Thyme (Thymus vulgaris L.) is a commonly used flavoring agent and medicinal herb. Several chemotypes of thyme, based on essential oil compositions, have been established, including (1) linalool; (2) borneol; (3) geraniol; (4) sabinene hydrate; (5) thymol; (6) carvacrol, as well as a number of multiple-component chemotypes. In this work, two different T. vulgaris essential oils were obtained fro...

A large proportion of phytophagous insects show host plant specificity (monophagy or oligophagy), often determined by host secondary chemistry. Yet, even specialists can be negatively affected by host chemistry at high levels or with novel compounds, which may manifest itself if their host species is chemically variable. This study tested for reciprocal effects of a specialist tortoise beetle (...

Iran is one of the major centres diversity for Salvia, with 58 species which 25% are endemic. A literature-based survey chemical profile Salvia essential oil found in was carried out. As a result, 46 belonging to genus were identified their composition. concise review scientific literature pertaining components oils and volatile fractions presented. The present showed that Iranian have been cla...

background & aim: myrtle (myrtus communis l.), is an important medicinal plant that is used for pharmacological uses and conservation of environments (for example preventing the soil erosion) regards to its specific condition habitat.experimental: in this research, phytochemical variations of the essential oils from different populations of myrtle collected from fars (saydan, cheshme-ali, a...

Despite the urgent need for effective antimalarial drugs with novel modes of action no new chemical class of antimalarial drug has been approved for use since 1996. To address this, we have used a rational approach to investigate compounds comprising the primary benzene sulfonamide fragment as a potential new antimalarial chemotype. We report the in vitro activity against Plasmodium falciparum ...

Abstract The 3ADON chemotype of Fusarium graminearum predominates in northern Europe, whereas the 15ADON is predominant central and southern Europe. Therefore, it has been suggested that there are two F. populations which may have specialized to different host plants. aim present work was test this hypothesis by comparing European isolates (15ADON chemotype) from Russia (3ADON Finland infection...

Aflatoxins are produced by Aspergillus flavus and A. parasiticus in oil-rich seed and grain crops and are a serious problem in agriculture, with aflatoxin B₁ being the most carcinogenic natural compound known. Sexual reproduction in these species occurs between individuals belonging to different vegetative compatibility groups (VCGs). We examined natural genetic variation in 758 isolates of A. ...

Four crosses were made between inbred Cannabis sativa plants with pure cannabidiol (CBD) and pure Delta-9-tetrahydrocannabinol (THC) chemotypes. All the plants belonging to the F(1)'s were analyzed by gas chromatography for cannabinoid composition and constantly found to have a mixed CBD-THC chemotype. Ten individual F(1) plants were self-fertilized, and 10 inbred F(2) offspring were collected ...
