Typically, the oleoresin of boswellia is reported to be composed of
- Vegan: Derived from non-animal sources
- Each digestive enzyme in the blend is food-grade, Non-GMO and gluten-free
- Sesquiterpenoid essential oils (8 – 12%)
- Polysaccharides (45 – 60%)
- Higher terpenoids, including boswellic acids (25 – 35%)
The gum resin of B. serrata to contains
- Monoterpenes (α-thujene)
- Diterpenes (Macrocyclic diterpenoids such as incensole, incensole oxide, inoincencole oxide, a diterpene alcohol (serrtol))
- Triterpenes (such as α- and β-amyrins)
- Tetracyclic triterpenic acids (Tirucall-8, 24-dien-21-oic acids)
- Pentacyclic triterpenic acids (Boswellic acids)
The four major pentacyclic triterpenoids identified in Boswellin® are
- β-boswellic acid
- Acetyl-β-boswellic acid
- 11-keto-β-boswellic acid
- Acetyl-11–keto–β-boswellic acid
