NewTriterpenoidal Alkaloids from Buxus sempervirens

Zeitschrift für Naturforschung C, 2002
Phytochemical studies on the ethanolic extract of the roots of Buxus sempervirens of Turkish origin have resulted in the isolation of two new triterpenoidal alkaloids, (+)-16α, 31- diacetylbuxadine (1), (-)-Nb-demethylcyclomikuranine (2) along with three known natural products, (-)-cyclomikuranine (3), (-)-cyclobuxophylline-K (4) and (+)-buxaquamarine (

Low Efficacy of Isaria fumosorosea against Box Tree Moth Cydalima perspectalis: Are Host Plant Phytochemicals Involved in Herbivore Defence against Fungal Pathogens? [PDF]

Journal of Fungi, 2020
Buxus sp. is an important native and ornamental tree in Europe threatened by a serious invasive pest Cydalima perspectalis. The larvae of this moth are able to defoliate box trees and cause their death.

A New Triterpenoid Alkaloid from Buxus sempervirens

Zeitschrift für Naturforschung B, 2011
A new triterpenoid alkaloid, 16-deacetoxy-hyrcamine (1), together with six analogs, was isolated from the leaves and stems of Buxus sempervirens. Their structures were elucidated based on spectral methods and by comparison of the spectral data with those reported previously.

Comparative metabolomics reveals how the severity of predation by the invasive insect Cydalima perspectalis modulates the metabolism re-orchestration of native Buxus sempervirens. [PDF]

Plant Biol (Stuttg)
Combining NMR– and LC–HRMS–based metabolomics reveals that root and leaf metabolic changes in boxwood predated by box–tree moth occur at the same density of predation for both central and specialized metabolisms. Abstract The recent biological invasion of box tree moth Cydalima perspectalis on Buxus trees has a major impact on European boxwood stands ...

Native trees are related to advanced bird breeding phenology and increased reproductive success along an urban gradient. [PDF]

Ecology
Abstract Urban areas are altered from natural landscapes in several ways that can impact wildlife. Birds are widespread in urban areas, and it is well documented that there are phenotypic differences between urban and non‐urban conspecifics. However, little is known about which characteristics of the urban environment are driving differences. We used 9

Changes in the biological properties of sod-calcareous soils in protected areas of the Western Caucasus resulting from Buxus sempervirens L. drying

Учёные записки Казанского университета: Серия Естественные науки, 2020
The destruction of Buxus sempervirens L. in the Krasnodar region, Adygea, and Abkhazia resulted from the invasion of Cydalima perspectalis Walker introduced accidentally with planting stock in 2012. The loss of B. sempervirens L.

The Alkaloid-Enriched Fraction of Pachysandra terminalis (Buxaceae) Shows Prominent Activity against Trypanosoma brucei rhodesiense

Molecules, 2021
In the course of our studies on antiprotozoal natural products and following our recent discovery that certain aminosteroids and aminocycloartanoid compounds from Holarrhena africana A. DC. (Apocynaceae) and Buxus sempervirens L. (Buxaceae), respectively,
