The study was designed for phytochemical investigations of ethanolic extract of bark and leaf of Swietenia mahagoni belonging to the family of Meliaceae and evaluation of their biological activities with the special emphasis on analgesic, anti-inflammatory, anti-microbial and cytotoxic screening in different animal model. Phytochemical investigations were done by extensive analysis with high resolution proton NMR spectroscopic data. The ethanol extract of stem bark was partitioned between pet-ether, dichloromethane and methanol fractions. Chromatographic isolation of dichloromethane fraction...

In this ethnopharmacological study, the acetone extract of rhizome (ACR), as well as petroether fraction (PEF), chloroform fraction (CHF), methanol fraction (MEF), and acetone extract of leaf (ACL) were subjected to pharmacological activity test. Phytochemical study revealed the presence of carbohydrates, tannins, flavonoids, proteins, steroids, alkaloids and resins in the crude extract of Kaempferia galanga. In Swiss albino mice, analgesic, neuropharmacological and antidiarrhoeal activity were investigated. The extracts were also evaluated for cytototoxicity and antibacterial activity.

Modern power systems are expected to accommodate more and more renewable energy into the grid to minimize greenhouse gas emission from energy sector. Large scale adoption of solar and wind energy creates instability due to the intermittent nature of these sources. Major problem associated with these sources are harmonics, fluctuation or even unavailability of useful energy during peak demand. Moreover integration of these sources in different phases can cause phase unbalance and power quality (PQ) issues in the network. Energy Storage (ES) can overcome some of these PQ problems by buffering a...
