juglanin/juglans regia

A simple and reliable analytical method based on high-performance liquid chromatography (HPLC) coupled with a diode array detector (DAD) was developed for the determination of a novel diarylheptanoid (Juglanin B) from green walnut husks (Juglans regia L.) in rat plasma using rhoiptelol as an

A fast capillary zone electrophoresis (CZE) method for the simultaneous determination of four cyclic diarylheptanoids (rhoiptelol, RH; juglanin A, JA; juglanin B, JB; juglanin C, JC) and an alpha-tetralone derivative (sclerone, SC) in the extract of the green walnut husks (Juglans regia L.) was

By optimizing extraction, separation and analytical conditions, a reliable and accurate high-performance liquid chromatographic (HPLC) method coupled with photodiode array detector (DAD) at room temperature is developed for simultaneous determination of three diarylheptanoids (juglanin A, juglanin

A new diarylheptanoid, juglanin C(1), was isolated from the 80 % methanolic extract of the leaves and twigs of JUGLANS SINENSIS with three known diarylheptanoids, juglanin A(2), juglanin B (3), and (5R)-5-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1(4-hydroxyphenyl)-3-heptanone (4), using

Idiopathic pulmonary fibrosis (IPF), characterized by excessive collagen deposition, is a progressive and typically fatal lung disease without effective therapeutic strategies. Juglanin, as a natural product mainly isolated from green walnut husks of Juglans mandshuric, has various bioactivities,

Fourteen chemical constituents, including 5-hydroxy-4-methoxy-1-tetralone(1), 4,8-dihydroxy-1-tetralone(2), 4,5-dihydroxy-α-tetralone(3), blumenol B(4), dehydrovomifoliol(5), megastigm-5-ene-3,9-diol(6), juglanin B(7), blumenol C(8), loliolide(9), oleracone B(10), syringarsinol(11), pinoresinol(12),

Two new diarylheptanoids, juglanin A (1) and B (2), together with 15 known compounds, were isolated from the extract of the seed husks of walnuts (Juglans regia L.). The structures of 1 and 2 were elucidated by various spectroscopic methods including intensive 2D-NMR techniques, HR-ESI-MS, and X-ray

Breast cancer is one of the most common primary malignant tumors of among women, the long-term survival of which has stagnated in the past decades. Juglanin as a natural production mainly extracted from green walnut husks of Juglans mandshurica has been defined as the functional composition among a

Acute lung injury in children is a complication showing devastating disorders linked to fibrosis progression and inflammation response. Fibrosis and inflammation response are two markers for acute lung injury. Juglanin is a natural product mainly isolated from green walnut husks of Juglans

A ethanol extract of green walnut husks (Juglans regia L.) was isolated by various chromatographic techniques yielding 5 previously unknown diarylheptanoids, namely Juglanin F (1), Juglanin G (2), Juglanin H (3), Juglanin I (4) and Juglanin J (5), respectively, together with 12 known

Even if cancer represents a burden for human society, an exhaustive cure has not been discovered yet. Low therapeutic index and resistance to pharmacotherapy are two of the major limits of antitumour treatments. Natural products represent an excellent library of bioactive molecules. Thus, tapping

Lung cancer is a leading cause of cancer-associated mortality worldwide, which has a low survival rate. Multidrug resistance (MDR) is a major obstacle that hinders the treatment of lung cancer. Doxorubicin (DOX) is an anthracycline glycoside antibiotic, having a broad spectrum of anticancer activity
