Abstract

Objective: The component composition of the essential oil (EO) obtained by hydrodistillation from the air-dry and fresh aboveground parts of the plant Perovskia angustifolia Kudr., growing on the territory of the Namangan region of the Republic of Uzbekistan has been studied. Methods: By GC-MS, 57 compounds were identified in the composition of the EO from the air-dried plant, while 46 substances were found in the composition of the EO from the fresh plant, which is 94.0 and 96.2% of the total amount of EOs, respectively. Results and Discussion: The main EO components of both the air-dry and fresh aerial parts are 1,8-cineole, its content is 24.2, and 25.1%, respectively. EO from an air-dry plant contains camphor (8.6%), endoborneol (7.3%), bornyl acetate (6.2%), caryophyllene (4.4%), α-humulene (4.1%), δ-cadinene (3.8%) and other connections. The dominant components in the composition of EO from a fresh plant, in addition to 1,8-cineol, are camphor (13.8%), endoborneol (8.6%), bornyl acetate (7.0%), γ-terpinene (7.0%), m-cimene (5.2%), Δ-3-karen (4.5%), δ-kadinen (2.9%). The aerial part of P. angustifolia can serve as a rich source of 1,8-cineole, which is used in bronchitis, colds of the respiratory tract, chronic and inflammatory respiratory diseases. Conclusions: EO from the aerial part of the air-dry P. angustifolia exhibits a noticeable antimicrobial and antifungal effect against test strains of Gram-positive, Gram-negative bacteria, while gram-positive bacteria Bacillus subtilis and Staphylococcus aureus turned out to be the most sensitive to the effects of essential oil.

枳实精油的成分组成及抑菌活性研究
目的:对空气干燥和空气新鲜的枇杷叶地上部分进行加氢蒸馏法提取精油的成分组成进行研究。研究了生长在乌兹别克斯坦共和国纳曼甘地区领土上的一种红毛茛。方法:采用气相色谱-质谱联用技术,在风干植物提取物中鉴定出57种化合物,在新鲜植物提取物中鉴定出46种物质,分别占提取物总量的94.0和96.2%。结果与讨论:风干和新鲜空气部位的主要EO成分均为1,8-桉树脑,其含量分别为24.2%和25.1%。从一种风干植物中提取的EO含有樟脑(8.6%)、冰片内醇(7.3%)、龙脑醋酸酯(6.2%)、石竹烯(4.4%)、α-葎草烯(4.1%)、δ-仙人掌烯(3.8%)等连接物。从新鲜植物中提取的EO中,除1,8-桉叶醇外,主要成分为樟脑(13.8%)、龙脑内(8.6%)、龙脑醋酸酯(7.0%)、γ-松油烯(7.0%)、间-亚胺(5.2%)、Δ-3-karen(4.5%)、δ-卡丁宁(2.9%)。刺叶的空气部分可以作为1,8-桉树脑的丰富来源,用于支气管炎,呼吸道感冒,慢性和炎症性呼吸道疾病。结论:风干荷叶根部精油对革兰氏阳性菌和革兰氏阴性菌均有明显的抑菌抑菌作用,而革兰氏阳性菌枯草芽孢杆菌和金黄色葡萄球菌对精油的作用最为敏感。

期刊介绍: Russian Journal of Bioorganic Chemistry publishes reviews and original experimental and theoretical studies on the structure, function, structure–activity relationships, and synthesis of biopolymers, such as proteins, nucleic acids, polysaccharides, mixed biopolymers, and their complexes, and low-molecular-weight biologically active compounds (peptides, sugars, lipids, antibiotics, etc.). The journal also covers selected aspects of neuro- and immunochemistry, biotechnology, and ecology.
