Abstract: Extracts of Matricaria aurea flowers are shown to exhibit anticorrosive activity when used with mild steel in acidic media. A process is shown for obtaining such anticorrosive extracts from the flowers of M. aurea. In particular, certain methanolic, aqueous methanolic and water extracts, as well as ethyl acetate and n-butanol fractions, of M. aurea flowers are shown to demonstrate particular anticorrosive activity when used with mild steel in acidic media. An isolated flavonoid compound from M. aurea flowers, designated as apigenin-7-O-?-D-glucoside, is particularly useful for anticorrosive activity when used with mild steel in acidic media.

Abstract: The biosynthesized magnetic metal nanoparticles for oil spill remediation are magnetic nanoparticles capped with an extract of Anthemis pseudocotula. The magnetic nanoparticles are formed by co-precipitation of ferric chloride hexahydrate and ferrous chloride tetrahydrate in an ethanol solution of the extract with the dropwise addition of ammonium hydroxide to raise the pH to between 8 and 11. The extract may be an extract of the aerial parts of Anthemis pseudocotula in a low polar extraction solvent, such as an n-alkane solvent or mono-di-, or trichloromethane. The extract is hydrophobic, improving dispersion of the magnetic nanoparticles in oil spills in seawater, resulting in 90% removal of oil for a 1:10 ratio of nanoparticles:oil by weight.

Abstract: The present invention provides novel loganin analogues and a process for the preparation thereof. The present invention further provides the use of Iridoid glycoside loganin isolated from the fruit pulp of Strychnos nux-vomica and its bioactive semi-synthetic analogues against various human cancer cell lines grown in-vitro.

Abstract: The present invention provides an improved process for the isolation of oleane compounds from the bark of Terminalia arjuna (Roxb.). More particularly, the present invention relates to an improved process for the isolation of arjunic acid and its derivates from the bark of Terminalia arjuna (Roxb.). The present invention further provides the identification of arjunic acid [1] and its derivatives as anticancer agent useful in the treatment of various types of cancer in humans.
