isolariciresinol/neoplasms

Lignans are widely distributed in plants and exhibit significant pharmacological effects, including anti-tumor and antioxidative activities. Here, we describe the total synthesis of schizandriside (1), a compound we previously isolated from Saraca asoca by monitoring antioxidative activity using the

A method for the characterization and quantitation of phyto-estrogenic lignans from pomegranate (Punica granatum L.) fruits and fruit-derived products by HPLC-DAD-MS(n) was developed. For this purpose, edible and nonedible parts of pomegranate (aril, peel, mesocarp, seed, and twigs), commercial

Two lignans were isolated from the heartwood of Pterocarpus santalinus by activity-guided fractionation and investigated for their biological properties and molecular mechanism of action. On the basis of their spectroscopic data, these compounds were identified as savinin (1) and calocedrin (2),

Six new lignans (2-7) were isolated from the bark of Larix olgensis var. koreana, and their structures were determined on the basis of their spectroscopic data. Seven known lignans were also obtained and identified as (+)-lariciresinol 9'-p-coumarate (1), (+)-lariciresinol, (-)-secoisolariciresinol,

Phytochemical investigation of Ephedra viridis (whole plant) led to the isolation of four lignans including (+)-9-acetoxyisolariciresinol, which is a new lignan, lariciresinol, 9-acetoxylariciresinol and isolariciresinol. All the isolates were tested for their antioxidant activity and cytotoxicity

Ginkgo biloba L., well known as living fossil, have various pharmacological activities. Eighteen compounds were isolated from Ginkgo male flowers including a novel matsutake alcohol glycoside, Ginkgoside A (1), and 17 known compounds-calaliukiuenoside (2), benzylalcohol O-α-l-arabinopyranosyl-(1 →

The needles of Pinus densiflora Siebold et Zuccarini, a representative Pinus species that grows in Korea, have been used in oriental traditional medicine as remedies for rheumatitis, hemorrhage, cancer, etc. Phytochemical examination of the needles of Pinus densiflora Siebold et Zuccarini led to the

BACKGROUND Radix Isatidis called "Ban-Lan-Gen" is one of the most commonly-used traditional Chinese medicines for antiviral, anti-inflammatory, antioxidant and antipyretic purposes. Investigate the bioaccessibility of uridine, epigoitrin, adenosine, clemastanin B, indigoticoside A and

OBJECTIVE To study the bioactive constituents of the fresh rhizome of Pinellia ternata, and provide the scientific basis for quality control. METHODS Various chromatographic techniques were used to separate and purify the chemical constituents, and their chemical structures were determined on the

Phytoestrogens of the lignan type are widely distributed in plant-derived food items and are believed to protect against hormone-dependent cancer. The richest known dietary source of lignans is flaxseed. Flaxseed has been reported to contain glycosides of secoisolariciresinol as the major lignan,
