cd, Ni and Pb) and the growth of same plant species unexposed to metals. The soil was contaminated within three independent experiments with Cd, Ni and Pb at the intervention threshold value for sensitive use. Each of the toxic metal was added by watering the seeds, and subsequently the germinated plants. The experiments targeted the effects of soil pollution on the growth of chamomile during three months period. The results showed that in the first month of the study, all three metals accumulated in plants. After the seeds germination and plant growth, high Cd concentration in chamomile plants was detected. Moreover, Ni and Pb were detected in soil in the percentage of 96%. Overall, it was observed that chamomile plants were Cd accumulators at the tested concentrations of 6 mg/kg with no phytotoxic effects. Matricaria Chamomilla L. could be used in phytoremediation of polluted soils, with limitations of use for human consumption, except for the extracts.

“…Besides, micro-components in plants are associated with the arrangement cycles of dynamic synthetic elements, which permit their utilization for treating various disorders, for example, iron (Fe) supplement for blood-related disorders. The detrimental impact results from the reality that heavy metals migrate from soils, harvests, or plants, entering the food chain ( Antonijević et al, 2012 ), or by therapeutic applications from medicaments ( Cheng, 1955 ; Garcia et al, 2000 ; Başgel and Erdemoğlu, 2006 ; Adeyolanu et al, 2016 ). Considering the aforementioned points, the World Health Organization (WHO) has specified the permissible levels in crude plant material for the presence of heavy metals, thereby maintaining a stringent watch of negative effects on human well-being by plant utilization or its clinical use ( WHO, 1991 ; Zeiner et al, 2015 ).…”

Multielemental Analysis and In Vitro Evaluation of Free Radical Scavenging Activity of Natural Phytopigments by ICP-OES and HPTLC

et al. 2021

The phytopigments derived from ethnomedicinal plants employed as traditional medicines appear to be the simplest alternative for artificial radical colorants. This can be because of persistent use of synthetic dyes and their harmful impacts linked to human lives as well as to the ecosystem. The literature evidences clearly reveal the complications from growing demands of radical colorants from artificial origin. The planned analysis work hence focuses on screening of the fundamental composition of phytopigments, obtained from plant sources by subtle technique of ICP-OES, with axial plasma combined with nebulizer motor–assisted gas flow approach, utilizing microwave digester for complete digestion of phytopigments, thereby establishing the pigments being safe for consumption. Additionally, the observations from free radical scavenging activity using DPPH by HPTLC concluded that the natural pigments obtained from plant sources are rich in flavonoids with potent antioxidant property. Thus, an effort has been made through the developed ICP-OES methodology, to beat the distinct imprecise practice of food labeling, once natural pigments are utilized in a variety of additives, as food colorants with amounts of components detected as arsenic, lead, and metal, within specified limits of FSSAI, demonstrate and establish safety of natural foodstuff agents, as compared over hazardous synthetic azo dyes.

The study examined the phytochemical composition and heavy metals (Cu, Zn, As, Ni, Pb, Cd, Cr) present in Piper guineense from three markets in Lagos, Nigeria. The qualitative and quantitative analyses were carried out on both wet and dry samples using standard procedure. The results revealed the presence of bioactive compounds namely Alkaloids (53.12±0.14 and 37.66±0.00 mg/100g), Tannins (6.21±0. 13 and 4.12±0.00 mg/100g), Flavonoids (67.99±0.17and 23.98±0.00 mg/100g), Terpenes (14.63±0.18 and 8.95±0.00mg/100g), Saponins (5.99±0.14 and 4.76±0.00 mg/100g), Phenols(6.02±0.11 and 2.97±0.00 mg/100g) for dry and wet samples respectively from P. guineense collected from Igando while from Ikotun market the values are: Alkaloids (4.88±0.00 and 29.87±0.02 mg/100g), Tannins (4.44±0.00 and 2.97±0.02 mg/100g), Flavonoids (58.87±35.36 and 12.65±0.01mg/100g), Terpenes (6.98±0.00 and 4.96±0.02 mg/100g), Saponins (2.67±0.00 and 2.02±0.01 mg/100g), Phenols (4.55±0.00 and 1.88±0.02 mg/100g). Egbeda had Alkaloids (40.43±18.08 and 33.21±0.01), Tannins (9.06±4.17 and 4.08±0.00), Flavonoids (49.77±25.60 and 23.88±0.00), Terpenes (8.86±8.34 and 6.16±0.01 mg/100 g), Saponins (3.11±3.94 and 2.14±0.00 mg/100g) and Phenols (5.13±1.37 and 3.45±0.02 mg/100g). Values of phytochemicals (dry and wet weight) were significantly (p<0.05) higher in samples from Igando than samples of other markets. However, there was no significant difference among heavy metals detected in Piper guineense across the three markets. All the metal in the P. guineense were below WHO maximum permissible limit. The findings indicated that P. guineense collected from the markets are safe for consumption and good for medicinal use. However, efforts should be made by farmers planting P. guineense and seller of the vegetable to avoid further contamination either through soil or direct exposure to metals compounds.
