ABSTRACT

Hibiscus trionum L. is an annual herbaceous plant belonging to the Malvaceae family. It is native to Central Africa, however, is now naturalized in Europe and Asia including Korea. Here, we report the complete chloroplast genome assembly of H. trionum. The complete chloroplast genome comprises 160,530 bp and is divided into four typical regions: a large single-copy region of 89,272 bp, a pair of inverse repeats of 26,152 bp each, and a small single-copy region of 18,954 bp. A total of 131 genes were identified in this chloroplast, of which 86 were protein-coding, 37 were tRNA, and 8 were rRNA genes. The results of this study will serve as a key reference for further research on Hibiscus speciation.

ABSTRACT

As the national flower of Korea, the Hibiscus syriacus L. (Rose of Sharon) is symbolic in its abundance and is a prominent feature of Korean culture. H. syriacus has played an important role in Korea, not only as an ornamental plant but also as an essential ingredient in folk remedies through its various parts. This study aimed to characterize the nutritional and biochemical composition of each plant unit of H. syriacus "Wonhwa." The units are namely: the petals, leaves, roots, and sprouts from its seeds. According to the results each unit produced, the sprouts had the highest content of amino acids and fatty acids which adhere to the requirements of nutritionally excellent food ingredients. The petals produced high quantities of glucose, sucrose, and fumaric acid, with the highest antioxidant activity among the four units. The main bioactive compounds detected in H. syriacus extracts in the four units were o-coumaric acid, p-coumaric acid, schaftoside, isoschaftoside, apigenin-6-C-glucoside-7-o-glucoside, and kaempferol-3-O-galactoside-7-O-rhamnoside. Overall, the highest number of bioactive compounds, 2 phenolic acids and 22 flavonoids, were identified in the petals. These results suggest the possibility of excellent pharmacological activity in the petals.
