The identification of adulteration practices of medicinal plants used as herbal medicine is very important to ensure the quality, safety, and efficacy. In this study, thin layer chromatography (TLC) and proton nuclear magnetic resonance (1H-NMR)-based metabolite fingerprinting coupled with multivariate analysis were used for authentication of Curcuma xanthorrhiza extract from Curcuma aeruginosa. Curcumin contents obtained from C. xanthorrhiza extract from various regions were in the range of 0.74%–1.23%. Meanwhile, curcumin contents obtained from C. xanthorrhiza extract adulterated with 0%, 10%, 25%, 40%, 50%, and 75% of C. aeruginosa were 1.02%, 0.96%, 0.86%, 0.69%, 0.43%, and 0.27%, respectively. The decreasing of curcumin contents in adulterant concentrations of 40% and more in C. xanthorrhiza rhizome could indicate the adulteration with other rhizomes. Multivariate analysis of PCA (principal component analysis) using data set obtained from 1H-NMR spectra clearly discriminated pure and adulterated C. xanthorrhiza with C. aeruginosa. OPLS-DA (orthogonal projections to latent structures-discriminant analysis) successfully classified pure and adulterated C. xanthorrhiza with higher R2X (0.965), R2Y (0.958), and Q2(cum) (0.93). It can be concluded that 1H-NMR-based metabolite fingerprinting coupled with PCA and OPLS-DA offers an adequate method to assess adulteration practice and to evaluate the authentication of C. xanthorrhiza extracts.

Temulawak (Curcuma xanthorrhiza Roxb) merupakan salah satu jenis tanaman unggulan yang banyak dimanfaatkan masyarakat. Pencampuran adulteran pada bahan baku sediaan temulawak dapat membahayakan kesehatan. Penelitian ini bertujuan untuk mendeteksi adulteran pada bahan baku sediaan temulawak instan. Metode yang digunakan adalah Thin Layer Chromatography (TLC) fingerprint analysis. Sidik jari KLT temulawak dibuat menggunakan rimpang temulawak yang berasal dari Cianjur, Semarang, dan Nusa Tenggara Timur. Sementara sidik jadi kunyit (Curcuma longa)sebagai adulteran utama dibuat menggunakan rimpang kunyi dari Cianjur. Ekstraksi dilakukan dengan metode maserasi menggunakan pelarut etanol 96%. Analisis kromatogram secara kemometrik menggunakan metode Principal Component Analysis (PCA). Nilai loadings Principal Component 1 (PC1) menunjukkan kurva yang linier dan data hasil scores PC1 tersebut dapat membedakan dengan baik sidik jari temulawak dari kunyit dengan nilai scores temulawak dan kunyit berada pada kuadran yang berbeda. Hasil menunjukkan bahwa nilai scores ketiga sampel temulawak instan berada di antara kuadran temulawak dan kunyit (Curcuma Longa L). Dapat disimpulkan bahwa semua sampel positif mengandung adulteran pada temulawak instan.

Turmeric (Curcuma longa), java turmeric (Curcuma xanthorrhiza) and cassumunar ginger (Zingiber cassumunar) are widely used in traditional Indonesian medicine. These three herbs have relatively similar rhizomes colour so it is difficult to be differentiated especially if they are in powder form. A rapid and reliable method, thin layer chromatography (TLC) fingerprint, has been developed in order to identify, authenticate and differentiate these three herbs through fingerprint profile of chemical compounds. TLC fingerprints of the three herbs were obtained by visualization of separate zones with visible and UV (254 and 366 nm) light. The TLC fingerprint pattern is different each other and showed a specific marker zones respectively. Therefore, TLC fingerprint can be utilized for identification, authentication and differentiation method in quality control of the three herbs tested.

Studies were carried out on the leaves of Cassia alata. Parahydroxy benzoic acid was isolated from the leaves of Cassia alata with the help of column and thin layer chromatography using a gradient of organic solvents with increasing polarity. The compound was characterized on the basis of UV, IR, 1H-NMR and Mass spectrometry. Bangladesh J. Sci. Ind. Res. 41(1-2), 89-92, 2006

The aim of the work is to develop preparative methods for the synthesis of 2-((5-(2,4- and 3,4-dimethoxyphenyl)-3H-1,2,4-triazole-3-yl)thio)acetic acids, to study the esterification reaction in this regard, to study physical and chemical properties of the obtained substances, and to predict their toxicity. Materials and methods. Compounds were synthesized using reagents and solvents qualified as “ch.p.”. The IUPAC nomenclature as supplemented was used during the preparation. The melting temperature was determined with the capillary method according to HFC (2.2.14) on the device PTP (M). Elemental analysis was determined with the ELEMENTAR vario EL cube analyzer (manufactured in Germany) (standard – sulfonamide). IR spectra were recorded using spectrophotometer Specord M-80 (manufactured in Germany) within the range of 4000–500 cm-1 (scanning was performed under the following conditions: slot program 3.0, time constant – τ = 3 s, scanning time 34 min, samples were analyzed in the form of tablets with potassium bromide). 1H NMR spectra were recorded using Varian VXR-300 spectrophotometer (manufactured in the USA), dimethyl sulfoxide-D6 solvent, and tetramethylsilane was used as an internal standard. The spectra were decoded using the computer program ADVASP 1.43. Thin layer chromatography was performed using Sorbfil plates (analytical, size 10 × 15 cm, base: polymer substrate, sorbent: silica gel STX-1A, grain: 5–17 μm, layer thickness: 110 m combination – silicazole). Results. The synthesis of new 2-((5-(2,4- and 3,4-dimethoxyphenyl)-3H-1,2,4-triazole-3-yl)thio)acetic acids was carried out. These products became a basis for synthesis of a number of relevant esters. Physical and chemical properties were investigated for the synthesized compounds. The structure of the obtained substances was confirmed by elemental analysis, IR-spectroscopy, 1H NMR-spectrometry, and their individuality were established by thin-layer chromatography. Computer GUSAR-online prediction of acute toxicity of 2-((5-(2,4- and 3,4-dimethoxyphenyl)-3H-1,2,4-triazole-3-yl)thio)acetic acids and their esters was performed. Conclusions. Preparative methods for the synthesis of 2-((5-(2,4- and 3,4-dimethoxyphenyl)-3H-1,2,4-triazole-3-yl)thio)acetic acids have been developed, for which esterification reactions have been studied. Thus, physical and chemical properties of the received substances were investigated, and indicators of their toxicity were predicted.
