Abstract:
Background: Boswellia serrata is an important species from the Boswellia genus,
which contains a variety of significant phytoconstituents. Numerous applications of the B. Serrata
have been mentioned in the literature of the Indian ayurvedic system. Researchers reported abundant
pharmacological activities of B. Serrata resins extract. The extract produces synergistic
pharmacological activity due to the presence of the Boswellia acids and their derivatives. Among
all Boswellia acids, 3-O-acetyl-11-keto-β-boswellic acid (AKBA) was found to be more potent.
Traditionally, column chromatography was used for the isolation of AKBA from raw material as
well as extracts. However, the column chromatography method was monotonous and timeconsuming.
Objective: The main goal of the research was to develop a new, simple, rapid, and reproducible
method for the isolation of AKBA from the resin extract of B. Serrata.
Methods: The extraction and isolation of AKBA involved extraction of resins using hydroalcoholic
solution followed by alkali treatment. The alkali solution was further treated with acid to
precipitate the crude AKBA.
Results: The obtained crude AKBA was subjected to the dry column vacuum chromatography to
separate and yield the high purity of the AKBA. The purity of the isolated AKBA was established
by TLC & UHPLC. Spectral characterization of the isolated compound was performed by employing
IR, MS, and NMR.
Conclusion: The proposed method can be used to isolate AKBA from resin extract of B. Serrata.
Some modifications in this method lead to the large-scale production of highly pure AKBA for
various pharmaceutical applications.
