_Cinnamorum verum_ (old name _C. zeylanicum_) is known as the true or Ceylon cinnamon tree native to Sri Lanka [5]. However, other _Cinnamomum_ species, including _C. cassia_ (Chinese cinnamon), are also consumed as possible alternatives [4], in addition to _C. burnamiii_ (Korintje, Java, or Indonesian cinnamon), _C. loureiroi_ (Vietnamese or Saigon cinnamon), _C. tamala_, and _C. iners_[6; 7]. _Cinnamomum_ sp. are rich in bioactive metabolites, particularly phenylpropanoids abundant in leaf and inner bark essential oil, where eugenol and (_E_)-cinnamaldehyde are the major constituents, respectively [8]. Particularly, I-cinnamaldehyde represents 60-75% of the essential oil derived from official _C. verum_ bark [5] as the most valued drug in that genus to date. Compared to _C. verum_, _C. cassia_ is recognized as a lower grade owing to its richness in the toxic compound \"coumarin\" and lower content I(_E_)-cinnamaldehyde [9]. In terms of non-volatile bioactives, cinnamon bark contains a wide spectrum of polyphenics such as flavonoids, proanthocyanidins, and tannins [10]. Cinnamon in modern medicine exhibit antitumor effects via dual mechanisms, i.e., upregulation of proapoptotic molecules and inhibition of NF-\(\kappa\beta\) and AP1 and their associated genes Bcl-2, Bcl-xL, and survivin [5]. In addition, it exerts anti-diabetic effects via inhibition of \(\alpha\)-amylase and \(\alpha\)-glucosidase enzymes [11], recommended as flavor agents for patients with type-2 diabetes mellitus [12]. Hence, several products containing cinnamon as the major constituent are available commercially for several health benefits. Yet, the origin of these products is not always stated with no clear declaration of the cinnamon type, including exposing the consumers to potential toxicities of chemicals such as coumarin or through drug-food interactions with patients treated simultaneously with warfarin [13]. In terms of volatile organic compounds (VOCs), previous literature has commonly employed gas chromatography coupled with mass spectrometry (GC-MS) in the analysis of cinnamon essential oils extracted by steam distillation. Several VOCs were identified, where (_E_)-cinnamaldehyde, linalool, and eugenol were among the chief component by 71.5%, 7.0%, and 4.6%, respectively [14]. However, head space-solid phase micro-extraction (HS-SPME) was developed as a pre-concentration step and furtherly improved by coupling to GC-MS is a potential analytical method for aromatic herbal products [15]. Currently, solid-phase microextraction coupled to GC-MS (SPME/GC-MS) is devoted to the analysis of VOCs of low molecular weights. Asides, ultraviolet/visible (UV/Vis) spectrometry is advantageously employed as a cheap and non-destructive method for fingerprinting, albeit with its low structural identification power [15; 16]. Moreover, nuclear magnetic resonance (NMR) is a powerful tool and has been recently used apart from liquid chromatography coupled to MS (LC/MS) technique for the identification of the key metabolites in different herbal crude extracts evidenced by various 1D and 2D techniques [17]. Handling the huge data generated by these platforms represents a challenge for metabolomics experts to extract valuable information aiding in sample classification, standardization, and authentication. Hence, chemometrics and multivariate data analyses (MVA) are potential candidates for such purposes, including unsupervised tools such as principal component analysis (PCA) and supervised orthogonal projections to latent structures discriminant analysis (OPLS-DA) [15]. Therefore, metabolomics-based profiling, fingerprinting, and processing of herbal products have been well documented meanwhile for quality assessment purposes, where various direct and indirect analytical platforms are used to target certain classes of phytoconstituents [18; 19; 20].
