Isolation and biological evaluation of steroid from stem of Costus igneus
Isolation of the ethanol extract of the plant Costus igneus has been done. The single compound was isolted in a particular fraction (206-218) were characterized by UV, IR ,HNMR C NMR, Dept 135, ESI-MS spectroscopy. The antimicrobial activity of the isolated compound was evaluated, on Staphylococcus aureus, Eschericia coli and Candida albicans. The present investigation deals with the isolated c...
متن کاملIsolation, Identification, Whole-Genome Sequencing, and Annotation of Four Bacillus Species, B. anthracis RIT375, B. circulans RIT379, B. altitudinis RIT380, and B. megaterium RIT381, from Internal Stem Tissue of the Insulin Plant Costus igneus
Here, we report the isolation, identification, whole-genome sequencing, and annotation of four Bacillus species from internal stem tissue of the insulin plant Costus igneus, grown in Puerto Rico. The plant is of medicinal importance, as extracts from its leaves have been shown to lower blood sugar levels of hyperglycemic rats.
متن کاملChemical constituents of Rourea doniana
The chromatography fractionation of the hexane, chloroform and ethyl acetate extracts from the leaves and stems of Rourea doniana Baker, Connaraceae, resulted in the isolation of five triterpenes (lupeol, lupenone, α-amyrenone, β-amyrenone, and taraxerol), a flavonol (7,4’-dimethylkaempferol), a coumarin (scopoletin) and four phytosteroids (β-sitosterol, stigmasterol, β-sitosteryl-3-Oβ-D-glucop...
متن کاملStudies On Antibacterial Activity Of Root Extract Of Costus Igneus
Antibacterial activity of Costus igneus was conducted. The plant C. igneus was well known for its anti-diabetic property. Traditionally the plant was used to treat fever, rash, asthma and intestinal worms. Two growth regulator IAA (Indole 3-acetic acid) and IBA (Indole butyric acid) in combinations were applied to MS medium for direct root induction. MS medium supplemented with 0.5mg/ml IBA, in...
متن کاملEvaluation of Antidiabetic activity of Costus igneus(L) leaves on STZ induced diabetic rats
The aim of this research was to investigate antidiabetic activity of Costus igneus (also known as insulin plant) leaves extracts in streptozotocin induced diabetic albino rats. A comparison was made between the action of Costus igneus extract and a known antidiabetic drug glibenclamide (5mg/kg body wt.). An oral glucose tolerance test (OGTT) was also performed in experimental diabetic rats. Eth...
