Abstract
Fast gas chromatography-surface acoustic wave sensor (GC/SAW) has been applied for the detection of the pharmacological volatiles emanated from Houttuynia cordata Thunb which is from South Korea. H. cordata Thunb with unpleasant and fishy odors shows a variety of pharmacological activities such as anti-microbial, anti-inflammatory, anti-cancer, and insect repellent. The aim of this study is to show a novel quality control by GC/SAW methodology for the discrimination of the three different parts of the plant such as leaves, aerial stems, and underground stems for H. cordata Thunb. Sixteen compounds were identified. β-Myrcene, cis-ocimene and decanal are the dominant volatiles for leaves (71.0%) and aerial stems (50.1%). While, monoterpenes (74.6%) are the dominant volatiles for underground stems. 2-Undecanone (1.3%) and lauraldehyde (3.5%) were found to be the characteristic components for leaves. Each part of the plant has its own characteristic fragrance pattern owing to its individual chemical compositions. Moreover, its individual characteristic fragrance patterns are conducive to discrimination of the three different parts of the plant. Consequently, fast GC/SAW can be a useful analytical method for quality control of the different parts of the plant with pharmacological volatiles as it provides second unit analysis, a simple and fragrant pattern recognition.

The only difference is the proportion of such components present. Such differences lead to the discrimination of three different parts of the plant such as leaves, aerial stems, and underground stems of H. cordata Thunb
Summary
Perennial Houttuynia cordata Thunb (Saururaceae) is an important medicinal plant in Asia. The chemical components of H. cordata Thunb comprise of volatiles, flavonoids, alkaloids, fatty acids, sterols, and polyphenolic acids [1]. Its volatile components have many clinical benefits including anti-microbial, anti-inflammatory, anti-cancer, anti-fungal, anti-bacterial, and insect repellent [2]. The analysis of volatile constituents of H. cordata Thunb is of great interest in clinical therapy and food industries. The analysis of volatiles from the plant material is preceded by isolation procedures including solvent extraction [3], steam distillation [4], and simultaneous distillation extraction [5], which involve excessive manipulation of the sample, a very costly, time-consuming procedure, low extraction efficiency, losses of some volatile compounds, and degradation of volatiles. The analysis of volatile compounds demands rapid and simple procedures, because volatile components are sensitive and decompose when exposed to new chemical components in air or light
