“…C. odorata is a species of the genus Chromolaena which is one of the largest genera of the family Eupatorieae (Asteraceae) [8]. In Indonesia, C. odorata, known as sungga-sungga, was collected from Ambon, Maluku, East Indonesia.…”

“…Accordingly, both hydroxyl and methoxy substituents were assigned as 3'-hydroxy [9, 13] and 8-methoxy [14] at C-3' and C-8. Interestingly, although more than 79 flavonoid compounds have been isolated from the genus Chromolaena [8], the methoxy substituent at C-6' has not been reported yet before. Accordingly, the compound of (1) is a new flavanone named odoratenin (1) as in Figure 5(1).…”

“…(2017), they reported that about 40 flavonoids have been identified from this genus. One of species from this genus, C. hirsuta , has been reported to contain quercetin and kaempferol derivatives which belong to flavonoids group [8]. Some researchers also reported that C. odorata contains the flavonoid compounds [9–15].…”

Chromolaena odorata L. (Asteraceae) is one of the tropical plants which is widely used as traditional medicines for diabetes and soft tissue wounds treatment in some regions in East Indonesia. The present study was aimed at determining the bioactive compounds of C. odorata leaves. The methanol and ethyl acetate extracts of C. odorata leaves have the inhibitory activity against 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and 2,2’-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals as well as α-glucosidase rat intestine enzyme. A new flavanone was isolated from the methanol extract and elucidated as 5,3’-dihydroxy-7,6’-dimethoxyflavanone or, namely, odoratenin (1) together with two known compounds: isosakuranetin (2) and subscandenin (3). The antioxidant activity of odoratenin (1) exhibited very potent ABTS radical inhibitory activity with IC50 value of 23.74 μM which is lower than that of trolox (IC50 31.32 μM) as a positive control. The result showed that a new flavanone, odoratenin (1), should be potential as an antioxidant source.

“…In addition, it is well revealed that the flavonoid data on flowering plants are often of value for resolving the evolutionary relationships among the taxa (Markham et al 1970). For instance, flavonoid data can be used as a taxonomic features of the genus Chromolaena, and the chemotaxonomic significance of ISSN 2412-1908 http://journal.asu.ru/biol these compounds was useful for resolving the infra-generic complexity of the genus (de Oliveira et al 2017). Furthermore, Braunberger et al (2015) have reported that flavonoids were used as chemotaxonomic characteristics in Drosera for the species classification in sections and for the improvement of infra-generic taxonomy in this genus.…”

The genus Cotoneaster consists of unarmed shrubs that naturally distributed in north parts of Iran. It is a problematic genus, and there are many discussions about its species number in Iran as well the World. Recently, M Khatamsaz has been listed 19 species of it in Iran. In the current research, we studied leaf flavonoid composition of seven Cotoneaster species from Iran. These species were harvested from the northern provinces of the country and their leaf ethanolic extracts were subjected to HPLC, for detection the types and amounts of their flavonoid compounds. We identified four flavonoid compounds: rutin, myricetin, quercetin, and kaempferol. The concentration of these flavonoids differed between the species, moreover amount of each flavonoid also varied among the studied species. All of them were registered in the studied species, except for myricetin, which was not observed in C. nummularius. The highest amount of flavonoids were detected in C. nummularius, while C. discolor had the lowest one. The evaluated species divided into four distinct group in UPGMA tree. According to CA-Joined plot, each group was characterized by species amount of flavonoid(s). All of evaluated species belonged to the same section of the genus, therefore our findings revealed that the flavonoid data were useful at sectional level for identification of the species.

“…loena odorata leaf as herbal remedies for inflammation and infection. Cromaloena odorata leaf has been reported to contain phenols, flavonoids, saponins, terpenoids, tannins and steroids (Benjamin, 2015;Putri, & Fatmawati, S. 2019;De Oliveira, Bernardi, & Balbinot, 2017). Pharmacological activities of Cromaloena odorata leaf is in a wide range, from antifungal (Naidoo, Coopoosamy, & Naidoo, 2011), antioxidant (Handayany, Umar, & Ismail, 2018), Anti-plasmodial (Ezenyi, Salawu, Kulkarni, & Emeje, 2014), anti-infammatory (Hanh, Hang, Van Minh, & Dat, 2011), and antibacterial (Marianne, Lesatri, Sukandar, Kurniati, & Nasution, 2014;Atindehou, Lagnika, & Guerold, 2013) properties.…”

The Cromaloena odorata (COE) contains phenols, flavonoids, tannins, alkaloids, saponins, steroids that possess diverse therapeutic effects. However, COE has poor solubility in water and poor absorbtion in the body. Incorporation of COE in nanofiber system is a promising way to increase CEO solubility. One of the method to produce nanofiber is electrospinning. The electrospinning process there are three of the most important process parameters are applied flowrate, voltage and TCD. In this study we developed optimized condition for electrospinning process of polyvinyl alcohol (PVA)/CEO and their characterization. The Scanning electron microscopy (SEM) analysis showed that modification of flowrate and TCD did not affect the morphology of PVA and COE fiber. However fiber diameter decreased when lower flowrate, higher voltage was applied, and TCD. Fourier Transform Infrared (FTIR) study was conducted to identify possible intermolecular interaction between PVA/COE that has potential application as antimicrobial wound dressing.
