Chemotaxonomic investigations on resins of the frankincense species Boswellia papyrifera, Boswellia serrata and Boswellia sacra, respectively, Boswellia carterii : a qualitative and quantitative approach by chromatographic and spectroscopic methodology
Abstract
Extracts from the resin exudates of the frankincense tree again returned into the focus of pharmacological research within the last 20 years. So far, several research groups reported on promising anti-inflammatory, anti-microbial and even anti-tumour effects (in vitro and in vivo). The Boswellic acids are regarded as one of the most potent active agents thereof. However, the resins still contain innumerable amounts of terpenoid compounds. Their interactions, when administered as an extract, are not really understood hitherto. In addition, the information given in literature as to which molecular entity refers to which species has not been clearly verified in several publications. Thus, this work reports on qualitative and quantitative analytical methods (LC, GC, TLC, MS and NMR), which enable the unequivocal identification of the common incense species Boswellia papyrifera (Eritrea, Ethiopia), Boswellia serrata (India) and Boswellia sacra (Oman, Yemen), respectively, Boswellia carterii (Somalia). Based on these results, a general, though not yet empirically verified, hypothesis on the biosynthetic routes has been postulated. Besides, a partial-synthetic method for the enrichment of one compound (Incensole acetate) was developed. In cooperation with Prof. Werz (Jena) a few of the isolated compounds were tested to evaluate their pharmacological potential. The results delivered evidence on possible synergistic effects which were partly based on decompositions of single molecules…

“However, comparison of their mass spectra with those of isolated incensol [47] and serratol [48] reveals that compound 127 was correctly identified as incensol but that compound 128 corresponds to serratol, a diterpenoid common to Boswellia species, particularly B. sacra, B. carterii and B. serrata [46], [48], [49].”

“The ratio of 3-O-acetyl-11-keto-β-boswellic acid to 11-keto-β-boswellic acid has been proposed as a further species-specific criterium [45], [46].”

“However, many identification criteria that apply for fresh frankincense, such as the ratio of 3-O-acetyl-11-keto-β-boswellic acid to 11-keto-β-boswellic acid and the percentages of lupane or tirucallane compounds [45], [46], cannot be used for the ancient residues.”

“Inter-species variation in chemical composition was verified by analyzing commercial resins of B. carterii, B. papyrifera, B. sacra and B. serrata. Our results are summarized in Table 2 and correspond well to published data [20], [26], [46].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
