One anthocyanin and four flavonols were detected from the petals of Hibiscus hamabo, H. tiliaceus and H. glaber. They were identified as cyanidin 3-0- sambubioside, gossypetin 3-O-glucuronide-8-O-glucoside, quercetin 7-O-rutinoside, gossypetin 3-O-glucoside and gossypetin 8-O-glucuronide by UV
Titanbicus (TB), a hybrid of Hibiscus moscheutos × H. coccineus (Medic.) Walt., has potential to be used as an edible flower. In this study, proximate nutritional content, anthocyanin content, total polyphenol content (TPC), and antioxidant activities in vitro and in vivo were investigated. Three
