TOBACCO STREAK VIRUS INFECTING BUXUS SEMPERVIRENS

Acta Horticulturae, 2006
Box-tree (Buxus sempervirens) is an evergreen ornamental plant, appreciated for its small, dark-green glossy leaves attractive in all seasons, and mostly used as borders in the gardens. In the fall of 2001, three pot plants of box-tree coming from Tuscany region (central Italy) were sent to DiSTA-Plant Pathology of the Bologna University to be examined

Box (Buxus sempervirens L.)

Quarterly Journal of Crude Drug Research, 1977
AbstractCalled boxwood from ancient times, the close-grained hard wood had long been used for making boxes and chests because it takes a very high polish. It was and apparently still is in great demand for engraving blocks, rulers, musical instruments, and shuttles.

Chemical Constituents ofBuxus sempervirens

Planta Medica, 1988
BUXUS SEMPERVIRENS (Buxaceae) of Turkish origin has yielded a new steroidal alkaloid, (-)-( Z)-buxenone ( 1) along with its known isomer (-)-( E)-buxenone ( 2). The plant also yielded 4',5-dihydroxy-3,3',6,7-tetramethoxyflavone ( 3) and artemetin (5-hydroxy-3,3',4',6,7-pentamethoxyflavone) ( 4).

Buxaline-C from Buxus sempervirens

Chemistry of Natural Compounds, 1975
A new alkaloid buxaline-C has been isolated fromBuxus sempervirens cultivated in Tashkent. The results of a comparison of the physicochemical properties of the products of the hydrolysis of buxaline-C and those of cycloprotobuxine C have enabled the structure and configuration of buxaline-C to be determined as 3β-acetylmethylamino-20β-dimethylamino-4,4,

Pseudocyclobuxin-D from Buxus sempervirens

Chemistry of Natural Compounds, 1973
1. A new alkaloid, pseudocyclobuxin-D, has been isolated from the leaves and fine flowers ofBuxus sempervirens. The results of a comparison of the physicochemical properties of pseudocyclobuxin-D and its derivatives with cyclobuxin-D and its derivatives has shown that the alkaloid isolated is an isomer of cyclobuxin-D and has the structure of 14α ...

Steroidal alkaloids from leaves of Buxus sempervirens

Phytochemistry, 1991
Abstract Leaves of Buxus sempervirens of Turkish origin have yielded three new steroidal alkaloids, (+)-sempervirine, (−)-31-acetyl-cyclomicrophylline-A and (−)-benzoylbuxidienine. Two known bases (+)-buxamine-C and (+)-buxabenzamidienine have also been isolated for the first time from this plant. The structures have been determined on the basis of

Semperviramidine—A new steroidal alkaloid from Buxus sempervirens

Phytochemistry, 1988
Abstract From leaves of B. sempervirens a new steroidal alkaloid (+)-semperviramidine has been isolated and structurally elucidated as (20S)-16α-acetoxy-3β-benzoylamino-20-dimethylamino-4,4,14-trimethyl-9β,19-cyclo-5α-pregnane (1) by spectroscopic methods.
