Euphorbia nivulia (EN) one of the members of Euphorbiaceae family, is a medicinal plant of Cholistan Desert (Punjab, Pakistan) that is traditionally used for a number of diseases. The plant is enriched with many phyto-constituents including flavonoids, triterpenes and polyphenols. In present study, crude extract as well as various fractions were assessed for phytochemical analysis, HPLC profiling, radical scavenging property and total phenolic and flavonoid contents. Hydro-alcoholic (70%) crude extract of EN was subjected to fractionation using different solvents including n-hexane, chloroform, butanol and aqueous. After performing the phytochemical screening and HPLC profiling, antioxidant activity was estimated by using DPPH and FRAP assays. Total flavonoid and phenolic contents were also estimated. HPLC analysis confirmed the presence of flavonoids and polyphenols like quercitin, gallic acid, caffeic acid, vanillic acid, benzoic acid, chlorogenic acid, syringic acid and ferulic acid in crude extract as well as butanol and aqueous fractions. Results revealed that butanol fraction showed maximum phenolic (143.26±2.65 mg/g GA/g) and crude extract showed maximum flavonoid (69.80±1.212 mg/g Q) contents. Maximum antioxidant potential was displaced by butanol fraction which was IC50=0.04±0.02 by DPPH and 1193.77±12.4 μmol TE/ml by FRAP respectively. Current study is the first information about the HPLC profiling of phenolic compounds in EN and its antioxidant potential that could be a step forward towards ethno-pharmacological based phyto-medicine.

Sideritis niveotomentosa Hub. -Mor. is a local endemic species belonging to the Lamiaceae family. In this study, GC/MS analysis, total antioxidant capacity and anticancer effects of different extracts obtained from S. niveotomentosa were investigated comparatively. Total phenolic contents of extracts were determined by the Folin–Ciocalteu method, total flavonoid contents by aluminum chloride method, and also the free radical scavenging activities of the extracts by DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) assay. The cytotoxic effect of the extracts was studied via MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) assay on DLD1, HL60 and ARH77 cell lines. Pro-apoptotic gene expression levels were also tested in the most sensitive cell line ARH77 by Real-Time PCR. The expression levels of 4 pro-apoptotic genes, APAF, BAX, CASP3, and HRK were found to be upregulated in ARH77 cells that were treated extracts. Results showed that methanolic extracts contain more phenolic content than acetone extracts, consistent with DPPH results. As a result, Sideritis niveotomentosa extracts, especially methanolic extracts, are rich in phenolic content and have a strong radical scavenging effect. In addition, the extracts showed selective effects on cell lines. This study is pioneering in terms of future studies, and the findings provide hope for future experimentation.

ABSTRACT Allophylus edulis and Cupania vernalis (Sapindaceae) are Brazilian native trees used as medicinal plants for the treatment of respiratory, digestive, circulatory, and skin diseases. Ubiquitously distributed in the Brazilian territory, these species are indicated for mixed plantations aimed at the recovery of degraded ecosystems. In this study, the total phenolic content (TPC) and total flavonoid content (TFC), and the antioxidant activity of extracts and fractions obtained from A. edulis and C. vernalis leaves were assessed. The TPC and TFC was determined spectrophotometrically. Antioxidant activity was evaluated through radical scavenging activity of 2,2-diphenyl-1-picrylhydrazyl (DPPH). The extracts were obtained by two methods: maceration (method 1) and Soxhlet (method 2). Solvents of increasing polarity (hexane, dichloromethane, ethyl acetate, and n-butanol) were used to obtained the fractions. The results showed that the ethyl acetate fraction from A. edulis, obtained from the maceration method, had the highest TPC (442.0 ± 18.2 mg GAE g-1) and TFC (58.1 ± 0.4 mg RUE g-1), and antioxidant activity (EC50 = 43.6 ± 2.6 µg mL-1). By C. vernalis, superior results were obtained with the n-butanol fraction (TPC = 126.1 ± 5.8 mg GAE g-1, TFC = 37.7 ± 0.6 mg RUE g-1). The highest antioxidant potential was found in the crude hydroalcoholic extract (EC50 = 816.1 ± 50.9 µg mL-1) and butanol fraction (1,156.4 ± 3.8 µg mL-1). The results of this study show that the fractions obtained by maceration and liquid-liquid partition with more polar solvents (ethyl acetate and n-butanol) are the richest in TPC and TFC, and presented the greater antioxidant activity. Comparing the two plants, A. edulis showed the best results, with a high content of TPC, TFC, and antioxidant potential, and therefore may be used to treat diseases related to oxidative stress.

