本研究の目的は、一般的な食品の腐敗や病原性微生物に対するsubps.精油(EO)の抗菌性を調べ、その抗酸化活性と抗増殖活性を評価することであった。EOは水蒸気蒸留法で分離し、GC/MSで分析した。主な成分は、ゲラニル--シメン(25.08%)、ゲラニル--テルピネン(15.17%)、ゲラニル-リナロール(14.04%)であった。その後、最小阻害濃度(MIC)、非阻害濃度(NIC)、最小致死濃度(MLC)を決定した。その結果,陽性対照として使用したゲンタマイシン,シプロキシン,ボリコナゾールに比べて有意に低いものの,すべての微生物の生育阻害が確認された。次のステップでは,2,2-ジフェニル-1-ピクリルヒドラジル(DPPH)および2,2'-アジノビス(3-エチルベンゾチアゾリン-6-スルホン酸)(ABTS)アッセイを用いて,その直接的な抗酸化特性を調べ,IC値を決定した。HO誘発酸化ストレスとDNA損傷に対するオイルの潜在的な細胞保護活性は、コメットアッセイを使用してヒト不死化ケラチノサイト(HaCaT)細胞で研究されました。最後に、スルフォルホダミンB(SRB)アッセイを用いて、A375、Caco2、PC3、DU145を含む癌細胞株と非癌性のHaCaT細胞株に対してオイルの抗増殖活性を評価し、EC値を決定した。オイルは、弱いラジカル消去活性を示し、HaCaT細胞のHO誘発酸化ストレスとDNA損傷に対する細胞保護活性、およびすべての細胞株に対して抗増殖活性を示し、皮膚メラノーマのモデルに対してより敏感であった。
The aim of the present study was to investigate the antimicrobial potential of subps. essential oil (EO) against common food spoilage and pathogenic microorganisms and evaluate its antioxidant and antiproliferative activity. The EO was isolated by steam distillation and analyzed by GC/MS. The main constituents identified were geranyl--cymene (25.08%), geranyl--terpinene (15.17%), and geranyl-linalool (14.04%). Initially, its activity against , , , , Enteritidis, Typhimurium, , and was screened by the disk diffusion method. Subsequently, minimum inhibitory concentration (MIC), non-inhibitory concentration (NIC), and minimum lethal concentration (MLC) values were determined. Growth inhibition of all microorganisms tested was documented, although it was significantly lower compared to gentamycin, ciproxin, and voriconazole, which were used as positive controls. In a next step, its direct antioxidant properties were examined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays, and the IC values were determined. The potential cytoprotective activity of the oil against HO-induced oxidative stress and DNA damage was studied in human immortalized keratinocyte (HaCaT) cells using the comet assay. Finally, the antiproliferative activity of the oil was evaluated against a panel of cancer cell lines including A375, Caco2, PC3, and DU145 and the non-cancerous HaCaT cell line using the sulforhodamine B (SRB) assay, and the EC values were determined. The oil demonstrated weak radical scavenging activity, noteworthy cytoprotective activity against HO-induced oxidative stress and DNA damage in HaCaT cells, and antiproliferative activity against all cell lines tested, being more sensitive against the model of skin melanoma.
