A set of 10 4,7-dimethoxy-1,3-benzodioxole derivatives based on a lead compound previously discovered by our group, SY-1, which was isolated from Antrodia camphorata, were evaluated for their in vitro inhibitory activity on human colorectal carcinoma cells (COLO 205). Structure-activity relationship studies of the 10 compounds indicated the importance of the chain length of the alkyl group at t...

Background and objectives: Phlomis bruguieri Desf. (Lamiaceae) is a perennial herbaceous plant distributed in Iran, Turkey and Iraq. Despite medicinal potentials of this species, the current knowledge on its phytochemical constituents is limited. The aim of the present study was to investigate the phytochemical constituents of the essential oil and various extracts of this species. Methods: Ess...

Background: The genus Psammogeton Edyew. which belong to the umbelliferae family, is found in central areas of Asia. This genus consists of six species widespread in the sandy dunes of deserts. Among the four species present in Iran, Pssamogeton canescens (DC.) vatke is distributed in regions of Iran central. Objective: The aim of this study is to determine the chemical composition of essenti...

Exhaustive hydro-distillation of the leaves of Piper aduncum and fruits of Piper gibbilimbum (Piperaceae) afforded colorless and pale orange colored oils in 0.35 and 0.30 % yields, respectively. Detailed chemical analysis by GC/MS indicated the volatile constituents of Piper aduncum to be composed of dill apiole (43.3%), beta-caryophyllene (8.2%), piperitione (6.7%) and alpha-humulene (5.1%), w...

The chemical composition and antimicrobial activity of essential oils obtained from leaves of two Myrtaceae species-Eugenia uniflora L. and Plinia trunciflora (O. Berg) Kausel-were determined. Analysis by GC/MS as well as determination of Kovatz indexes indicated atractylone (26.78%) and curzerene (17.96%) as major constituents of E. uniflora oil and α-cadinol (19.15%), apiole (11.15%) and cube...

Chemical fungicides are an important component in disease management for most crops. As part of a program to discover natural product-based fungicides, several sensitive assay systems have been developed for the evaluation of naturally occurring antifungal agents. In this study, we focused on the discovery and evaluation of new natural product-based fungicides from Angelica sinensis (Dong Quai)...
