Quantifying the germination behavior of seeds against variable environmental conditions can use as a useful implement for seed ecological studies. Seed vigor depends on the temperature and moisture conditions during seed development and storage. To quantify the effects of temperature and water potential on germination response of fenugreek seeds, thermal time, hydrotime, and hydrothermal time models

As a well-known Chinese important medicine, Dendrobium resources are increasingly scarce. In order to avoid the quality problems caused by blind cultivation, we predicted the ecologically suitable areas for three species of important Dendrobium species. In this paper, using the maximum entropy model and ArcGIS, we used a database and literature search to collect the known distribution information of

Seed germination and root development are vital phases of the plant growth process; however, these steps are strongly influenced by the seed characteristics and environmental conditions. Seed priming provides a condition for uniform and rapid germination and plant establishment. Limited studies are available on the effect of seed priming to ameliorate cadmium (Cd) stress in thyme plants. Hence, the

Bergenia emeiensis (B. emeiensis) was a functional food among China folk due to high content of bergenin. However, other bioactivity-components were seldom studied. This work aimed to optimize the ultrasound-assisted extraction (UAE) of triterpenes from B. emeiensis using response surface methodology (RSM) and to investigate the effect of triterpenes extract from B. emeiensis (TEBE) on Hela cells.

Ultrasound pretreatment (USP) combined with supercritical CO2 extraction (SCE) was carried out to obtain Iberis amara seed oil (IASO) in the present study. The maximal oil yield (25.28 ± 0.39 %, w/w, dry basis) acquired by SCE from ultrasound-treated seeds with ultrasonic energy density of 1.25 W/mL during 10 min, was 28 % higher than that obtained from the untreated seeds. Furthermore, the obtained

The aim of the present work is to investigate the generalization possibilities of models describing the kinetics of essential oils extraction and the relevance of the adopted assumptions for their development. A database of 132 extraction kinetics was built on the basis of works reported in the literature. This data analysis showed two types of kinetics which differ by the presence or not of an inflection

Horsemint (Mentha longifolia (L.) L.) is a less studied, wild-growing species. Aim of the experiments was to define effective extraction method providing highest antioxidant capacity and polyphenol content from the plant, for long-term goal of food preservation uses. We applied Soxhlet and ultrasonic (US) extraction, both with methanol (MeOH) and ethanol: water in 7:3 (WA) as solvents. Thirty-six accessions

The genus Crataegus L. involving several hundred species is distributed throughout the temperate zne of the nothern hemisphere. Nevertheless, only a few species are included in Pharmacopoeias and used for medical purpose. As hawthorn plants usually grow in small groups, the harvesting of raw material is complicated. The search of species suitable for further inclusion in Pharmacopoeia may facilitate

Seeds of 14 Iranian and one Indian cumin landraces were grown to produce freshly matured seeds. Freshly matured seeds were tested for germination, embryo and seed size, fresh and dry weights. Fresh seeds were after ripened at the room temperature for 4 or 20 months and were tested for germination. The effects of cold stratification, gibberellic acid (GA3), and incubation temperature investigated on

For herbal drugs used for the production of medicinal products, the European Pharmacopoeia has established limits for pesticide residues in Chapter 2.8.13. For pesticide substances not listed in this chapter and whose presence is suspected the limits set by Regulation (EC) No. 396/2005 are applicable. This publication presents an evaluation of a database which includes 3.398.655 sets of data collected
