TL;DR: The leaves extracts of Corchorus olitorius, the family Malvaceae, are commonly called khudra, the plant extensively used in Sudanese traditional medicine as mentioned in this paper.
Abstract: The leaves extracts of Corchorus olitorius, the family Malvaceae, are commonly called khudra, the plant extensively used in Sudanese traditional medicine. The Sudanese varieties are one of the best in the market, which prompted investigation of leaves extracts. Some chemical analyses of the leaves have been done such as determination of ash content and trace elements (Ca, Fe, Mg, and Na) by atomic absorption spectrometry. The 96% ethanolic, Ethyl acetate and chloroform extracts exhibited significant antimicrobial activity and highlighted the biological monitoring of activity in order to isolate the active metabolites from the ethanolic extract of the leaves. The presence of sterols and triterpenes, carotenoids, coumarins, alkaloids, saponins, tannins, flavonoid and carbohydrates was confirmed by phytochemical screening of the diethyl ether, methanolic and aqueous extracts of the leaves. The extracts were screened in different solvent systems by thin layer chromatography. The methanolic, Ethyl acetate extract exhibited significant antioxidant activity. From the above-mentioned extract we prepare cream and ointment as antibacterial and antifungal dosage forms.

TL;DR: This is the first report of PLRV naturally occurring on jute (C. olitorius), a important bast fiber crop that is mainly grown in the Southeast Asian countries like India, Bangladesh, Nepal, China, Indonesia, Thailand, Myanmar, and a few South American countries.
Abstract: Jute (Corchorus olitorius L.) is an important bast fiber crop that is mainly grown in the Southeast Asian countries like India, Bangladesh, Nepal, China, Indonesia, Thailand, Myanmar, and a few South American countries. In June 2013, symptoms suggestive of a viral disease were noticed on jute (cv. JRO524) in an experimental field of the CRIJAF research farm, Barrackpore, India, and the incidence of the disease was less than 2%. The infected plants showed stunted growth and short height. Mostly the upper leaves elongated with curling and coiling of lamina. Puckering and shoe string effect were also noticed. Petioles and stipules of the affected leaves were exceptionally longer. Although initially the incidence was low, it may spread to larger areas in subsequent years. Because the jute fiber is extracted from the stem, stunted growth and short height would badly affect the fiber yield and quality. Ten symptomatic and ten asymptomatic healthy looking samples were collected from the field. Corchorus golden m...

TL;DR: In this article, the effects of hot air drying variables including: air temperature (50, 60 and 70 oC), air velocity (0.2, 0.4 and 0.6 m/ s) and trays load (125, 500 g/ 0.22 m2) on the antioxidant capacity and some phytochemicals content of Jew's mallow leaves were studied.
Abstract: Jew's mallow (Corchorus olitarius L.) is an important vegetable in Egypt. Fresh or dried Jew's mallow leaveshave a wide use and is great demand for domestic as well as export markets. The effects of hot air drying variablesincluding: air temperature (50, 60 and 70 oC), air velocity (0.2, 0.4 and 0.6 m/ s) and trays load (125 – 500 g/ 0.22 m2)on the antioxidant capacity and some phytochemicals content of Jew's mallow leaves were studied. The fresh Jew'smallow leaves exhibited high antioxidant activity (52.29% and 139.55 μmol trolox/ g dry weight, measured by DPPHand ABTS assays, respectively). The leaves had high contents of chlorophyll a and b (649.4 and 317.4 mg/ 100 g), totalphenolics (16.54 mg GAE/ g) and total flavonoids (117.88 mg quercetin equivalent/ g). Drying process resulted indrastic decreases in all studied properties except the β-carotene content. Antioxidant activity and phytochemicalscompounds contents decreased as air drying temperature and velocity decreased, relating to long drying times. Dryingat 60 oC and air velocity 0.6 m/ s had the lowest negative effect on the leaves antioxidant activity. Leaves dried at thehighest trays load (500 g/ 0.22 m2) also, showed the highest antioxidant activity and phytochemicals contents.

TL;DR: The results suggest that the ethanolic extract of C. olitorius leaf possesses antihyperglycemic property with no major side effect hence it could be considered safe for the management of diabetes.
Abstract: Diabetes is a major metabolic disease of global concern. Ethanolic extract of Corchorus olitorius leaf was investigated for antidiabetic activity in alloxan-induced diabetic rats. A total of thirty-six albino rats (Rattus norvegicus) with body weight 150.50 10.50 g were randomly selected into six groups (A–F). Group A animals were non-diabetic and received 0.5 mL distilled water, groups B, C, D, E and F were made diabetic by administration of alloxan monohydrate (150 mg/kg, body weight i.p). Group B was diabetic untreated, group C was diabetic and treated with glibenclamide, while groups D, E and F received the ethanolic extract of C. olitorius leaf at a dose of 200 mg/kg, 400 mg/kg and 800 mg/kg body weight respectively. Phytochemical screening showed the presence of flavonoids, tannins, saponins, phlobatannin anthraquinones, phenol and cardiac glycoside and saponin. The blood glucose of the alloxanized rats after 72 hours which ranged from 17.30–25.33 mmol/L were significantly (p < 0.05) and progressively reduced in treated groups which compared favorably with the standard drug group. The significantly (p < 0.05) elevated levels of serum and liver bilirubin (direct and total), transaminases (AST and ALT), alkaline phosphatase, urea, creatinine, total cholesterol, triglyceride, LDL-C, as well as reduced levels of total protein, globulin, albumin and HDL-C in the diabetic untreated rats were normalized upon treatment with ethanolic extract of C. olitorius leaf. These results suggest that the ethanolic extract of C. olitorius leaf possesses antihyperglycemic property with no major side effect hence it could be considered safe for the management of diabetes.

TL;DR: The molecular phylogenetic relationships among the important members of these two genera Corchorus L. and Hibiscus L. are described to be related through maternal inheritance as well as to know their relative dispersal throughout the world.
Abstract: Members of the genera Corchorus L. and Hibiscus L. are excellent sources of natural fibers and becoming much important in recent times due to an increasing concern to make the world greener. The aim of this study has been to describe the molecular phylogenetic relationships among the important members of these two genera as well as to know their relative dispersal throughout the world. Monophyly of Corchorus L. is evident from our study, whereas paraphyletic occurrences have been identified in case of Hibiscus L. Although C. olitorius is assumed to be originated from Africa and C. capsularis from Indian subcontinent, our study found both to be related through maternal inheritance. This prompted us to put forward a hypothesis with archeological support to explain the dispersal routes of migration of these two Corchorus species. Similar migratory occurrences may also be true for Hibiscus L.
