This study aimed to investigate the potential use of anthocyanin Berberis crataegina DC. as a natural food coloring agent in industry. For this aim, ultrasound-assisted extraction (UAE) method was performed extract The effect ultrasound power (X1: 20-100%), temperature (X2: 20-60 °C), and time (X3: 10-20 min) on TPC TAC extracts were examined optimized by applying Box–Behnken experimental desig...

Bunga telang ( Clitoria ternatea ) merupakan jenis tanaman di Indonesia yang sedang dikembangkan manfaat kandungan senyawa antosianinnya sebagai antioksidan. Proses ekstraksi untuk mendapatkan antosianin dari ekstrak bunga membutuhkan beberapa variasi segi penggunaan pelarutnya agar hasil optimal. Penelitian ini bertujuan mempelajari pengaruh variabel lama perendaman, konsentrasi, dan pelarut t...

A beta-glucosidase (torvosidase) was purified to homogeneity from the young leaves of Solanum torvum. The enzyme was highly specific for cleavage of the glucose unit attached to the C-26 hydroxyl of furostanol glycosides from the same plant, namely torvosides A and H. Purified torvosidase is a monomeric glycoprotein, with a native molecular weight of 87 kDa by gel filtration and a pI of 8.8 by ...

Bioactive potential of apigenin derivative apigenin-7-O-glucoside related to its antifungal activity on Candida spp. and cytotoxic effect on colon cancer cells was studied and compared with bioactive potential of apigenin. Antifungal activity was tested on 14 different isolates of Candida spp. using membrane permeability assay, measuring inhibition of reactive oxidative species and inhibition o...

The Fusarium metabolite culmorin (1) is receiving increased attention as an "emerging mycotoxin". It co-occurs with trichothecene mycotoxins and potentially influences their toxicity. Its ecological role and fate in plants is unknown. We synthesized sulfated and glucosylated culmorin conjugates as potential metabolites, which are expected to be formed in planta, and used them as reference compo...

passiflora species were known by their anticonvulsant, anxiolytic and sedative activities. the aim of this study was to investigate the chemical composition of the most active leaf extract of passiflora caerulea l. grown in egypt. the ethanolic extract of the leaves exhibited higher activity than aqueous extract as anticonvulsant (63% potency relative to carbamazepine), analgesic (70% potency r...

The first reaction in the metabolism of cellobiose in Aerobad er aerogenes was shown to be adenosine 5’-triphosphatedependent phosphorylation at C-6 of the nonreducing ring to yield 6-0-phosphoryl-O-D-glucopyranosyl-(1 + 4)-D-glucase (cellobiose monophosphate). The inducible fl-glucoside kinase that catalyzes the reaction was partially purified and characterized. In addition to cellobiose, the ...

In this study, some quality changes in the optimally thermosonicated (59°C-455 J g-1) cloudy strawberry nectar during storage were evaluated and modelled. The of pH (3.40-3.78), residual polyphenol oxidase-(PPO) activity (24%-11%), total phenolic-(TP) content (688.7-543.2 mg L-1), monomeric anthocyanin-(TMA) (142.5-84.4 anthocyanin, colorless phenolic compounds analyzed three months at 4°C. sig...

The aim of the study was to develop an alternative capillary zone electrophoresis (CZE) for simultaneous determination of phillyrin (1), phillygenin (2), epipinoresinol-4-O-β-glucoside (3), pinoresinol-4-O-β-glucoside (4), lariciresinol (5), pinoresinol (6), isolariciresinol (7) and vladinol D (8) in Forsythia suspensa. The structural types of lignans 1-8 could be attributed to bisepoxylignans ...
