The accumulation of catecholamines in leaves of some plants may relate to stress. Furthermore, the noradrenaline level in the peel of banana fruits increased from 5.1–6.2 in unmatured and yellow matured to 15.2 µg/g of fresh mass in yellow-black supermatured fruit, and the increase in the pulp from 2.5 in yellow matured to 10.1 µg/g of fresh mass in supermatured fruit is associated with oxidative processes during ripening (Foy and Parratt 1960). Feng with coauthors (1961) found a high concentration of noradrenaline in the medicinal plant Portulaca oleracea. In the ripening or overripened state, the concentration of noradrenaline increases two- to fourfold compared with unripe fruits. In plants that are able to respond to mechanical stimuli with motor activity, such as Albizia julibrissian and Mimosa pudica, noradrenaline accumulates in motor organs and axes of leaves (Applewhite 1973). Dopamine has an exogenous defensive reaction to stress connected with alkali salt damage (Jiao et al. 2019) or drought (Gao et al. 2019).

Several studies have been conducted to develop the edible products based on CSPI (Kumar 2019). Apart from the nutritional quality, the ability CSPI to be incorporated in food system plays important role. This ability can confirm by evaluating the protein for the functional properties such as water holding capacity, oil holding capacity, foaming properties, and emulsifying properties. Another important property of the protein is its solubility at various pH, this is critical for its use in acidic and alkaline foods. These properties have been evaluated by various researchers (Tsaliki et al.2002; 2004). However, functional properties of the proteins vary as per environmental factors, processing conditions and extraction methods. The functional and physicochemical properties of CSPI obtained from hot-pressed solvent extraction, cold-press solvent extraction and subcritical fluid extraction of CSM shows good oil/water absorption capacity, emulsifying properties, foaming properties, fluorescence intensity, surface hydrophobicity which suggested their potential applications in food industry (Ma et al.2018). In the current study, the CSPI extracted obtained by alkali-salt based extraction method with alkali: sample ratio (33:1), NaCl (0.15 mol/l), Na2SO3 (0.27%), and time (147.5 min) at pH 11, was evaluated for their functional properties (Kumar et al.2021).

Artemisinin does not contain a chromophore and hence it was difficult to find a sensitive and appropriate analytical method. A UV method was selected which involved post derivatization. This was based on the formation of an alkali salt of artemisinin (Q292) formed by treatment with 0.2% NaOH at 40 °C, however the product was not colored [24]. From visual observation of the extrudates, ArtSD2 was darker in color compared to ArtSD1. This degradation was mirrored in the assays; 83.30% and 78.65% for ArtSD1 and ArtSD2, respectively. However, the modified formulation ArtSD3 (containing citric acid) was found to be 99.76%. As ArtSD3 yielded the highest drug content, this formulation was used for further characterization. All assay results are presented in Table 4.
