چکیده
The flowers of Hyaloseris salicifolia afforded known ivasperin, while the leaves afforded ivasperin and 2-O-(6'-O-acetyl-beta-D-glucopyranosyl)-ivasperin, whose structure was determined by spectroscopic methods.

Biomimetic cyclization of cnicin to malacitanolide, a cytotoxic eudesmanolide from Centaurea malacitana.
Malacitanolide (2), a new eudesmanolide isolated from the aerial parts of Centaurea malacitana, was characterized spectroscopically. The synthesis of 2 from cnicin (1), via the epoxide 3, confirmed the structure and stereochemistry of malacitanolide, as well as its biogenetic relationship with 1. Cytotoxic activity values for 2 are significantly higher than for 1.
متن کاملIonone, iridoid and phenylethanoid glycosides from Ajuga salicifolia.
From the aerial parts of Ajuga salicifolia (L.) Schreber, a new ionone glycoside (3beta-hydroxy-7,8-dihydro-4-oxo-beta-ionol-9-O-beta-D-glucopyranoside) was isolated, along with the known compounds, corchoionoside C, 8-O-acetylmioporoside, ajugol, harpagide, 8-O-acetylharpagide, lavandulifolioside and leonosides A and B. This is the first report of the occurrence of ionone glycosides and 8-O-ac...

Three new2-(2-phenylethyl)chromone derivatives (1-3) and a new2-(2-phenylethenyl)chromone derivative (4), together with two known 2-(2-phenylethyl)chromone derivatives (5-6), were isolated from agarwood originating from Gyrinops salicifolia Ridl. The structures of compounds 1-4 were elucidated by comprehensive spectroscopic techniques (UV, IR, 1D and 2D-NMR) and MS analysis, as well as by compa...
متن کاملPhytopesticidal and repellent efficacy of Litsea salicifolia (Lauraceae) against Aedes aegypti and Culex quinquefasciatus.
Litsea salicifolia is one of the many plants used as phytopesticide, traditionally by various tribes of Assam. Of the five extracts of L. salicifolia tested for the bioactivity against Aedes aegypti and Culex quinquefasciatus, the aqueous extract was more effective compared to other extracts exhibiting bioactivity at 72 ppm against A. aegypti. The hexane extract (2000 ppm) exhibited 70% repelle...

The title compound, C(15)H(20)O(4), is a eudesmanolide isolated from the Chinese medicinal plant Carpesium tris-te Maxim. The mol-ecule contains three rings, viz. two fused six-membered rings in chair conformations and a five-membered ring in a flattened envelope conformation. In the crystal, two hy-droxy groups are involved in the formation of intra- and inter-molecular O-H⋯O hydrogen bonds. T...
