TL;DR: Results of the present study revealed that both the processed extracts showed a significant anticonvulsive property by altering the level of catecholamines and brain amino acids in mice.
Abstract: The methanolic extract of both Cuscuta reflexa stem and Corchorus olitorius seed showed marked protection against convulsion induced by chemoconvulsive agents in mice. The catecholamines contained were significantly increased in the processed extract treated mice. The amount of GABA, which is most likely to be involved in seizure activity, was increased significantly in mice brain after a six week treatment. Results of the present study revealed that both the processed extracts showed a significant anticonvulsive property by altering the level of catecholamines and brain amino acids in mice.

TL;DR: In this paper, the effects of different seed treatment methods and durations of exposure on germination of wild okra (Corchorus olitorius), a traditional leafy vegetable consumed in many parts of Africa, were investigated.
Abstract: The effects of different seed treatment methods and durations of exposure on germination of wild okra (Corchorus olitorius), a traditional leafy vegetable consumed in many parts of Africa, were investigated. Seeds were exposed to seven treatments (hot water at 80 °C, hot water at 100 °C, dry heat at 80 °C, dry heat at 100 °C, concentrated sulphuric acid, 10% hydrogen peroxide and water at room temperature) for periods of up to 30 minutes. Exposure for five to 15 minutes in hot water at 80 °C was the most effective treatment for enhancing germination (>90%), followed by five minutes in hot water at 100 °C (80%) and 30 minutes in sulphuric acid (57%). Other treatments were less effective. Soaking seeds in hot water at approximately 80 °C for about 10 minutes can be recommended, therefore, to farmers as a simple, cheap and very effective way of germinating wild okra.

TL;DR: High level of substrates and low level of enzymes indicate the inhibition of steroidogenesis in treated mice and may be due to the presence of flavonoids.
Abstract: Methanolic extract (ME) of both C. reflexa stem and C. olitorius seed arrested the normal oestrus cycle of adult female mouse and significantly decreased the weight of ovaries and uterus. The cholesterol and ascorbic acid contents in ovaries were significantly increased in the treated mice. Two key enzymes, delta5-3beta-hydroxysteroid dehydrogenase and glucose-6-phosphate dehydrogenase, were decreased significantly in ME of both C. reflexa stem and C. olitorius seed after 17 days of treatment. High level of substrates and low level of enzymes indicate the inhibition of steroidogenesis in treated mice and may be due to the presence of flavonoids.

TL;DR: It is assumed that the probable cause of delayed maturation in ME of Cuscuta reflexa stem and Corchorus olitorius seed treated mice is due to the suppressed ovarian steroidogenesis.

TL;DR: In this paper, the level of heavy metals in two varieties of vegetables harvested during the dry and wet seasons from seven different locations in Ilorin, Nigeria, were determined and the correlation between the levels of metals in the vegetables and the irrigation water was also studied.
Abstract: The level of heavy metals in two varieties of vegetables harvested during the dry and wet seasons from seven different locations in Ilorin, Nigeria, were determined. The correlation between the level of metals in the vegetables and the irrigation water was also studied. Vegetables harvested during the dry season were found to contain higher level of toxic metals. Low water quality, accumulation of particulate after rainless period and nearness of some vegetable gardens to major and well travelled roads appeared to be the major contributory factors. Amaranthus hybridus seemed to have higher metal accumulation capacity compared to Corchorus olitorius mannii . KEY WORDS: Trace elements, Heavy metals, Vegetables, Irrigation water, Water quality, Metal ccumulation capacity, Amaranthus hybridus , Corchorus olitorius mannii Bull. Chem. Soc. Ethiop. 2003 , 17(1), 107-112.

TL;DR: The antifertility nature of methanol extract of C. reflexa stem and C. olitorius seed is established and the increased rate of enzymatic activity might be associated with elevated level of progesterone induced by these methanolic extracts.
Abstract: The effects of multiple intraperitoneal doses of methanolic extract of Cuscuta reflexa Roxb. stem and Corchorus olitorius Linn. seed on the activity of carbonic anhydrase in the uterus of micewere studied. These methanolic extracts caused a significant increase in the carbonic anhydrase activity in the uterus of mice. The increased rate of enzymatic activity might be associated with elevated level of progesterone induced by these methanolic extracts. This further establishes the antifertility nature of methanol extract of C. reflexa stem and C. olitorius seed.

TL;DR: In this paper, a cosmetic composition containing an extract of Corchorus olitorius belonging to Tiliaceae having an effect on smoothly supplying oxygen and nutrients to cells by discharging lipid peroxide while scavenging toxic oxygen species known as an aging causing material is provided.
Abstract: PURPOSE: A cosmetic composition containing an extract of Corchorus olitorius belonging to Tiliaceae having an effect on smoothly supplying oxygen and nutrients to cells by discharging lipid peroxide while scavenging toxic oxygen species known as an aging causing material is provided. Therefore, the cosmetic composition has great safety to the skin, product stability and usability as well as skin aging-retarding effect. CONSTITUTION: The cosmetic composition contains 0.01 to 10.0% by weight of an extract of Corchorus olitorius, together with conventional cosmetic composition. The cosmetic composition is cream, skin lotion, astringent, milk lotion, foundation, soap, shampoo or the like. For an example, 300g Corchorus olitorius leaf powder is soaked in 3,000ml mixed liquid of purified water and ethanol in a ratio of 1:2 at 25deg.C for 7 days, extracted and then filtered to produce 44g concentrate.

TL;DR: A field experiment with jute (Corchorus sp.) varieties was conducted during the rainy season of 1997 and 1998 at Raigarh, with 4 sowing dates and 2 fertility levels as discussed by the authors.
Abstract: A field experiment with jute (Corchorus sp.) varieties was conducted during the rainy season of 1997 and 1998 at Raigarh, with 4 sowing dates and 2 fertility levels. Significantly higher values of growth, yield attributes and fibre yield were recorded with earlier sowing than delayed sowing. Maximum fibre yield of 2, 412 kg/ha was obtained when the crop was sown on 10 June, which drastically decreased with delay in sowing on 20, 30 June and 10 July (1, 995, 1, 492 and 1, 240 kg/ha respectively). Tossa jute (Corchorus olitorius L.) variety ‘JRO 524’ (1, 844 kg/ha) gave higher fibre yield than to white jute (C. capsularis L.) ‘JRC 212’ (1, 726 kg/ha). The white jute ‘JRC 212’ gave higher fibre yield when sown on 10 June with fertility level of 60: 40: 30 kg N: P2O5: K2O/ha, whereas the sowing of ‘JRO 524’ can be extended up to 20 June with fertility level of 60:45:45 kg N: P2O5: K2O/ha.
