“…The xanthone C ‐glycoside mangiferin has been demonstrated to be the predominant constituent of mango stem bark extracts, displaying a multitude of pharmacological effects. Gallotannins, which have been detected in mango stem bark, pulp, kernel and leaves,8–13 are also likely candidates contributing to the described effects. However, information on their structures is rather limited and studies carried out so far date back to the 1960s and 1970s.…”

Polyphenolics were extracted from peels, pulp and kernels of mango fruits (Mangifera indica L. cv. 'Tommy Atkins') and characterized by high-performance liquid chromatography/electrospray ionization mass spectrometry. In the peel 18 gallotannins and five benzophenone derivatives were detected which were tentatively identified as galloylated maclurin and iriflophenone glucosides. Twenty-one and eight gallotannins were found in the kernels and pulp, respectively, whereas no evidence for the presence of benzophenone derivatives was obtained. Gallotannins quantified by the rhodanine assay amounted to 1.4 mg/g dm in the peels (expressed as gallic acid), while only small amounts (0.2 mg/g dm) were found in the pulp. In contrast, mango kernels contained 15.5 mg/g dm and thus proved to be a rich source of gallotannins.

“…Bacelo et al [17] reported that tannin-based adsorbents have a naturally high af inity for heavy metals, dyes, and other organic and inorganic pollutants in aqueous solution, indicating a need to investigate the application of these compounds for the removal of mono-aromatic hydrocarbons in water and waste gas steams. The sources for tannin based adsorbents are agricultural products such as leaves and tree barks that are often discarded as a waste in developing countries [18]. Removal of BTEX has traditionally been achieved by mixed cultures of bacteria and the use of fungi has been recognized only recently.…”

“…This is because many known tannin sources are agricultural products such as leaves and tree barks that are often discarded (El Sissi et al, 1965). Interestingly, solid winery waste, (especially red grape pomace which consists of grape skins, seeds, and stalks), has been highlighted as a possible source of tannins that could be explored for the synthesis of tannin-based adsorbents which can subsequently be applied to water treatment (Lu et al, 1999;Souquet et al, 2000;Ping et al, 2011;Ping et al, 2012).…”

BTEX (benzene, toluene, ethylbenzene, and xylene) compounds are common water resource and potable water pollutants that are often left undetected and untreated by municipal treatment systems in spite of the negative repercussions associated with their ingestion. The US EPA has classified these pollutants as priority pollutant, yet they are persistently present in a variety of water resources. In this review paper, we highlight the sources and reported concentrations of BTEX compounds in water and explore historical remediation techniques that have been applied such as bioremediation and natural attenuation. We also highlight emerging possibilities and future directions for remediation techniques, such as nanotechnology-based materials and novel green materials (tannins) that can be applied to ensure removal of these compounds in water.
