This study aims to study the chemical components from the gum resin of Boswellia carterii. Five cembranoid diterpenes were isolated from the gum resin of B. carterii by various of column chromatographies including silica gel, Sephadex LH-20, and semi-preparative HPLC. Their structures were identified on the basis of physicochemical properties, mass spectrometry(MS), nuclear magnetic resonance(NMR), Ultraviolet(UV) and infrared(IR) spectroscopic data. These compounds were identified as(1S,2E,4R,5S,7E,11E)-4-methoxy-5-hydroxycembrane(1),(1R~*,4R~*,5E,8E,12E,15E)-4-hydroxycembra-5,8,12,15-tetraene(2), cembrene A(3),(3S,4S,7R)-4-hydroxycembrane(4), and pavidolide D(5). Compound 1 was a new compound. Compounds 2, 4, and 5 were obtained from the gum resin of B. carterii for the first time. Compound 2 showed weak inhibition on the human liver cancer cell line HepG2.

Background: Gingival recession has a multifactorial etiology, involving various predisposing and precipitating factors. Non-carious cervical lesions (NCCLs) are often associated with gingival recession and pose challenges due to their complex pathodynamics. There is limited evidence regarding tunnel-based procedures combined with connective tissue grafts (CTGs) for treating recession-associated NCCLs.

The pathogenesis of psoriasis involves hyperproliferation of epidermal keratinocytes and abnormal interactions between activated keratinocytes and infiltrating immune cells. Emerging evidence has shown that keratinocytes play essential roles in both the initiation and maintenance of psoriasis, suggesting that exposing keratinocytes to agents with antiproliferative and anti-inflammatory effects may be effective for psoriasis treatment. Guggulsterone (GS), a plant sterol derived from the gum resin of Commiphora wightii, possesses a variety of pharmacological activities.

Being a central organ in homeostasis and maintaining the health of the biological system, kidneys are exposed to variable toxicants. Long-term exposure to nephrotoxic molecules causes chronic renal damage that causes fibrosis and loss of function. Such damage can be initiated by oxidative stress which provokes inflammation.
