However, those products do not discriminate the varieties of &lt;em&gt;Ficus deltoidea&lt;/em&gt; used. &lt;strong&gt;Methods:&lt;/strong&gt; FTIR-based metabolomics coupled with chemometric technique was applied to discriminate chemical components in ethanolic extracts of syconia of seven varieties of &lt;em&gt;Ficus deltoidea&lt;/em&gt; namely; var. &lt;em&gt;deltoidea&lt;/em&gt;, var. &lt;em&gt;trengganuensis&lt;/em&gt;, var. &lt;em&gt;kunstleri&lt;/em&gt;, var. &lt;em&gt;angustifolia&lt;/em&gt;, var. &lt;em&gt;bilobata&lt;/em&gt;, var. &lt;em&gt;intermedia&lt;/em&gt; and var. &lt;em&gt;motleyana&lt;/em&gt;. Unsupervised multivariate data analysis (MVDA) including principal component analysis (PCA) was used as to evaluate chemical variability among the seven varieties. For discrimination, orthogonal partial least square discriminant analysis (OPLS-DA) was applied, while partial least square (PLS) was used to evaluate the relationship between the alpha-glucosidase inhibition, antioxidant activity and&lt;em&gt; Ficus deltoidea&lt;/em&gt; varieties. &lt;strong&gt;Results:&lt;/strong&gt; As a result, OPLS-DA successfully discriminated the seven varieties. The FTIR fingerprints which were responsible for the discrimination includes 1729, 1705, 1448, 1095, 453, 443 cm-1. In addition, PPLS model demonstrated the correlation between var. &lt;em&gt;kunstleri&lt;/em&gt;, var. &lt;em&gt;deltoidea&lt;/em&gt; and var. intermedia respective chemicals fingerprints and their bioactivity (DPPH, FRAP and &amp;alpha;-glucosidase inhibition). &lt;strong&gt;Conclusion:&lt;/strong&gt; The findings revealed that FTIR spectroscopy, in combination with MVDA, can be used for structural functional discrimination in relation to the sample bioactivity.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6s</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">s147</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Alkasim Kabiru Yunusa&lt;sup&gt;1,4&lt;/sup&gt;, Zalilawati Mat Rashid&lt;sup&gt;*1,2&lt;/sup&gt;, Nashriyah Mat&lt;sup&gt;1&lt;/sup&gt;, Che Abdullah Abu Bakar&lt;sup&gt;1&lt;/sup&gt;, Abdul Manaf Ali&lt;sup&gt;1,2,3 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
