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 →
To study the chemical composition and their anti-inflammatory activities of honeysuckle (Lonicera japonica Thunb.) roots, seventeen compounds were isolated from the roots of L. japonica Thunb. by various chromatography, including silica gel, Sephadex LH-20 and preparative HPLC. Their structures were
Using various chromatographic methods, a new piperidinone alkaloid, (3S)-3-{4-[(1E)-3-hydroxyprop-1-en-1-yl]-2-methoxyphenoxy}piperidin-2-one (1), together with 10 known compounds, bergapten (2), xanthotoxol (3), isopimpinellin (4), isobergapten (5), heratomol-6-O-β-d-glucopyranoside (6), scopoletin
In order to find potential therapeutic agents on lung inflammatory conditions, the extracts of Acanthopanax divaricatus var. albeofructus were prepared and its constituents were isolated. They include lignans such as (+)-syringaresinol (1), acanthoside B (2), salvadoraside (3) and acanthoside D (4),
Three phenylpropanoid glycosides (salidroside, syringin and coniferin) and one lignan (phillyrin) isolated from the leaves of Phillyrea latifolia L. (Oleaceae) were tested for interactions with the cyclo-oxygenase and 5-lipoxygenase pathways of arachidonate metabolism in calcium-stimulated mouse
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
