The Effects of Aqueous Extract of Boswellia Serrata on Memory Impairment Induced by Lipopolysaccharide

Abstract

Background and Aims: The therapeutic effects of the olibanum, the resin of Boswellia serrata (B. serrata) from the Burseraceae family in inflammatory disease have been reported. There are more than 200 active ingredients in this resin, including Boswellic acid. It is proposed that aqueous extract of B. serrata can improve memory impairment induced by cerebral inflammation result in the administration of lipopolysaccharide (LPS).
 Materials and Methods: In this study, after the treatment of rats with LPS, brain toxicity induction was performed, and finally, the behavioral tests were evaluated. Following cerebral inflammation induction and treatment, behavioral performance biochemistry tests and molecular methods were assessed in all groups.
 Results: LPS administration increased the duration and distance to find the platform in the Morris water maze test compared to the control group in 5 days (p<0.05 to p<0.001). Furthermore, LPS reduced the peripheral, central, and total locomotion compared to the control group (p< 0.001) in the open field test. Pretreatment with both doses of aqueous extract of B. serrata enhanced performances of the rats in Morris water maze (p<0.05 to p<0.01) and open field test (p<0.01 to p<0.001). LPS also increased hippocampus Interleukin-6, malondialdehyde levels (p<0.001).
 Conclusion: Aqueous extract of B. serrata can be a useful drug in memory impairment caused by LPS-induced inflammation.

Glycyrrhizin and boswellic acids, the golden nutraceuticals: multitargeting for treatment of mild–moderate COVID-19 and prevention of post-COVID cognitive impairment

“…It works by inhibiting inflammation and oxidative stress. It may modulate the activity of multiple molecular targets that influence the signaling pathways that contribute to the pathogenesis of cognitive impairment (Borooni et al 2020 ; Marefati et al 2020 , 2021 , 2022 ). Mohammed et al (2022) observed that BA modulated the expression of parameters related to the Wnt/-catenin pathway and decreased the expression of TNF-α IL-1β, attenuated lipid peroxidation, and raised total brain antioxidants.…”

Effects of Ziziphus Jujuba Extract Alone and Combined with Boswellia Serrata Extract on Monosodium Iodoacetate Model of Osteoarthritis in Mice

“…Spinosa seeds exhibited significant anti-depressant-like effects by increasing the mobility time and total distance in the force swimming and open field tests ( 32 ). In previous studies, pretreatment with an aqueous extract of B. serrata enhances the rats' performances in the Morris water maze and open field tests and corrects memory impairment in LPS-induced inflammation ( 33 ). Similarly, boswellic acids (BAs) and pentacyclic triterpene molecules enhance locomotor performance, reduce inflammatory factors, and increase striatal dopamine levels in rats with rotenone-induced parkinsonism ( 34 ).…”
