Study of component structure of essential oil of above-ground parts of Bupleurum Scorzonerifolium which grows in the Baikal Region

Constituents of Essential Oil and Lipid Fraction from the Aerial Part of Bupleurum scorzonerifolium Willd. (Apiaceae) from Different Habitats

“…Components of essential oils extracted from plants originating from Mongolia were monoterpenes: β -myrcene (0.62–8.35%), cis - β -ocimene (0.37–9.22%), trans - β -ocimene (0.49–3.08%), limonene (2.64–7.08%), γ -terpinene (0.09–2.53%), α -pinene (0.11–5.62%), β -pinene (0.92–8.09%); sesquiterpenes: β -elemene (1.16–3.68%), humulene (1.71–14.66%), germacrene D (15.56–41.34%), caryophyllene (3.91–12.83%), bicyclogermacrene (3.53–7.61%), caryophyllene oxide (0.71–7.30%), spathulenol (0.63–7.42%); and aromatic compounds: p -cymol (0.18–10.56%). Comparison with data from the literature [ 7 , 8 , 9 , 10 ] showed that cis - β -ocimene, trans - β -ocimene, limonene, α -pinene, α -copaene, β -elemene, and caryophyllene oxide were consistent components in the essential oil of B. scorzonerifolium ’s aerial parts, regardless of habitat. The contents of these components varied from traces to a significant amount.…”

“…Samples from the Krasnoyarsk region were characterized by an accumulation of trace amounts of compounds such as geranyl acetate, γ -bisabolene, iso -elemicin, epi - α -bisabolol, iso -caryophyllene, t -cadinol, δ -cadinol, iso -spathulenol, benzyl alcohol, asarone, n -octyl butanoate, dihydrocitronellol, linalyl butanoate, salicylaldehyde, and pentadecanal [ 7 , 8 ]. Monoterpenes: α -fellandrene, (1 S ,5 S )-2(10)-pinene, δ -3-carene, p -mentha-1,3,8-diene-6-ol; and sesquiterpenes: γ -elemene, seychellene, β -guaiene, γ -gurjunene, γ -himachalene, naphthalene,1,2,4a,5,8,8a-hexahydro-4,7-dimethyl-1-(1-methylethyl)-[1 S -(1 α ,4a β ,8a α )]-, 9-methoxy-calamene, aromadendrene oxide-(2), iso -aromadendrene epoxide, muurolan-3,9(11)-dien-10-peroxide, and ledene oxide were specific for samples from the Irkutsk region [ 9 ].…”

“…Brown-filled circle (mng2010) is according to [ 10 ]. “Irkutsk” indicates the B. scorzonerifolium sample from the Irkutsk region (Russia) according to [ 9 ]. “Krasnoyarsk” indicates the B. scorzonerifolium sample from the Krasnoyarsk region (Russia) according to [ 7 , 8 ].…”

“…Previous studies have been dedicated to the chemical constituents of essential oils of the aerial parts of B. scorzonerifolium growing within Russia, in particular, the Krasnoyarsk region [ 7 , 8 ], Irkutsk region [ 9 ], and Mongolia [ 10 ]. One study also provided detailed information about the essential oils extracted from the roots of plants growing in China [ 11 ].…”

Dynamic Changes in the Composition of Biologically Active Compounds of Bupleurum Scorzonerifolium Willd. Aerial Part in Different Phenological Phases

“…Есть сведения о составе эфирных масел и липидной фракций растений этого вида, произрастающих на территории Забайкалья, Монголии и Китая [3]. В литературе также имеется ряд работ: изучен состав флавоноидов нескольких видов володушек, в том числе B. scorzonerifolium флоры Бурятии [4], исследованы фенольные соединения, эфирные масла, элементный состав володушки козельцелистной, произрастающей в Прибайкалье [5][6][7][8][9][10][11]. Однако известно, что накопление биологически активных соединений (БАС) в растениях в течение вегетационного периода является динамическим процессом, зависящим от многочисленных факторов окружающей среды [12].…”
