<p><strong>Introduction:</strong> <em>Hedyotis diffusa</em> 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 <em>Hedyotis corymbosa</em> Lam. </p><p><strong>Methods:</strong> The objective of this comparative research is to study the chemical composition of the essential oils from <em>Hedyotis diffusa</em> WILLD and Hedyotis corymbosa Lam by GC-MS. </p><p><strong>Result:</strong> In total, 43 components were identified in <em>Hedyotis diffusa</em> 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 <em>Hedyotis diffusa</em> 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 <em>Hedyotis diffusa </em>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 <em>Hedyotis corymbosa</em> (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 <em>Hedyotis diffusa</em> Willd. </p><p><strong>Conclusion:</strong> This study showed that the chemical composition of the essential oils from <em>Hedyotis diffusa </em>WILLD and <em>Hedyotis corymbosa</em> Lam GC-MS were different. Borneol, 2-Carene epoxide, cis-Anethol, three compounds were identified exclusively in <em>Hedyotis diffusa</em> Willd. This study is significant for better quality control of this common herbal ingredient.</p>
