The chromatography fractionation of the hexane, chloroform and ethyl acetate extracts from the leaves and stems of Rourea doniana Baker, Connaraceae, resulted in the isolation of five triterpenes (lupeol, lupenone, α-amyrenone, β-amyrenone, and taraxerol), a flavonol (7,4’-dimethylkaempferol), a coumarin (scopoletin) and four phytosteroids (β-sitosterol, stigmasterol, β-sitosteryl-3-Oβ-D-glucop...

Rhamnus virgatus Roxb. (Syn. R. dahuricus Pall.), Rhamnaceae, is a deciduous shrub, 1.8}4.5 m in height, found throughout the Himalayas at an altitude of 800}3000 m. Aerial parts (twigs with leaves) of R. virgatus were collected in July 1996, from Musoli, Pauri District, Garhwal, UP, India and identi"ed by Dr. L.R. Dangwal, Department of Botany, HNB Garhwal University Srinagar (Garhwal), India....

Two new antifungal withanolides, (1) and (2) have been isolated from the defatted methanolic extract of Ajuga parviflora. Their structures were established as 3/3,17/3,20-trihydroxyl-oxo-(20/?, 22/?)-witha-5,14,24-trienolide (1), 28-hydroxy-14,20-epoxy-l-oxo-(22/?)-witha2,5,24-trienolide (2) on the basis of spectroscopic data including two dimensional NMR tech­ niques. The pyrrolizidine alkaloi...

From the water-soluble portion of the methanol extract of the fruit of Carum ajowan (ajowan), which has been used as a spice and medicine, 25 compounds, including five new monoterpenoid glucosides, a new monoterpenoid, two new aromatic compound glucosides, and two new glucides, were obtained. Their structures were clarified by spectral investigation.

{A parser based on Categorial Grammars is described. It is capable of parsing constituents independently, and employs a chart without top-down control. It can be used to impose contraints on the input, or to enquire about the possible nal compositions.
