Golden camellia is defined as a species of the Camellia genus with yellow flowers, which have long been used as a medicine, food, and cosmetic in many Asian countries. To date, more than 50 golden camellia species are considered endemic in Vietnam; however, more information is needed about its chemical constituents and biological activity. This work aims to unveil the potential of Camellia tienii Ninh, a golden camellia species, as an herbal beverage by examining the presence and abundance of chemical components in flowers and leaves. A comprehensive strategy has been developed using both liquid and gas chromatography coupled with mass spectrometry. Specifically, LC-MS-based widely targeted analyses were opted to characterize 158 polar metabolites belonging mainly to flavonoids, catechins, and amino acids classes, and an untargeted approach using GC-MS annotated 42 major volatile compounds such as terpenes and fatty acids. The extensive profile revealed by these techniques could help understand the significant discrimination between two organs. C. tienii flowers accumulated more flavonoids, amino acids, and fatty acids, while leaves contain more terpenes, suggesting different pharmacological properties of these materials. Overall, this pipeline can be applied for other Camellia species and valorization of these valuable resources for health benefits purposes.

Golden camellia species are endangered species with great ecological significance and economic value in the section Chrysantha of the genus Camellia of the family Theaceae. Literature shows that more than 50 species of golden camellia have been found all over the world, but the exact number remains undetermined due to the complex phylogenetic background, the non-uniform classification criteria, and the presence of various synonyms and homonyms; and phylogenetic relationships among golden camellia species at the gene level are yet to be disclosed. Therefore, it is necessary to investigate the divergence time and phylogenetic relationships between all golden camellia species at the gene level to improve their classification system and achieve accurate identification of them.

Liupao tea is a postfermented dark tea with hypolipidemic activity. Research on the active substances in Liupao tea has primarily focused on those derived from the tea itself, overlooking the secondary metabolites produced by its predominant fungus, . In this study, CPCC 401251, the predominant strain found in Liupao tea under investigation, was isolated and analyzed.

Background: Camellia nitidissima Chi is a popular ornamental plant because of its golden flowers, which contain flavonoids and carotenoids. To understand the regulatory mechanism of golden color formation, the metabolites of C. nitidissima petals at five different developmental stages were detected, a proteome map of petals was first constructed via tandem mass tag (TMT) analysis, and the accuracy of the sequencing data was validated via parallel reaction monitoring (PRM).
