摘要: 采用水蒸气蒸馏法提取海南产神秘果叶挥发油,利用气相色谱-质谱联用技术(GC-MS)分析挥发油的化学成分,并对挥发油的抑菌和抗肿瘤活性进行了评价。结果从挥发油中共分离出68个化合物,鉴定出44种化学成分,占挥发油总质量分数的92.14%。其中质量分数较高的组分为匙叶桉油烯醇(24.194%),柠檬烯(15.805%),邻苯二甲酸二异辛酯(12.402%),邻苯二甲酸二丁酯(10.326%),棕榈酸(4.865%)和芳樟醇(2.139%)。体外抗菌试验的结果表明,神秘果叶挥发油除了对绿脓杆菌没有明显的抑制作用,对其他7个试验菌株均具有较好的抑菌活性,最小抑菌浓度(MIC)范围为39.06~252.15 mg/L。抗肿瘤活性试验的结果表明,神秘果叶挥发油能够有效抑制人白血病细胞K562的增殖,半数抑制浓度(IC50)值为13.5 mg/L。

Abstract: The aim of this study was to determine the chemical composition of Synsepalum dulcificum leaf essential oil obtained by steam distillation. The in vitro antibacterial activity and antitumoral activity of this essential oil was characterized. Sixty-eight compositions were separated. Among them 44 components were identified and represented 92.14% of the total detected constituents. The major chemical compounds of leaf essential oil were spathulenol (24.194%), limonene (15.805%), diisooctyl phthalate (12.402%), dibutyl phthalate (10.326%), palmitic acid (4.865%) and linalool (2.139%). The result of the antimicrobial assay showed that the essential oil displayed varying degrees of antibacterial activity against all tested bacterial except for Pseudomonas aeruginosa, along with minimum inhibition concentration(MIC)values from 39.06 to 252.15 mg/L. In addition, the antitumoral activity using MTT assay of the leaf essential oil exhibited this oil was effective against human K562 cancer cell line in a dose dependent manner. Its inhibition concentration 50% (IC50) value was 13.5 mg/L.
