Jute mallow is a traditional leaf vegetable that is an important part of daily diet for the majority of people in rural areas in sub-Saharan Africa. Here we employed quantitative and qualitative phenotypic traits to assess the morphological diversity of 90 accessions using univariate and multivariate analyses. Field experiments were conducted for two seasons to identify accessions suitable for leaf yield. The accessions were significantly variable in all traits. Highest variability among accessions was found in harvest index, biomass yield, and weight of 1000 seeds. The traits that significantly correlated with biomass yield include plant height ( = 0.448), petiole length ( = 0.237), primary branches ( = 0.319), and number of leaves per plant ( = 0.333). Principal component analysis showed that the first five PCs with eigenvalues ≥1 explained 72.9% of the total variability in the accessions. Pods per plant, primary branches, secondary branches, and number of leaves per plant accounted for highest variability in PC1. Cluster analysis grouped the accessions into five major clusters mainly based on their origin. Thus, the collection displayed high variation in morphological traits, particularly those related to leaf yield. These accessions are therefore useful in breeding for the improvement of the crop and germplasm management.

“…It is commonly grown in Africa and the Middle East, especially in Egypt, where it is known as Molokhia (Ilhan, Savaroğlu, & Çolak, ). The leaves are widely used in cuisines of many countries due to their mucilaginous texture (Loumerem & Alercia, ). Co extract was shown to have a high phenolic content with potent antioxidant and anti‐inflammatory activities (Handoussa et al., ) with beneficial effects in a variety of medical conditions, such as microbial infections, obesity, diabetes, and cancer.…”

Dietary phenolics are known for their potent antioxidant and anti-inflammatory activities, making them promising candidates for protection against neuroinflammation and neurodegeneration. Hydroalcohol extract of Egyptian species of Corchorus olitorius L. (Co) leaves was investigated for its neuroprotective effects in a lipopolysaccharide-induced neuroinflammatory mouse model. Twenty five metabolites were characterized from the bioactive extract using highperformance liquid chromatography HPLC/PDA/HRESI/MS n , revealing 1,5-dicaffeoylquinic acid (Co11) as one of the major constituents (5.7%), which was isolated and its identity was confirmed by spectral data as first report. Co significantly protected microglia against H 2 O 2 -induced cytotoxicity and immunohistochemistry showed reduced expression of the astrocytic marker, glial fibrillary acidic protein, and the inflammatory marker, cyclooxygenase-2. These findings correlated with significant improvement of cognitive functions and reduction of LPS-induced neurodegeneration in Co-treated mice as revealed by histopathology. The current study shows promising effects of Co in limiting neurodegeneration and cognitive impairment caused by neuroinflammation and glial cell activation.Practical Application: Information presented here shed light on the promising effects of Corchorus olitorius (Co) for the modulation of neuroinflammatory pathways improving the neuroinflammation-related neurodegeneration and cognitive decline. This makes Co a promising candidate as a nutraceutical supplement to be used against neuroinflammation-related disorders.

Objective: The aim of this study was to investigate chemical constituents of leaves and seeds of Corchorus olitorius since no phytochemical investigation had been done previously in Iraq.Methods: Leaves and seeds of C. olitorius were defatted by maceration in hexane for 24 h. The defatted plant materials were extracted using Soxhlet apparatus, the aqueous methanol 85% as a solvent extraction for 24 h, and fractionated by petroleum ether, chloroform, ethyl acetate, and n-butanol. The ethyl acetate, n-butanol, and n-butanol after hydrolysis fractions for each part (leaves and seeds) were analyzed by high-performance liquid chromatography (HPLC) and high-performance thin-layer chromatography (HPTLC) for its phenolic acid and flavonoid contents. The petroleum ether fraction from the leaves was analyzed using Gas chromatography/mass spectrometer (GC/MS). Flavonoids and phenolic acid derivative were isolated from the ethyl acetate of leaf fraction and n-butanol after hydrolysis fraction of the seeds and identified by mass spectrometry, infrared, HPLC, and HPTLC.Results: The different chromatographic and spectroscopic results revealed the presence of luteolin, quercetin, astragalin, isoquercetin, catechins, and 3,5-dicaffeoylquinic acid (3,5-DCQA) in both leaves and seeds of C. olitorius and also 17-octadecynoic acid, 9-octadecanoic acid (oleic acid), hexadecenoic acid (palmitic acid), 9,12-octadecanoic acid (linoleic acid), octadecadien-1-ol (β-sitosterol), and α-tocopherol (Vitamin E) in the petroleum ether fraction of C. olitorius leaves.Conclusion: The results of the current study proved the presence of 3,5-DCQA, astragalin, and isoquercetin in the ethyl acetate fraction of C. olitorius leaves and catechin in the n-butanol after hydrolysis fraction of C. olitorius seeds.
