宽叶木变种Afrodisiaca（Ward）Urb.（syn. T. aphrodisiaca）属于特纳科（Turneraceae），并且是在美洲和非洲的亚热带地区野生生长的芳香植物。它被广泛用于传统医学，例如止咳，利尿和壮阳剂。本工作提出了一个3分钟的色谱分析，使用低压（LP）气相色谱（GC）-离子阱（IT）质谱（MS）。失活的0.6 m x 0.10 mm内径，限流器与大口径CP-Wax 52毛细管柱（10 m × 0.53 mm i.d.，1 μ m）与使用传统的窄孔柱相比，将分析时间减少了3-7倍。优化了色谱条件，以实现MS检测中最快的分离和最高的信噪比。这些结果允许实现精油的快速和可靠的质量控制。(C)2003 Elsevier B.

Turnera diffusa Willd. var. afrodisiaca (Ward) Urb. (syn. T. aphrodisiaca) belongs to the family of Turneraceae and is an aromatic plant growing wild in the subtropical regions of America and Africa. It is widely used in the traditional medicine as e.g. anti-cough, diuretic, and aphrodisiac agent. This work presents a 3 min chromatographic analysis using low-pressure (LP) gas chromatography (GC)-ion-trap (IT) mass spectrometry (MS). The combination of a deactivated 0.6 m x 0.10 mm i.d., restrictor with a wide-bore CP-Wax 52 capillary column (10 m x 0.53 mm i.d., 1 mum) reduces the analysis time by a factor of 3-7 in comparison to the use of a conventional narrow bore column. Chromatographic conditions have been optimized to achieve the fastest separation with the highest signal/noise ratio in MS detection. These results allow fast and reliable quality control of the essential oil to be achieved. (C) 2003 Elsevier B.V. All rights reserved.
