A series of homoisoflavonoids and chalcones, isolated from the endemic tropical plant Dracaena cinnabari Balf. (Agavaceae), were tested for their potential to inhibit cytochrome P4501A (CYP1A) enzymes and Fe-enhanced in vitro peroxidation of microsomal lipids in C57B1/6 mouse liver. The effects of
BACKGROUND
Food preservation is basically done to preserve the natural characteristics and appearance of the food and to increase the shelf life of food. Food preservatives in use are natural, chemical and artificial. Keeping in mind the adverse effects of synthetic food preservatives, there is a
Endogenous and exogenous antioxidants are used to neutralise free radicals and protect the body from free radicals by maintaining the redox balance. The antioxidant properties of Dracaena sanderiana leaves were evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, and the total phenolic
The antioxidant activities of the petroleum ether, ethyl acetate, n-BuOH and water extract fractions from Dracaena cambodiana Pierre ex Gagnep were evaluated in this study. The ethyl acetate fraction contained the highest amount of total phenolics and total flavonoids, and showed the greatest DPPH˙,
Dracaena cinnabari Balf. f. (Dracaenaceae) is an important plant endemic to Soqotra Island, Yemen. Dragon's blood (Dam Alakhwin) is the resin that exudes from the plant stem. The ethnobotanical survey was carried out by semi-structured questionnaires and open interviews to document the
In the present study, the antioxidant activity of successive leaf extracts of Dracaena reflexa was investigated using the scavenging activity on 1,1-diphenyl-2-picrylhydrazyl and reducing power by ferric reducing antioxidant power assay. Methanol extract was found potent in both the assays. IC50
OBJECTIVE
To investigate the effects of Dracaena arborea (D. arborea) on the sexual behavior parameters in experienced type-1 diabetic rats.
METHODS
Aqueous and ethanol (100 and 500 mg/kg respectively) extracts of dried root barks of D. arborea, sildenafil citrate (1.44 mg/kg),
Reproductive dysfunction is one of the most prevalent diabetes complications. Draceana arborea is known to enhance sexual function in diabetic rats, but the underlying mechanisms have not been thoroughly elucidated. This study examined the effects of D. arborea on some reproductive complications of
OBJECTIVE
To screen micro-organisms for inducing the production of dragon's blood, which is normally produced by stem xylem and by leaf of Dracaena cochinchinensis, and to evaluate the product by comparing with the standard.
RESULTS
Thirty microbial strains were isolated from D. cochinchinensis
Dragon's blood is a traditional medicine widely used in the world from ancient times. However, little is known about its formation mechanism. This work aimed to gain some insights into its formation mechanism and to control its production. The results demonstrate that wounding plus causal fungal
The etiology of inflammatory bowel disease (IBD) is not yet known, but many factors such as defects in the immune system, oxidative stress, microbial content in the gastrointestinal tract, nuclear factor (NF)-κB, nitric oxide (NO), cyclooxygenase-2 (Cox-2), and leukotriene B4 (LB4) are thought to
The genera Dracaena and Sansevieria (Asparagaceae, Nolinoideae) are still poorly resolved phylogenetically. Plants of these genera are commonly distributed in Africa, China, Southeast Asia, and America. Most of them are cultivated for ornamental and medicinal purposes and are used in
