Diospyros lotus L. possesses different therapeutic activities such as antioxidant, anti-proliferative, anti-microbial and sedative. However, no studies on the sedative-hypnotic activity of 7-methyljuglone are reported. In the present study, we have evaluated in vivo the anxiolytic-hypnotic like
This study was designed to evaluate the antihyperalgesic effect of crude extract of Diospyros lotus followed by the isolation and characterisation of 7-methyljuglone in acetic acid and formalin tests. The pretreatment of crude extract evoked dose-dependent inhibition of noxious stimulation with
A preparative overpressure layer chromatography (OPLC) method was successfully used for the separation of two new natural compounds, 4-hydroxy-5,6-dimethoxynaphthalene-2-carbaldehyde (1) and 12,13-didehydro-20,29-dihydrobetulin (2) together with nine known compounds, including 7-methyljuglone (3),
Root bark of West African tree Diospyros batocana Hiern, Ebenaceae, was examined. On the basis of chromatographic and spectral analysis it was shown to contain the naphtaquinones 7-methyljuglone, 2-methylnaphthazarin, biramentaceone, rotundiquinone, mamegakinone, diospyrin, diosquinone, isodiospyrin
The aim of this study was to explore the extract/fractions and compounds of Diospyros lotus against various Gram-positive and Gram-negative bacteria strain. The results showed marked susceptibility of extract and its fractions against test pathogens. Among them, chloroform fraction was most dominant
Diospyros lotus L. is traditionally used in various diseases including pain and sleep disorders. The pain and inflammation are the common problems, which are treated with various synthetic analgesic drugs, and associated the side effects. The natural products have gained significant importance over
The twigs of Diospyros lycioides, a plant commonly known as "muthala", are frequently used as chewing sticks for the cleaning of teeth by rural and urban people in Namibia. Preliminary studies showed that a methanol extract of D. lycioides inhibited growth of selected oral pathogens. Subsequent
Bioactivity-directed fractionation of extracts of two Diospyros maritima bark samples from Indonesia,one collected at sea level in a beach forest in Java and the other collected at a slight elevation away from the sea shore on the island of Lombok, yielded a diverse set of secondary metabolites. The
From the chloroform extract of the fresh fruits of Diospyros maritima BLUME (Ebenaceae), five new naphthoquinone derivatives, 2,7'-dimethyl-2',3-bijuglone (27), 2,7'-dimethyl-3,3'-bijuglone (28), 2,7'-dimethyl-6,8'-bijuglone (29), 7,7'-dimethyl-3,3'-ethylidenebijuglone (30), and
The molluscicidal and fungicidal properties of DIOSPYROS USAMBARENSIS root bark have been attributed to the naphthoquinone 7-methyljuglone. In addition, the dimeric naphthoquinones isodiospyrin and mamegakinone and 2 artefacts, 2-methoxy- and 3-methoxy-7-methyljuglone have been isolated.
