Background and objectives: Several natural compounds have been identified for the treatment of leishmaniasis. Due to a few safe drugs and the side effects caused by available chemotherapy, some new drugs for treatment of leishmaniasis are requested. The genus Pulicaria (Asteraceae) is represented in the flora of Iran by five species. Phytochemical studies on Pulicaria species have revealed some...

Antibacterial and antioxidant properties of the leaves and stem essential oils (EOs) of Jatropha gossypifolia and their efficacies against infectious and oxidative stress diseases were studied in vitro. The EOs obtained using Clevenger modified apparatus were characterized by high resolution GC-MS, while their antioxidant and antibacterial properties were examined by spectrophotometric and agar...

N earlier studies concerned with the genetic regulation of pigmentation in the I garden balsam, Impatiens balsamina, the genes which determine the nature of anthocyanin pigmentation were found in individual cases to regulate also the structure of leucoanthocyanins (ALSTON and HAGEN 1958) and flavonols (CLEVENGER 1958). Thus the dominant gene H , while increasing the quantity of pelargonidin der...

This study investigated the chemical composition, and antimicrobial and anti-wood-decay fungal activities of the essential oil isolated from the leaf of Litsea acuminata (Blume) Kurata from Taiwan. The essential oil from the fresh leaves of L. acuminata was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC–FID and GC–MS. A total of 48 compounds were identif...

BACKGROUND Despite the medical discoveries of different medicines and advanced ways of treatment, statistics have shown that the number of patients is increasing. This may be due to chemical drugs used in healthcare, agriculture, and diets. This soaring demand in medicines urges us to look for natural sources such as aromatic plants and essential oils, which are rich in efficient compounds. M...

In the present study, the chemical composition of the essential oil and methanol (MeOH) extract of aerials of E. azerbaijanica were identified. Furthermore, the free radical scavenging properties of the volatile oil as well as the MeOH extract of the plant were assessed. The essential oil of the air-dried aerial parts was obtained by hydro-distillation using a Clevenger-type apparatus. The oil ...

BACKGROUND Malaria and leishmaniasis are two most significant parasitic diseases which are endemic in Iran. Over the past decades, interest in botanical repellents has increased as a result of safety to human. The comparative efficacy of essential oils of two native plants, myrtle (Myrtus communis) and marigold (Calendula officinalis) collected from natural habitats at southern Iran was compare...

Introduction: Melaleuca is a Myrtaceous genus of flowering plants about 290 species, distributed throughout Indonesia, Papua New Guinea, Australia, and Caledonia. Objective: To identify the chemical composition essential oils from leaves, twigs fruits M. quinquenervia cultivated as ornamental in Costa Rica. Methods: The were obtained through steam distillation process Clevenger type apparatus. ...

Introduction: The aim of this research was to determine the anxiolytic and antidepressant-like effects essential oils from Foeniculum vulgare aerial parts seeds. Methods: were extracted by hydro-distillation using a modified Clevenger-type apparatus chemical composition performed Gas chromatography with flame-ionization detection (GC-FID) chromatography-mass spectrometry (GC–MS). Furthermore, a...

The cell walls of plants are made up cellulose as the major composite and hydrolysis this polysaccharide has proven to be a step in extraction many biomolecules. This research was on both pure partially purified endo-1,4-D-glucanohydrolase, EC 3.2.1.4 (cellulase) assisted essential oil from seed kernels Nutmeg by using two-step protocol that involved pretreatment sample with cellulase followed ...
