“…In this research, meristem can be seen to be better than basal parts in producing higher antioxidant content. Similar indings can be seen in a study Jiménez-Aspee et al (2018) that stated the meristem part has higher antioxidant activity compared to other parts of plants.…”

Black ginger or is one useful medicinal plant that urges the need to be cultivated widely. This plant has some previous studies about their rhizomes and callus growth optimization, but their total content and antioxidant activities are not very . This study aims to study the total content and antioxidant activities of callus of K.. This study is to determine the type and concentration of hormone that give the best effect on the growth of callus in culture from different parts (, and basal part) of K.. Different concentrations were tested with medium 2,4-dichlorophenoxyacetic acid (2,4-D) and acid (NAA) in callus cultivation. The highest total content tested in callus is one with 10.00 mg/L 2,4-D from the part of the plant. The highest antioxidant activity is from the part of the plant with 5.00 mg/L 2,4-D.

“…Compounds 2 and 5 showed a common [M − H] − molecular ion at m / z 370.9 amu, with MS 2 fragment ions at m / z 209 and 191 amu, indicating the presence of a hexaric acid core (glucaric, mannaric, or galactaric acids) [30]. The neutral loss of 162 amu agreed with a caffeoyl moiety.…”

“…Compounds 30 and 31 were assigned as myricetin hexosides by the neutral loss of 162 amu, while compound 34 was identified as myricetin rutinoside by the neutral loss of 308 amu. In addition, the presence of dimethylmyricetin hexoside (siringetin hexoside, 61 ) was suggested by the MS 2 fragment ion at m / z 344.6 amu [30].…”

The Argentinean Patagonia berries Berberis microphylla, Berberis darwinii, and Fragaria chiloensis ssp. chiloensis f. patagonica were investigated for their polyphenol content and composition by means of liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry. The in vitro antioxidant activity and inhibition of metabolic syndrome-associated enzymes (α-glucosidase, α-amylase, and lipase) of the fruit extracts was assessed. The most complex polyphenol profile was found in the Berberis samples, with 10 anthocyanins, 27 hydroxycinnamic acids, 3 proanthocyanidins, 2 flavan-3-ol, and 22 flavonols. Fragaria presented four anthocyanins, nine ellagitannins, two proanthocyanidin dimers, one flavan-3-ol, and five flavonols. The Berberis samples showed the best antioxidant capacity, while Fragaria displayed better activity against α-glucosidase and lipase. The phenolic content and composition of the Argentinean Patagonia berries was similar to that reported for Chilean samples but with some chemical differences between Eastern (Argentina) and Western (Chile) Patagonia. The data obtained supports the consumption of these berries as sources of beneficial polyphenols.

“…The antioxidant activity of the PEEs was determined by the following assays: discoloration of the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid diammonium salt (ABTS • ) radicals (Trolox equivalent antioxidant capacity, TEAC), the ferric reducing antioxidant power (FRAP) and oxygen radical antioxidant capacity (ORAC) assays. All the methodologies were carried out as previously described (Jiménez-Aspee et al, 2018). Stock solutions of the PEEs were dissolved in MeOH (1-5 mg/ mL, for the DPPH, FRAP and TEAC assays) or phosphate buffer (10-50 µg/mL, for the ORAC assay).…”
