Abstract: The present invention relates to a facile, highly efficient and economical process for the preparation of optically active N-benzyl-3-hydroxypyrrolidine in high yield from a naturally occurring alkaloid vasicine. The natural alkaloid vasicine is used as a precursor of (S)—N-benzyl-3-hydroxypyrrolidine and (R)—N-benzyl-3-hydroxypyrrolidines which can easily be sourced from the medicinal plant Adatoda vasica by the method known in the art and transformed to optical isomers (R) and (S)—N-benzyl-3-hydroxypyrrolidine by the method described in the present invention.

Abstract: The present invention relates to use of compounds of general formula 1 for anticancerous activity, wherein the said compound being derived semi-synthetically from natural triterpenoic acids known as boswellic acids by the induction of apoptosis thereof cytotoxicity and anti-cancer activity displayed by semi-synthetic analogues of natural triterpenes, known as Boswellic acids. These compounds may be used for the treatment of cancer, alone or in combination with pharmaceutically acceptable or other carriers, displaying cytotoxicity and anti-cancer activity for colon, prostrate, liver, breast, central nervous system (CNS), leukemia and malignancy of other tissues, including ascites and solid tumors. The cancer cell death is mediated by induction of apoptosis and inhibition of cell proliferation at specific doses.

Abstract: The present invention relates to a process for the synthesis of racemic nerol oxide i.e. 3,6-dihydro-4-methyl-2-[2-methyl-1-propenyl)-2H-pyran from monoterpene alcohol nerol i.e. cis-3,7-dimethylocta-2,6-diene-1-ol.

Abstract: The present invention relates to anti-microbial activity of the essential oil of Cymbopogon flexuosus (Nees ex Steud) Wats and the process of isolation of novel sesquiterpene compound which is mainly responsible for the strong anti-microbial/anti-bacterial activity. The present invention particularly relates to anti-bacterial activity of the essential oil and a pure isolate identified as (+)-1-bisabolone of formula 1 against gram positive bacteria from a strain of a grass identified as Cymbopogon flexuosus.

Abstract: The present invention relates to a process for the systhesis of optically enriched dextro- and laevo-rotatory isomers of rose oxide from racemic citronellol. The invention particularly relates to the preparation of optically enriched (−)-(2 S, 4 R)-rose oxide and its isomer (+)-(2 R, 4 S)-rose oxide torn racemic citronellol.

Abstract: The present invention relates to a process for the systhesis of optically enriched dextro- and laevo-rotatory isomers of rose oxide from racemic citronellol. The invention particularly relates to the preparation of optically enriched (−)-(2 S, 4 R)-rose oxide and its isomer (+)-(2 R, 4 S)-rose oxide torn racemic citronellol.
