Chemical Composition of the Essential Oil ofBupleurum exaltatumM.B. Growing Wild in Iran

Abstract

The chemical composition of the volatile oil from aerial parts of Bupleurum exaltatum M.B. has been studied by GC-MS for first time. Forty-nine components (97.3 % of the total composition) were identified. (E)-β-farnesene (29.8 %), germacrene-D (13.3 %), spathulenol (12.9 %), bicyclogermacrene (4.1 %), caryophyllene oxide (3.9 %), myrcene (3.5 %) and α-humulene (3.1 %) were found to be the major constituents of the oil. The oil of B. exaltatum was characterized by a high content of sesquiterpenes (82.2 %), whereas monoterpenes contained only 10.6 % of the essential oil. Non-terpenic compounds were also consisted 4.5 % of the oil.

Hypericum Essential Oils—Composition and Bioactivities: An Update (2012–2022)

“…Moreover, significant variability has been documented for the EOs of H. triquertifolium, which, when collected in Greece, yielded either high amounts of α-pinene together with β-caryophyllene [22] or high percentages of β-caryophyllene and very low quantities of α-pinene [31]. Much diversity has been reported for this plant when collected from different populations in Tunisia [45], while the oils from Iran and Turkey were abundant in germacrene-D and hexanal, respectively [29,50]. Tahir et al [25] characterized the EO from H. triquetrifolium cultures produced by the root and stem for the first time and cited that alkane, aldehyde, and monoterpene compounds are the foremost fractions.…”

Determination of essential oil and biological activities of Hypericum ternatum Poulter and H. scabrum L. species collected from different localities: is H. scabrum an alternative to multifunctional species ST JOHN'S WORT (H. perforatum)?

“…spathulatum Rabson [ 6 ]; germacrene-D (21.7%), β-caryophyllene (18.3%), and δ-cadinene (6.4%) for H. triquetrifolium Turra. [ 7 ] were identified as their major compounds. Similar studies reported also that α-pinene (31.9 ± 1.9%), (E)-β-ocimene (12.5 ± 1.0%), β-phellandrene (8.4 ± 1.1%), and β-pinene (6.3 ± 0.4%) for H. helianthemoides (Spech) Boiss [ 8 ]; α-pinene (19.0%), germacrene D (12.5%), and β-pinene (8.7%) for H. empetrifolium Willd [ 9 ]; β-selinene (15%), caryophyllene oxide (9%), β-caryophyllene (8%), and γ -muurolene (7%) for H. pruinatum Boiss [ 10 ]; α-pinene (57.3%), β-pinene (9.0%), and limonene (6.2%) for H. hyssopifolium Chaix.…”
