Laterite Integrated Persulfate Based Advanced Oxidation and Biological Treatment for Textile Industrial Effluent Remediation: Optimization and Field Application.

This study investigated a combined approach of a persulfate-based advanced oxidation process (AOP) followed by biological treatment of a textile industrial effluent. The effluent from the textile industry is primarily composed of various dyes in varying concentrations, resulting in high chemical oxygen demand (COD) and biological oxygen demand (BOD). The model pollutant rhodamine B (RhB) was used in the optimization studies.

Quorum sensing inhibitory potential and in silico molecular docking of flavonoids and novel terpenoids from Senegalia nigrescens.

Ethnopharmacological Relevance: Senegalia nigrescens is used in traditional medicine for the treatment of dysentery and convulsions.

Aims Of The Study: This study was aimed at identifying bioactive compounds from S. nigrescens and carrying out in vitro and in silico anti-quorum sensing studies on the compounds.

PHYTOCHEMICAL, ELEMENTAL AND BIOTECHNOLOGICAL STUDY OF .

Background: Existing populations of (Lauraceae) are rapidly declining as a consequence of their substitutive use for . The uncontrolled and excessive removal of the bark and roots of this species has led to the death of many of these plants and may eventually result in its depletion in the natural habitat.

Materials And Methods: The secondary metabolites from the leaves and fruits of were extracted using solvents of various polarities, isolated using column chromatography and identified using spectroscopic techniques.

Phytochemical Analysis with Antioxidant and Cytotoxicity Studies of the Bioactive Principles from Zanthoxylum capense (Small Knobwood).

Background: Zanthoxylum capense (small knobwood) is a South African species known for a wide range of anecdotal uses. However, there is a dearth of information on its phytoconstitutional make-up, specifically its knobs, with only a few reports on the bioactive compounds that could justify its ethnomedicinal use.

Objectives: This work aimed to identify the active principles in Z.

Impact of spiked concentrations of Cd, Pb, As and Zn in growth medium on elemental uptake of Nasturtium officinale (Watercress).

This study is aimed at investigating the impact of water quality on the uptake and distribution of three non-essential and toxic elements, namely, As, Cd and Pb in the watercress plant to assess for metal toxicity. The plant was hydroponically cultivated under greenhouse conditions, with the growth medium being spiked with varying concentrations of As, Cd and Pb. Plants that were harvested weekly for elemental analysis showed physiological and morphological symptoms of toxicity on exposure to high concentrations of Cd and Pb.

GA3-mediated dormancy alleviation in the reputed African potato, Hypoxis hemerocallidea.

Background: Hypoxis hemerocallidea, arguably the most well-known medicinal species in South Africa, has been the subject of intensive harvesting from the wild leading to recent conservation concerns. The seeds of this species do not propagate easily and can lie dormant for up to twelve months.

Materials And Methods: In the in vitro germination experiments water, acid and chemical pre-sowing treatments were performed to determine the germination response of this species in both light and dark conditions.

Comparison of the selected secondary metabolite content present in the cancer-bush Lessertia (Sutherlandia) frutescens L. Extracts.

Extracts of in vitro leaves, field leaves and seeds of the leguminous plant Lessertia frutescens were analyzed using spectrophotometric and gravimetric methods, to the effect of quantitative comparison of their phenolic, flavonoid, alkaloid and saponin contents. As compared to the field leaves and seeds, saponins were found to be most abundantly represented in in vitro leaves, followed by phenolics, flavonoids and alkaloids. The extracts were also qualitatively analyzed so as to evaluate the presence of other phytochemicals of medicinal interest.