Curculigo is a potent plant with a variety of traditional uses, such as anti-oxidant, anti-diabetic, anti-tumor, anti-bacterial, anti-cancer, anti-osteoporosis, and wound-healing. The comprehensive profiling of the Curculigolatifolia metabolome was carried out by generating a molecular network (MN) from Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) data to profile the methanol extract and correlating them with their antioxidant (2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH), total phenolic contents (TPC), and β-carotene) and antimicrobial (disk-diffusion agar method, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC)) properties. The antioxidant capacity was observed to be significantly higher in the rhizome crude extract, with 18.10 ± 0.91 µg/mL DPPH activity, and a β-carotene bleaching result of 35.20%. For the antimicrobial activity, the leaf crude extract exhibited a strong Staphylococcus aureus and Salmonella choleraesuis (8–15 ± 3.0 mm) inhibition in the disk-diffusion agar. The leaf extract also exhibited maximum antibacterial activity against S. aureus (MIC = ±0.25 mg/mL, MBC = ±0.25 mg/mL) and S. choleraesuis (MIC = ±0.25 mg/mL, MBC = ±0.25 mg/mL). LC-MS/MS analysis and MN revealed norlignans and phenolic glycosides as major metabolites in the rhizome and leaf extracts of the negative mode (M − H)−. Fourteen known compounds were identified, and three unknown compounds were putatively identified in the rhizome extract, while ten known compounds and six unknown compounds were putatively identified in the leaf extract.

  The Himalayan region is rich in flowering plants diversity, including medicinal and wild edible plants. These plants possess variety of therapeutically important compounds, like alkaloids, flavonoids, phenolics, saponins, steroids, tannins and terpenoids in different parts. Presence of significant amount of these compounds makes a species valuable to be used as super foods or medicines. Furthermore, plant extracts especially those of fruits are basically attributed with natural antioxidants, either in form of vitamins or color-inducing pigments, which have become the target to replace the synthetic antioxidants. In this regard, fruits of Berberis species, one of the popular wild edible fruits of Nepal, are noted for their antioxidant property since time immemorial. The present study was done with an attempt to quantify the antioxidant potential and antibacterial activities of the fruit extracts of four taxa of Berberis (B. angulosa var. angulosa, B. angulosa var. fasciculata, B. aristata and B. asiatica) from Nepal and to correlate the antioxidant potential with various phytochemicals present in the extracts. Methanolic fruit extracts were used to spectrophotometrically quantify total phenolic and flavonoid contents. DPPH free radical scavenging assay and antibacterial assay were carried out in in-vitro condition. Preliminary phytochemical analysis revealed high polyphenol content (52.60 ± 3.73 and 58.07 ± 1.44 mg GAE/g) and better antioxidant property (35.29 ± 3.01 and 29.15 ± 2.01 μg/ml) respectively in B. angulosa var. angulosa and B. angulosa var. fasciculata than in the fruit extracts of B. aristata and B. asiatica. In contrast, fruit extracts of B. asiatica showed the highest total flavonoid content (27.52 ± 0.56 mg QE/g) than did by the extracts of other taxa studied. The fruit extract of B. aristata and B. angulosa var. fasciculata at very high concentration (200 mg/ml) showed maximum zone of inhibition (ZOI) against tested bacterial strains, Staphylococcus aureus and Escherichia coli. In contrast, B. asiatica did not show any ZOI for both of the tested bacterial strains. As fruits are better sources of antioxidant with greater accumulation of flavonoids and phenolics, wild fruits should be equally spaced for their better efficiency as cultivated ones.Botanica Orientalis – Journal of Plant Science (2016) 10: 6–11
