A protocol for the in vitro establishment of two Sicilian genotypes of mulberry has been set up. Multiple shoots were initiated and plantlets were produced from buds collected from mature trees of Morus alba L. and Morus nigra L., grown in the field. The influence of two explanting times (September and December) of buds on the in vitro response has been observed. The percentage of sprouting aft...

Four new 2-arylbenzofuran derivatives, moracins V-Y (1-4), together with two known compounds, moracin N (5) and moracin P (6), were isolated from the leaves of Morus alba L. Their structures were elucidated by spectroscopic analysis. Moracins X (3) and Y (4) represent unusual substituted group compared with 2-arylbenzofuran derivatives, which were isolated from the genus Morus. Compounds 2-5 we...

In this study, leaves of three indigenous varieties of Mulberry namely, Morus alba L., Morus nigra L. and Morus rubra L. were investigated for their antioxidant potential and their proximate composition was determined. The yields of 80% methanolic extracts ranged between 8.28-13.89%. The contents of total phenolics (TPC), total flavonoids (TFC) and ascorbic acid (AA) ranged between 16.21-24.37 ...

Fractionation of the ethanolic extract of the stem bark of Morus yunanensis resulted in the isolation of a new Diels-Alder type adduct and two new flavones, named yunanensin A (1), yunanensol A (2) and yunanensol B (3), respectively, together with a known flavone (4). Their structures were determined on the basis of spectroscopic analysis and chemical methods. Among them, compound 1 showed mode...

Morus alba L. is an important tree species planted widely in China because of its economic value. In this report, we investigated the influence of two arbuscular mycorrhizal fungal (AMF) species, Glomus mosseae and Glomus intraradices, alone and together, on the growth of M. alba L. seedlings under greenhouse conditions. The growth parameters and physiological performance of M. alba L. seedling...

Background & Aim: Applications of synthetic antioxidant in food have side effects. In present study, the antioxidant potential of Morus alba leaves, as natural antioxidant, was screened with cupric ion reducing assay (CUPRAC assay) and inhibition of lipid peroxidation. The aim of this study was to determine the total antioxidant activity of Morus alba leaves. Martial & Method...

Phenolic compounds were extracted from the fruits of Morus nigra and Morus alba using methanol and acetone. The sugar-free extracts (SFEs) were prepared using Amberlite XAD-16 column chromatography. All of the SFEs exhibited antioxidant potential as determined by ABTS (0.75-1.25 mmol Trolox/g), DPPH (2,2-diphenyl-1-picrylhydrazyl) (EC(50) from 48 μg/mL to 79 μg/mL), and reducing power assays. H...
