Abstract: Curcuma aromatica Salisb. commonly known as wild turmeric, is a medicinal plant of the family Zingiberaceae widely used in traditional medicine systems for its therapeutic properties andin cosmetic industry due to its skin caring properties. In Hindi it is called as Jangli haldi and as Kasthurimanjal in Malayalam. The plant rhizomes are valued for its plant secondary metabolites like alkaloids, terpenoids, flavonoids, saponins, tannins, phenols, phytosterols, glycosides, volatile oils and curcuminoids. These compounds contribute to the plant’s various therapeutic properties, such as antioxidant, anti-inflammatory, and antimicrobial activities. In herbal market wild turmeric powder of different brands are available targeting on the increased consumer demand for its beauty care usages. This study aimed to perform the quality analysis of Curcuma aromatic powder samples of different brands collected from the herbal market of Kerala using High Performance Thin Layer Chromatographic (HPTLC) tool. HPTLC is a widely employed technique for qualitative analysis and authentication of plant samples. In this study the HPTLC chromatogram of the genuine plant powder samples were compared with that of market samples. The HPTLC profile of the methanol extract of genuine plant material gave a specific fingerprint which can be well differentiated from spurious samples by cross matching. When matched with the profile of Curcuma longa powder sample, it was found that most of the samples are either of turmeric or mixed with turmeric and sold as pure wild turmeric powder. This HPTLC method can be effectively utilized for checking the market samples for ensuring the quality. The study revealed that only18 percent of the market samples tested were pure Curcuma aromatica powder; the rest were spurious.
