Propensity of Tagetes erecta L., a Medicinal Plant Commonly Used in Diabetes Management, to Accumulate Perfluoroalkyl Substances

Abstract

It has been extensively demonstrated that plants accumulate organic substances emanating from various sources, including soil and water. This fact suggests the potentiality of contamination of certain vital bioresources, such as medicinal plants, by persistent contaminants, such as perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), and perfluorobutane sulfonate (PFBS). Hence, in this study, the propensity of Tagetes erecta L. (a commonly used medicinal plant) to accumulate PFOA, PFOS, and PFBS was determined using liquid chromatography/tandem mass spectrometry (LC–MS/MS-8030). From the results, PFOA, PFOS, and PFBS were detected in all the plant samples and concentration levels were found to be 94.83 ng/g, 5.03 ng/g, and 1.44 ng/g, respectively, with bioconcentration factor (BCF) ranges of 1.30 to 2.57, 13.67 to 72.33, and 0.16 to 0.31, respectively. Little evidence exists on the bioaccumulative susceptibility of medicinal plants to these persistent organic pollutants (POPs). These results suggest that these medicinal plants (in particular, Tagetes erecta L., used for the management of diabetes) are also potential conduits of PFOA, PFOS, and PFBS into humans.

Extraction of lutein dye from Tagetes erecta garland waste for green dyeing of hemp fabric using response surface methodology

“…Figure 6 illustrates the effect of dyebath pH (3)(4)(5)(6)(7)(8)(9)(10)(11)(12) on K/S values of the dyed fabrics. It is observed that the optimum K/S is obtained at acidic pH of 4.…”

“…The main colorant components of marigold flower are carotenoid compounds such as lutein and lutein esters. Lutein (C40H56O2) (Figure 2) is a bright yellow xanthophyll pigment and is very popularly used in medical and food industries [7,8]. A study has shown that lutein is a pigment, which is water soluble and behaves like a dye [9].…”

Medicinal Plants Threatened by Undocumented Emerging Pollutants: The Sub-Saharan African Viewpoint

“…Voigt (Benin, Kenya, Togo and Uganda), Ximenia americana L. (Guinea, Kenya, South Africa and Zambia), and Zanthoxylum chalybeum Engl (Kenya, Rwanda, Uganda and Zambia) [11]; and for the management of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) in the sub-Saharan region, Ximenia americana has been in use (Zambia, Uganda and Kenya), and Azadirachta indica (Uganda and Kenya) [89][90][91]. Similarly, numerous studies have highlighted the antidiabetic potential of several hundreds of sub-Saharan African medicinal plants [4].…”

“…These plants are an important mode of combat to serious illnesses and diseases in the world [3]. These crops and their derivatives are used for healing by various populations, and in extreme scenarios, these plants have been chosen as natural alternatives or substitutes to their orthodox counterparts [4]. Reported evidence has indicated that these natural products and their derivatives account for an estimated more than 50% of all the drugs used globally [5].…”

High level of intraspecific divergence and low frequency of RNA editing in the chloroplast genome sequence of Tagetes erecta

“…Plants belonging to this genus have important medicinal value. Several studies have suggested that T. erecta has the potential to treat ailments, such as diabetes mellitus (Mudumbi et al 2019). In particular, the flowers have been used to cure eye diseases, colds, conjunctivitis, coughs, ulcers, bleeding piles, and to purify the blood (Hemali and Sumitra 2014).…”
