2 arylbenzofuran/マグワ

Oxidation and enzymatic browning of food can affect nutritional quality, physical and chemical properties, and food safety, emphasizing the utmost importance of discovering new natural antioxidants and anti-browning agents. The present study aimed to characterize the antioxidant and anti-browning

Ten new geranylated 2-arylbenzofuran derivatives, including two monoterpenoid 2-arylbenzofurans (1 and 2), two geranylated 2-arylbenzofuran enantiomers (3a and 3b), and six geranylated 2-arylbenzofurans (4-9), along with four known 2-arylbenzofurans (10-13) were isolated from the root bark of Morus

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

Among the 2-arylbenzofuran derivatives isolated from Morus alba, the farnesylated 2-arylbenzofuran is a rarer constituent. The derivative has been reported to exert anti-obesity effect; however, its inhibitory effect on protein tyrosine phosphatase 1B (PTP1B) has not been investigated. In the

A new 2-arylbenzofuran compound, 5-dehydroxy-moracin U (1), along with 10 known compounds (2-11), were isolated from cell cultures of Morus alba. Their structures were elucidated on the basis of extensive spectroscopic analyses. The anti-inflammatory activity assay of 1-8 showed that 2 and 8

Chromatographic separation of root extracts of Morus alba and M. nigra led to the identification of the 2-arylbenzofurans moracin C (1), mulberrofuran Y (2), and mulberrofuran H (3), and the prenylated flavonoids kuwanon E (4), kuwanon C (5), sanggenon H (6), cudraflavone B (7), and morusinol (8),

Two new Diels-Alder adducts, albasins A and B (1 and 2), one new isoprenylated 2-arylbenzofuran, albasin C (3), one new isoprenylated flavone, albasin D (4), together with sixteen known phenolic compounds, were isolated from the root bark of Morus alba. Their structures were elucidated by extensive

Chemical investigation of the root bark of Morus alba led to the isolation of a new flavone, dioxycudraflavone A (1) and a new 2-arylbenzofuran, 5-hydroxyethyl moracin M (2), together with seven known compounds namely sanggenon V (3), morusin (4), morusignin L (5), licoflavone C (6), moracin C (7),

In this paper, quadruple high-resolution α-glucosidase/α-amylase/PTP1B/radical scavenging profiling combined with HPLC-HRMS-SPE-NMR were used for studying the polypharmacological properties of crude root bark extract of Morus alba L. This species is used as an anti-diabetic principle in many

The hypoglycemic activity of the flavonoids rich fraction of 70% alcohol extract of the Egyptian Morus alba root bark (MRBF-3) was evaluated after its oral administration to streptozotocin-induced diabetic rats. Diabetes was induced by injection of 60 mg kg(-1) i.p. The administration of MRBF-3 to

A new arylbenzofuran, 3',5'-dihydroxy-6-methoxy-7-prenyl-2-arylbenzofuran (1), and 25 known compounds, including moracin R (2), moracin C (3), moracin O (4), moracin P (5), artoindonesianin O (6), moracin D (7), alabafuran A (8), mulberrofuran L (9), mulberrofuran Y (10), kuwanon A (11), kuwanon C

Detailed phytochemical investigation from the root bark of Morus alba resulted in the isolation of eleven new compounds, including seven 2-arylbenzofuran derivatives (morusalfurans A-G), three flavonoids (morusalnols A-C), and one geranylated stilbene (morusibene A), as well as 22 known compounds.

Two new 2-arylbenzofuran derivatives, moracinfurol A and B (1-2), and ten known compounds (3-12) were isolated from the leaves of Morus alba. Their structures were determined on the basis of spectroscopic analysis including 1D, 2D NMR and HR-ESI-MS. All of the 2-arylbenzofuran derivatives were
