Trace Elements and Proximate Analysis of <i>Boswellia dalzielii</i> Stem Bark

Abstract

Boswellia dalzielii (B. dalzielii) Hutch is a tree plant of the Burseraceae family found in Savannah woodlands. The decoction of stem bark has been reported to be useful in treating gastrointestinal diseases, rheumatism, septic sores, and sexual ailments. Additionally, it has demonstrated antifungal, antibacterial, and anti-inflammatory properties. The research was undertaken to evaluate the trace element contents and nutritional contents of the stem bark of B. dalzielii using standard methods of the Association of Official Analytical Chemists (AOAC). The elemental analysis showed the presence of: Zn (5.82±0.021 mg/kg), Cu (4.22±0.017 mg/kg), Mn (31.24±0.114 mg/kg), and Fe (9.12±0.318 mg/kg), Se (3.13m±0.223 g/kg) Cr (0.0026±0.211 mg/kg), Co (0.00 mg/kg), Mo (0.0016±0.001 mg/kg), Cd (0.0037±0.117 mg/kg), Ni (0.0016±0.324 mg/kg), and I (4.15±0.214 mg/kg). While the proximate analysis revealed the presence of the following: ash content (5.97±0.315%), moisture (6.22±0.115%), protein (18.52±0.018%), fiber 16.2±0.215%), crude fat (6.02±0.002%), and carbohydrate (31.73±0.224%). Trace elements have well-characterized physiological functions within the body. They regulate biological processes, thereby stabilizing the structures of cells when they are supplied at the normal level, but their deficiency leads to different kinds of diseases. The study suggests that the trace elements present in the bark sample of B. dalzielii may be of value and may have prognostic significance in the early diagnosis and therapy evaluation of some diseases, especially various types of cancer, as well as in anti-diabetic agents. The results of the proximate analysis depict the potentiality of the plant as a good source of nutraceuticals.
