摘要:

对广东南岭自然保护区内野生的毛桃木莲( Manglietia moto ) 、乳源木莲( M1 yuyanensis ) 、乐昌含笑
( M1 chapensis ) 、金叶含笑(M1foveolata) 和深山含笑( M1 maudiae) 5 种木兰科芳香植物精油进行了化学成
分对比分析和抗氧化活性研究。化学成分鉴定采用气质联用技术, 同时结合了保留指数比较法; 精油抗氧
化活性采用B- 胡萝卜素漂白试验法。深山含笑芳香精油的主体成分以单萜烯为主, 另外4 种木兰科芳香精
油所含成分均以倍半萜类为主。毛桃木莲和乳源木莲精油在成分构成上具有高度一致性, 而且在主要成分
上具有相似性, 这可能表明它们具有非常近的植物亲缘关系。4 种精油的抗脂质氧化半抑制浓度分别为
616 gPL ( 毛桃木莲精油) 、91 8 gPL ( 乳源木莲精油) 、1113 gPL) 金叶含笑精油) 和1212 gPL ( 乐昌含笑精
油) , 在本试验条件下, 未能测出深山含笑的半抑制浓度。

Abstract:

The essential oils of five Magnoliaceae plants, namely Manglietia moto Dandy , Manglietia y uyanensis Law,
Michelia chap ensis Dandy, Michelia foveolata Merr. ex Dandy, and Michelia maudiae Dunn, growing wild in Nanling
National Nature Reserve of Guangdong province, were analyzed for their chemical composition and tested for their antiox-i
dant effectiveness. The GC-MS analyses as well as comparison of the retention indices ( RI) of elution peaks with literature
data were used in compound identification of the essential oils; the B- carotene bleaching ( BCB) test method was used in
the preliminary evaluation of antioxidant activities for them. The M1 maudiae oil characterizes high contents of monoterpenes,
while other four oils are all constituted mainly by sesquiterpenoids. The high consistence of composition and similar-i
ties in major constituents between the M1 moto and M1 yuyanensis oils may indicate their close correlation between relatives.
The 50% inhibition were accomplished with 616 gPL of M1 moto oil, 918 gPL of M1 yuyanensis oil, 111 3 gPL of
M1f oveolata oil and 1212 gPL of M1 chap ensis oil, respectively , whereas M1 maudiae oil could not inhibit 50% of the
bleaching reaction under the test conditions.
