Type II diabetes mellitus (T2DM) is the most common form of diabetes and has become a major health problem across the world. The root bark of Morus alba L. is widely used in Traditional Chinese Medicine for treatment and management of diabetes. The aim of the present study was to evaluate the enzyme
Mulberrofuran G (1) and isomulberrofuran G (2), a pair of isomeric Diels-Alder-type adducts, were isolated from the root bark of Morus alba L. Isomulberrofuran G (2) as a new IIB-type Diels-Alder-type adduct, was elucidated by extensive (1)H, (13)C, and two-dimensional (2D) nuclear magnetic
A new isoprenylated flavonoid, 2S-5,7,2',4'-tetrahydroxy-3',5'-di-(γ,γ-dimethylallyl)flavanone, sanggenol Q (1), along with seven known isoprenylated flavonoids, sanggenol A (2), sanggenol L (3), kuwanon T (4), cyclomorusin (5), sanggenon F (6), sanggenol O (7), and sanggenon N (8), three known
Sanggenol P (1), a new isoprenylated flavonoid, together with nine known ones, cyclomorusin (2), morusin (3), mulberrofuran G (4), sanggenol A (5), sanggenol L (6), sanggenol N (7), cyclomulberrin (8), cyclocommunol (9) and ursolic acid (10) was isolated from Morus alba L. Sanggenol P (1) was
The inhibition of acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and β-site amyloid precursor protein cleaving enzyme 1 (BACE1) plays important roles in prevention and treatment of Alzheimer's disease (AD). Among the individual parts of Morus alba L. including root bark, branches,
In this study, we delineate the human monoamine oxidase (hMAO) inhibitory potential of natural Diels-Alder type adducts, mulberrofuran G (1), kuwanon G (2), and albanol B (3), from Morus alba root bark to characterize their role in Parkinson's disease (PD) and
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),
BACKGROUND
It is valuable to find the potential activity of regulating the excessive mucin secretion by the compounds derived from various medicinal plants. We investigated whether aqueous extract of the root bark of Morus alba L. (AMA), kuwanon E, kuwanon G, mulberrofuran G, and morusin
As part of our continuing research to obtain pharmacologically active compounds from Morus alba L. (Moraceae), four Diels-Alder type adducts (DAs) [morusalbins A-D], one isoprenylated flavonoid [albanin T], together with twenty-one known phenolic compounds were isolated from its root bark. The
Mulberry Diels-Alder-type adducts (MDAAs) are a group of structurally unique natural products biosynthetically derived from the intermolecular [4 + 2] cycloaddition of a dehydroprenylphenol and a chalcone. In the current study, ten MDAAs, including an undescribed one, inethermulberrofuran C, were
Antimicrobial activity of the 18 prenylated flavonoids, which were purified from five different medicinal plants, was evaluated by determination of MIC using the broth microdilution methods against four bacterial and two fungal microorganisms (Candida albicans, Saccaromyces cerevisiae, Escherichia
The phytochemical profiles of Morus nigra roots and twigs were compared by HPLC with those of the old and young twigs of Morus alba which are known to contain oxyresveratrol and mulberroside A as major components. It was found that M. nigra root extract contains some unknown natural products with
