Antimicrobial activity of Callistemon citrinus and Callistemon salignus methanolic extracts

Chemical composition and antibacterial activity of the essential oils of Callistemon citrinus and Callistemon viminalis from South Africa.

The chemical composition and the antibacterial activity of the essential oils obtained by hydrodistillation from the leaves of Callistemon citrinus and Callistemon viminalis were analyzed by GC and GC/MS. Twenty-four and twelve components were identified for C. citrinus and C. viminalis, representing 92.0% and 98.3% of the total oils. The major components of C. citrinus and C. viminalis were 1,...

Acute toxicity, brine shrimp cytotoxicity and relaxant activity of fruits of callistemon citrinus curtis

BACKGROUND Callistemon citrinus Curtis belongs to family Myrtaceae that has a great medicinal importance. In our previous work, fruits of Callistemon citrinus were reported to have relaxant (antispasmodic) activity. The current work describes the screening of fractions of the crude methanol extract for tracing spasmolytic constituents so that it shall help us for isolation of bioactive compound...

Antibacterial Properties of Alkaloid Extracts from Callistemon citrinus and Vernonia adoensis against Staphylococcus aureus and Pseudomonas aeruginosa

The development of new antibiotics from new chemical entities is becoming more and more expensive, time-consuming, and compounded by emerging strains that are drug resistant. Alkaloids are plant secondary metabolites which have been shown to have potent pharmacological activities. The effect of alkaloids from Callistemon citrinus and Vernonia adoensis leaves on bacterial growth and efflux pump ...

Pharmacognostic study and anti-inflammatory activity of Callistemon lanceolatus leaf.

OBJECTIVE To study detail pharmacognosy and anti-inflammatory activity of Callistemon lanceolatus (C. lanceolatus) leaf. METHODS Leaf sample was studied by organoleptic, macroscopical, microscopical, phytochemical and other WHO recommended methods for standardizations. The methanolic leaf extract of the plant was also screened for anti-inflammatory activity on carrageenan-induced paw edema in...
