Quantitative analysis for the quality control of Boswellia carterii.

Compounds	Method	Result	Reference
Acetyl-11-keto-β-boswellic acid Acetyl-β-boswellic acid β-Boswellic acid α-Boswellic acid Acetyl-α-boswellic acid 11-Keto-β-boswellic acid Acetyl-lupeolic acid Lupeolic acid Acetyl-9,11-dehydro-α-boswellic acid 9,11-Dehydro-α-boswellic acid Acetyl-9,11-dehydro-β-boswellic acid 9,11-Dehydro-β-boswellic acid	HPLC	The contents of acetyl-11-keto-β-boswellic acid, acetyl-β-boswellic acid, ß-boswellic acid, α-boswellic acid, acetyl-α-boswellic acid, 11-keto-β-boswellic acid, acetyl-lupeolic acid, lupeolic acid, acetyl-9,11-dehydro-α-boswellic acid, 9,11-dehydro-α-boswellic acid, acetyl-9,11-dehydro-β-boswellic acid, and 9,11-dehydro-β-boswellic acid were 40.0, 39.8, 37.2, 26.9, 21.1, 10.1, 7.8, 2.3, 0.28, 0.15, 0.06, and 0.04 mg/g, respectively	[44]
α-Thujene α-Pinene α-Phellandrene	GC-MS	The α-thujene (69.16%), α-pinene (7.20%), and α-phellandrene (6.78%) were the major components of tested essential oil by GC-MS analysis	[47]
α-Pinene	GC/MS, UV	B. carterii can be distinguished from B. scar by comparing optical rotation and chirality. However, storage time and storage conditions increase the variability of the α-pinene content, which is related to its optical rotation	[48]
α-Pinene α-Phellandrene Sabinene Bornyl acetate	GC/MS	The contents of α-pinene, α-phellandrene, sabinene, and bornyl acetate were 3.11%, 0.03%, 0.26%, and 0.09%, respectively	[2]
α-Pinene Isoincensole acetate	GC/MS	The fibre coating material, sampling temperature, and sampling time will affect the test results. The polydimethylsiloxane/divinylbenzene (PDMS/DVB) fibre ageing was found as the most effective method to capture the diterpene characteristics of olibanum, with a sampling time of 1 h and a sampling temperature of 80°C. The contents of α-pinene and isoincensole acetate in PDMS/DVB fraction were 4.0% and 8.2%, respectively	[13]
α-Pinene Isoincensole acetate	GC/MS	The contents of α-pinene and isoincensole acetate in CH2Cl2 extraction of B. carterii were 3.6% and 40.4%, respectively
ß-Caryophyllene oxide	TLC	ß-caryophyllene oxide was a significant marker compound of B. carterii/sacra	[11]
α-Pinene α-Thujene Methoxydecane	GC-MS	Environmental and human factors resulted in 42 samples of B. carterii essential oil exhibited three different chemotypes	[49]
