Genetic differentiation and antioxidant activities ofBouea macrophyllaGriffith in Nakhon Nayok province

Abstract

Genetic differentiation and antioxidant activities in ethanolic extracts from leaves of Bouea macrophylla Griffith were determined. The result revealed genetic differentiation among sour ma-praang, ma-yong and sweet ma-praang of B. macrophylla Griffith (φ PT =0.772, p-value=0.000). In addition, high genetic diversities were found in sour ma-praang and sweet ma-praang populations (P: 51.4 and 57.1 %; He: 0.1900.035 and 0.2240.036, respectively), but low genetic diversity was found in ma-yong population (P: 8.6 %; He: 0.0350.021). Total phenolic contents of sour ma-praang, ma-yong and sweet ma-praang were estimated as 680.51±89.81, 701.03±59.89 and 530.85±41.23 mg gallic acid/g extract, respectively. Free radical scavenging activities of sour mapraang, ma-yong and sweet ma-praang were found (1/EC50= 4.17, 1.43 and 1.37, respectively) corresponding with metalchelating activities (1/EC50=0.83, 0.65 and 0.17, respectively). Therefore, the obtained data may be applied to cultivation and utilization of their leaves as source of natural phenolics and antioxidants.

Maprang “Bouea macrophylla Griffith” seeds: proximate composition, HPLC fingerprint, and antioxidation, anticancer and antimicrobial properties of ethanolic seed extracts

“…This is higher than that of the ripe fruit that were in the range of 0.012–0.020 mg GAE/mg MPFEs. Our results are similar to that of Thummajitsakul and Silprasit who reported that the TPC 95% etanolic leave extracts ranged from high to low levels, with mayong chid being the highest at 0.701 mg GAE/mg MPLEs, maprang prieyo at 0.680 mg GAE/mg MPLEs, and maprang wan at 0.531 mg GAE/mg MPLEs [28]. Andina and Musfirah found that the TPC was 0.137 mg GAE/mg MPCEs and 0.068 mg GAE/mg MPLEs for the ethanolic extraction of Ramania (Maprang) cortex and leaves, respectively [29].…”

“…Andina and Musfirah found that the ethanolic extraction of the maprang cortex and leaves scavenged DPPH radicals by IC 50 at 20.03 μg/mL and 55.83 μg/mL, respectively [29]. Thummajitsakul and Silprasit reported that the ethanolic extracts obtained from the leaves of three maprang varities, maprang prieyo, mayong chid, and maprang wan, exhibited 50% ABTS ·+ scavenging activity with (EC 50 ) being 0.24 ± 0.08, 0.73 ± 0.07, and 0.70 ± 0.06, respectively [28]. In terms of the influence of the extraction solvents on antioxidant activity, Onivogui et al.…”

Potential Antimicrobial and Anticancer Activities of an Ethanol Extract from Bouea macrophylla

“…Flavonoids possess scavenging or chelating antioxidant activity [24,25]. A previous study also revealed that the leaves of B. macrophylla had potent antioxidant activity using the ABTS free-radical scavenging and metal chelating assays [7]. In this study, the results of two assays-FRAP (total electron transfer-based) and DPPH (hydrogen atom transfer-based)-revealed that the plant extract exhibited strong antioxidant activity.…”

“…The antibacterial activity determined for various concentrations of the B. macrophylla extract has not been reported previously [5,7,21]. This study investigates for the first time the antimicrobial properties of a B. macrophylla extract in vitro.…”

Total phenolic content, quercetin, and antioxidant activity of gandaria (Bouea Macrophylla Griff.) leaf extract at two stages of maturity

“…Since it is more abundant, less expensive, and easier to harvest without seasonal limitation. Various active compounds in mapraang/gandaria have been confirmed by Thummajitsakul and Silprasit (2017). In Indonesia, Andina and Musfirah (2017) have found several active compounds of ramania/gandaria leaf cortex extract from South Kalimantan.…”
