Objective: The present study evaluates purification, characterization of anthocyanin from in vitro culture of teak and its antioxidant potential.Methods: Anthocyanin was extracted from in vitro culture, purified by using amber lite XAD column and fractionated by Liquid chromatography mass spectrometry (LC-MS/MS). Various antioxidant assays were carried such as 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH), 2,2'-azino-bis-3-ethyl-benzothiazoline-6-sulphonic acid (ABTS), Oxygen radical absorbance capacity (ORAC), Nitric oxide (NO) and Hydrogen peroxide (H2O2).Results: Liquid chromatography mass spectrometry (LC-MS/MS) revealed the major fraction as cyanidin 3-(2-xylosyl-rutinoside) with unknown peaks. The amount of anthocyanin was 15.23 mg/g monomeric anthocyanin. Further, the potential antioxidant capacity of the teak anthocyanin was comparable to common vegetables and fruits. Similarly, high correlations of anthocyanin with antioxidant activity, such as oxygen radical absorbance capacity (ORAC), 2,2'-azino-bis-3-ethyl-benzothiazoline-6-sulphonic acid (ABTS), and 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) (r = 0.95, 0.93, and 0.80) were found.Conclusion: The high anthocyanins content and potential antioxidant activity suggests that teak anthocyanin may be applied in the food industry as a good source of natural pigments

Lingzhi mushroom is widely used as an alternative treatment to reduce blood pressure and blood sugar levels, to maximize the potential of the Lingzhi fungus antioxidant tests are carried out. This study aims to determine the potential antioxidant activity of water extract and 70% ethanol extract of Lingzhi mushroom with maceration extraction time variation and identification of compounds with Liquid Chromatography Mass Spectrometry (LC-MS). This research begins with the determination of fresh lingzhi mushrooms then made simplicia and extracted by maceration with time variation with soaking time of 24 hours, 48 hours and 72 hours each with 2 solvents namely water and 70% ethanol. The extract was tested by phytochemistry followed by testing the antioxidant activity of Lingzhi mushroom extract (ganoderma lucidum) by DPPH method. Then the compounds were identified by Liquid Chromatography-Mass Spectrometry (LC-MS). Based on the results of research that maceration for 1 hour (1 day) Lingzhi mushroom with 70% ethanol extraction has the potential as an antioxidant with an IC50 value of 94.83 ppm. The results of identification with LC-MS in 70% ethanol extract as a compound that has potential as an antioxidant are Bisphenol M compounds, and 1- - [[2- (3,4-Dimethoxyphenyl) amino]} -3-methyl-2-octylpyrido [1 , 2-a] benzimidazole-4-carbonitrile.

Liquid chromatography-mass spectrometry (LC-MS)-based untargeted metabolomics implies that annotated metabolites can serve as potential markers of the associated bioactivities of plant extracts. Firstly, we selected Aphananthe aspera and Zelkova serrata (Family: Ulmaceae) from 16 Korean plant species based on their distinct principal component analysis (PCA) patterns in LC-MS datasets and antioxidant activity assays. Further, we chose 40% solid-phase extraction (SPE) extracts of the two species displaying the highest antioxidant activities coupled with distinct PCA patterns. Examining the metabolite compositions of the 40% SPE extracts, we observed relatively higher abundances of quercetin, kaempferol, and isorhamnetin O-glucosides for A. aspera, whereas quercetin, isorhamnetin O-glucuronides, and procyanidin dimer were relatively higher in Z. serrata. These metabolites were clearly distinguished in pathway map and displayed strong positive correlations with antioxidant activity. Further, we performed preparative high-performance liquid chromatography (prep-HPLC) analysis coupled with the 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) assay to validate their functional correlations. As a result, quercetin O-sophoroside was determined as the main antioxidant in A. aspera, while isorhamnetin O-glucuronide and procyanidin dimer were the primary antioxidants in Z. serrata. The current study suggests that the LC-MS-based untargeted metabolomics strategy can be used to illuminate subtle metabolic disparities as well as compounds associated with bioactivities.
