Studies on essential oil composition and the volatile profile of Rhus coriaria from different plant parts are illustrated in the table below.

Plant Part	Technique	Main Results	Ref.
Fruits	GC GC-MS	Over 120 constituents identified. Terpene hydrocarbons (i.e., α-pinene, β-caryophyllene and cembrene), oxygenated terpenes (i.e., α-terpineol, carvacrol and -caryophyllene alcohol), farnesyl acetone, hexahydrofarnesyl acetone and aliphatic aldehydes were the most abundant.	[34]
Branches Leaves Fruits	GC GC-MS	Sixty-three constituents identified with β-caryophyllene and cembrene being the most abundant.	[35]
		Sixty-three constituents identified with β-caryophyllene, sesquiterpene hydrocarbons (patchoulane) being the most abundant.
		Eighty-five constituents identified with limonene, nonanal and (Z)-2-decenal being the most abundant.
Fruits	GC GC-MS	The yield of the was 13.5% (w/w). 21 compounds representing 86.6% of the oils were identified among which β-caryophyllene (30.7%) and cembrene (21.4%) were the major constituents.	[36]
Fruits Leaves	HPLC TLC GLC	Fifty-four constituents identified from which β-caryophyllene, cembrene, (E, E) 2, 4-decadienal and α-terpineol were predominant.	[38]
		65 constituents with β-caryophyllene, caryophyllene oxide, cembrene and α–humulene were predominant.
Fruits	HPLC GLC	Linoleic acid, tocopherols and sterols were predominant.	[39]
Fruits	GC-FID GC-MS HS-SPME	The main constituents were p-anisaldehyde, (Z)-2-heptenal, (E)-2-decenal, β-caryophllene and cembrene	[40]
Stems Closed buds Open buds Leaves Flower buds Flowers Green fruits Green-red fruits Ripe fruits	GC-FID GC-MS HS-SPME	α-pinene, (E)-β-ocimene, limonene, β-pinene (6.1%), myrcene (5.0%) (Z)-β-ocimene were predominant in the stems. β-caryophyllene and cembrene were the main constituents in leaves at all stages of maturation. α-pinene and tridecanoic acid were the major constituents in the flower.	[41]
Fruits	GC-FID GC-MS	Fifty-seven constituents were identified in the essential oil of sumac fruits collected from 14 different regions in Iran. (E)-Caryophyllene, n-nonanal (1.8–23.3%), cembrene (1.9–21.7%), α-pinene (0.0–19.7%), (2E,4E)-decadienal (2.4–16.5%) and nonanoic acid (0.0–15.8%) were identified as the main constituents	[42]
