										</dc:title><dc:creator>Wu Jian</dc:creator><dc:creator> Yang Tairan</dc:creator><dc:creator> Xu Ying</dc:creator><dc:creator> Zhang Yi</dc:creator><dc:creator>Xiang Zheng</dc:creator><dc:description>&lt;p&gt;&lt;strong&gt;Introduction:&lt;/strong&gt; &lt;em&gt;Hedyotis diffusa&lt;/em&gt; Willd. (Baihuasheshecao) is an ingredient of herbal commonly consumed in China for cancer treatment and health maintenance. In the market, this ingredient is frequently adulterated by the related species &lt;em&gt;Hedyotis corymbosa&lt;/em&gt; Lam.&amp;nbsp;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods:&lt;/strong&gt; The objective of this comparative research is to study the chemical composition of the essential oils from &lt;em&gt;Hedyotis diffusa&lt;/em&gt; WILLD and Hedyotis corymbosa Lam by GC-MS.&amp;nbsp;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Result:&lt;/strong&gt; In total, 43 components were identified in &lt;em&gt;Hedyotis diffusa&lt;/em&gt; Willd. The identified components comprised 11 alcohols, 7 alkenes, 5 ketones, 7 aldehydes, 6 acid substances, 2 esters, 5 other substances. The major components in the &lt;em&gt;Hedyotis diffusa&lt;/em&gt; WILLD oil were Hexadecanoic acid (48.89%) followed by Pentadecanoic acid (6.11%), D-Limonene (5.74%) and fatty acid were the most abundant components in &lt;em&gt;Hedyotis diffusa &lt;/em&gt;WILLD. 32 components were identified in Hedyotis corymbosa (L.) Lam. The identified components comprised 2 alcohols, 8 alkenes, 4 ketones, 1 aldehyde, 6 acid substances, 6 esters, 5 other substances. The major components in the &lt;em&gt;Hedyotis corymbosa&lt;/em&gt; (L.) Lam oil were Hexadecanoic acid (64.93%) followed by Linolenic acid (7.62%), Linoleic acid (3.73%). Borneol, 2-Carene epoxide, cis-Anethol, three compounds were identiﬁed exclusively in &lt;em&gt;Hedyotis diffusa&lt;/em&gt; Willd.&amp;nbsp;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion:&lt;/strong&gt; This study showed that the chemical composition of the essential oils from &lt;em&gt;Hedyotis diffusa &lt;/em&gt;WILLD and &lt;em&gt;Hedyotis corymbosa&lt;/em&gt; Lam GC-MS were different. Borneol, 2-Carene epoxide, cis-Anethol, three compounds were identiﬁed exclusively in &lt;em&gt;Hedyotis diffusa&lt;/em&gt; Willd. This study is signiﬁcant for better quality control of this common herbal ingredient.&lt;/p&gt;</dc:description>
