“…From the TPC assay, it was concluded that the polyphenolic concentration in the ethanol and aqueous extracts is highest in those from grass harvested on the ninth day, and amounts to 61.5 and 107.1 mg GAE g −1 fresh sample respectively. Obtained results for TPC were about 50% higher than those reported in the literature for wheat grass 32 …”

Background: Triticum spelta L. (family Poaceae) is an ancient grain, which had been used for nutrition in the past but was eventually substituted, together with other related grains, for bread wheat (Triticum aestivum L.). The main reasons for its substitution are higher yield and economic gain in favor of bread wheat. With the belief that the extract of young spelt grass contains a sufficient amount of key nutrients, which contribute to beneficial effects on human health, research was conducted on 27 samples of young spelt grass extracts. For each sample extracted from young spelt grass cultivated under different conditions (irrigation, lighting, harvest), its nutritional composition, the content of biologically active substances and antioxidant activities were determined, with a comparison of the obtained results. Results:In this two-year study several nutrients, the content of major and trace minerals, antioxidant activity and pigment, and polyphenolic and flavonoid contents were analyzed and how the different growth factors influence them. Young spelt grass extract has a relatively high amount of functional ingredients, such as potassium, phosphorus, manganese, chromium, polyphenols and flavonoids. Chlorophyll a and b and pheophytin were the main pigments in the young spelt grass extract. All of these constituents exhibit antioxidant activity, which is important for a healthy lifestyle and protection against diseases. Conclusion:This extract is a rich source of some major (potassium and phosphorus) and trace (manganese and chromium) elements, pigments, polyphenols and flavonoids. The antioxidant potential of the young spelt grass extract was positively correlated with their phenolic and flavonoid content. Accordingly, this composition of biologically active substances offers various ways of using this extract in the field of nutrition-like dietary supplements.

“…The difference in the growth inhibitory effect between the crude extracts is probably due to the different content of compounds in the different medicinal plant species (Ganga Rao et al, 2012;Missau et al, 2014;Alsultan et al, 2016;Lalitha et al, 2017;Khoo et al, 2018;Pathak et al 2020;Syed et al, 2020;Ove et al, 2021;Wuryatmo et al, 2021). Flavonoids, alkaloids and tannins are frequently reported from the extracts of the nine medicinal plant species (Ganga Rao et al, 2012;Salome et al, 2012;Alsultan et al, 2017;Bhagyasri et al, 2017;Johri and Khan, 2017;Ayirezang et al, 2020;Syed et al, 2020).…”

Aims: Plant diseases caused by pathogens are threatening crop yield. Agrochemicals are used extensively to curb pathogens. Efforts to reduce the usage of agrochemicals are needed for sustainable agriculture. This study was aimed to screen medicinal plants possessing antifungal properties against crop pathogenic fungi. Methodology and results: Sequential extraction using absolute n-hexane, ethyl acetate and methanol was performed on nine selected medicinal plants to obtain crude extract. An antifungal assay using these crude extracts was performed on Fusarium solani, Collectotrichum musae and two isolates of Pyricularia oryzae. The assay showed that medicinal plant species with all three types of crude extract inhibited the growth of all three pathogenic fungal species tested. The inhibitory effects of crude extracts were not only fungal species dependent but also isolate dependent. Conclusion, significance and impact of study: Antifungal effect of nine selected medicinal plant species was observed against the three tested fungal pathogens. These research findings suggest that the selected medicinal plant species may serve as a potential source for the development of new biofungicide products.

“…Thus, methanolic extraction was used in this study on the selected dietary supplements, which showed to be more significantly efficient and more phenolic compounds and other types of antioxidant properties than hexane and acetate extraction (36). In addition, past investigations showed that aqueous extraction could dissolve more polar compounds, for example, phenolic compounds with low and medium molecular weights and medium polarity (37).…”

Introduction: Three selected dietary supplements (DS), barley grass (BG), wheatgrass (WG), and Chlorella vulgaris (CV), are commercially available. However, more information is needed about the antioxidant properties of the three DS and their potential health benefits on adults’ health and well-being. Thus, this study aimed to determine the antioxidant properties and adults’ knowledge, attitudes and practices (KAP) of the three selected DS. Methods: In phase 1, an experimental study was conducted on antioxidant analysis, total phenolic content (TPC) and DPPH radical scavenging activity for the three DS. For phase 2, a cross-sectional survey (n=338) was conducted for the three DS through an online platform where convenience sampling was performed. Results: In phase 1, BG (2.83±0.50mg GAE/g DW) had the highest TPC, followed by WG (2.02±0.20mg GAE/g DW) and CV (1.74±0.65mg GAE/g DW); DPPH radical scavenging activity, BG (198.23±0.15µg/mL) and WG (177.25±0.17µg/mL) had lower IC50 compared to CV (1185.84±0.28µg/mL). Significant differences (p<0.05) were found between IC50 of the three DS and standards, butylated hydroxytoluene (24.51±0.37µg/mL) and quercetin (26.04±0.55µg/mL). While in phase 2, poor knowledge (51.5%), moderate attitude (39.6%), and poor practice (43.2%) levels were observed in most of the participants. Moreover, working adults reported higher scores in knowledge (3.70±1.51) compared to students (3.33±1.63, p=0.037). Males had higher scores (29.27±2.42) in attitude compared to females (28.49±2.68, p=0.030). Besides, participants who were single and completed tertiary education with 4-6 years of working experience showed better practice scores. The overall knowledge (r=0.134, p=0.013) and attitude (r=0.273, p<0.001) scores correlated significantly with practice scores. Conclusion: Participants’ poor knowledge, moderate attitude, and inadequate practice in phase 2 caution against over-reliance on supplements, emphasizing the importance of an active lifestyle and balanced diet for optimal health and longevity.
