![]() The taxon was then renamed “ Camellia” and subsequently “ Camellia chrysantha” ( Tuyuma, 1975). Camellia with deep yellow blossoms is also referred to as “golden camellia” and was discovered in Guangxi, China, in 1965 by Hu, who named it Theopsis chrysantha ( Hu, 1965). Additionally, they have less yellow blossoms, making them the most sought-after variation of this plant’s flower. ![]() Their flowers are usually red, purple, pink, or white. They are ubiquitous in China and southeastern and eastern Asia, where over 80% of these species are present ( Vijayan et al., 2009). It consists of nearly 200 known species and is widely dispersed throughout China. nitidissima and discriminate adulterated samples of C.nitidissima flower.Ĭamellia, also known as “cha-hua” in Chinese, is the largest genus of flowering plants in the Theaceae family. Combining an infrared spectroscopic method with a chemometric approach proved that it is possible to differentiate distinct sections of C. In addition, PCA-class and OPLS-DA obtained scores of 27/32 and 26/32, respectively, for detecting adulterated and other TCM reference flower samples from C. In addition, the RMSEE, RMSEP, and RMSECV values for the OPLS-DA model were low, and the model’s sensitivity, accuracy, and specificity were all 100%, showing that it is the excellent one. The PCA-class model’s sensitivity, accuracy, and specificity were all >94%, indicating that PCA-class is the good model. nitidissima were well separated and discriminated by PCA and OPLS-DA. The FT-IR and SD-IR spectra of the samples were subjected to principal component analysis (PCA), PCA-class, and orthogonal partial least square discriminant analysis (OPLS-DA) for classification and discrimination studies. nitidissima were well distinguished using Fourier transform infrared spectroscopy (FT-IR), second-derivative infrared (SD-IR) spectra, and two-dimensional correlation infrared (2D-IR) spectra. nitidissima’s flowers, leaves, and seeds. This study used an integrated tri-step infrared spectroscopy method and a chemometric approach to distinguish C. However, unethical sellers adulterated the flower with other parts of Camellia nitidissima in their product. Due to its diverse pharmacological properties, it can be used to treat various diseases. Chi is a golden camellia recognized in Chinese herbology and widely used as tea and essential oil in Chinese communities. ![]()
