Background   Boswellia serrata , also known as Indian frankincense is a commercially important medicinal plant which has been used for hundreds of years as an Ayurvedic medicine for the attempted treatment of arthritis. It contains naturally occurring triterpenoic acids, called as boswellic acids (BA’s).    Results  A highly reproducible High performance liquid chromatography-ultraviolet diode array detection (HPLC-UV-DAD) method was developed for the simultaneous determination and quantitative analysis of eight major triterpenoic acids in  Boswellia serrata  gum resin obtained by different extraction techniques. All the calibration curves exhibited good linear regression (R 2  > 0.997) within the test ranges. The established method showed good precision and overall recoveries of the boswellic acids.    Conclusions  The eight triterpenoic acids coded as BS-1 (11-keto-beta-boswellic acid), BS-2 (3- O -acetyl-11-keto-beta-boswellic acid), BS-3 (3-keto tirucallic acid), BS-4 (3- O -acetyl-alpha-tirucallic acid), BS-5 (3- O -acetyl-beta-tirucallic acid), BS-6 (alpha-boswellic acid), BS-7 (beta-boswellic acid) and BS-8 (3- O -acetyl-beta-boswellic acid) were isolated from the processed gum resin of  Boswellia serrata  by column chromatography. The proposed HPLC method is simple, reliable and has been very useful for the qualitative as well as quantitative analysis of boswellic acids in the gum resin of  Boswellia serrata . The proposed method allows to quantify boswellic acids in appreciable amounts by HPLC-UV (DAD) method in the extracts and the available marketed formulations.
