Potential of Gynura procumbens leaves as source of flavonoid-enriched fractions with enhanced antioxidant capacity

Antioxidant and antimicrobial activity of a mangrove plant Avicennia marina (Forsk.)

“…Studies of different researchers revealed that there was a direct correlation between TPC and antioxidant activity [24] or TFC and antioxidant activity of plant extracts [25]. In the present study, the maximum TPC was in polar solvent extracts as also reported by Ammar et al [26] and Chanda et al [27] and the maximum TFC was in ethyl acetate extracts.…”

“…Furthermore, flavonoids are also well known to have anti-oxidant and anticancer activities. A strong positive correlation between antioxidant activity and total flavonoid content was reported in Gynura procumbens (Kaewseejan, Sutthikhum, & Siriamornpun, 2015). A flavonoid quercetin (quercetin 3-β-D-glucoside) isolated from Satureja montana contained antioxidant activity (López-Cobo, Gómez-Caravaca, Švarc-Gajić, Segura-Carretero, & Fernández-Gutiérrez, 2014), whereas quercetin (quercetin-3-O-α-L-rhamnopyranoside) obtained from Toona sinensis was reported to be an antioxidant with anticancer activities (Zhang et al, 2014).…”

Gynura procumbens: An Overview of the Biological Activities

“…In a comparative study, the ethanol extract of G. procumbens exhibited the highest percentage of DPPH inhibition (52.81%) among different types of plant extracts that were tested (Maw et al, 2011). Meanwhile, the reductive ability of G. procumbens extract has also been tested by using ferric reducing assay which has further proven the antioxidant capacity possessed by this plant (Kaewseejan et al, 2015). …”

“…The plant leaf is commonly consumed and scientifically it has been shown to be safe for consumption (Rosidah et al, 2008). In Malaysia, the fresh leaves of G. procumbens are commonly eaten raw and in Thailand, the leaves are also used for cooking (Kaewseejan et al, 2015). In Malay, G. procumbens is called Sambung Nyawa which means “prolongation of life” whereas in Chinese, it is called Bai Bing Cao which means “100 ailments” (Bodeker et al, 2009).…”
