Artemisinin extracted at low solid loading causes low product concentration and high organic solvent usage. In this study, extraction in high solids of Artemisia annua by periodic peristalsis was proposed to increase the concentration of artemisinin and improve the extraction efficiency. The results showed that the artemisinin yield, extracted from leaves of Artemisia annua, increased by 33.9%-46.5%

Ultrasonic probe extraction of phenolic compounds from olive leaves was modelled and optimized by using soft computing methods. The effects of amplitude, irradiation time, solvent (MeOH/EtOH) concentration, probe position and duty cycle on total phenolic content (TPC), oleuropein content (OLEc) and total antioxidant activity (TAA) of olive leaf extracts were investigated in multi-objective perspective

In this work, the performance of ultrasonic-assisted extraction (UAE) in simultaneously enhancing the total flavonoid content (TFC) and antioxidant activities of India Moringa oleifera L. leaves (MOLs) was analyzed by using response surface methodology (RSM). Based on the results of the single-factor experiment, a three-factor five-level central composite design (CCD) was proposed. RSM results indicated

Osmanthus fragrans (Lour) flower is a typical fragrant herb in eastern countries containing multiple bioactive compounds, the extract of which has been widely used as a natural antioxidant additive in food and cosmetics. However, the existing extraction methods use organic solvents during the extraction process, which is non-eco-friendly and harmful to human health. In this study, we introduce, to

Multiple ecological factors acting at different spatial scales are responsible for abundance and distribution of plant species. Therefore, in order to conserve and manage various species, it is crucial to examine species relationships with these factors. This study is aimed to model current distribution and assess the various factors influencing distribution of Dactylorhiza hatagirea (D.Don) Soo, a

Salvia is one of the most important medicinal plant genus in the Lamiaceae family. The genetic diversity of 85 genotypes belonging to 20 species from the native flora of the Hatay, province of south-central part of Turkey, was analyzed using six microsatellite markers. These markers (SoUZ022, SoUZ024, SoUZ025, SoUZ026, SoUZ027, and SoUZ028) were derived from S. officinalis and were tested in this study

Blettila striata (Thunb.) Reichb.f. is an important ornamental and herbaceous medicinal plant. However, natural resources are endangered and breeding and improvement of the medicinal plant using modern biotechnology are urgently needed. Increasing the harvest biomass is critical to the total yield of bioactive substances. The ‘MBS’ variety of Bletilla striata could be an ideal parental line for genetic

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

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

Species of the genus Achyranthes are known to possess immense medicinal value leading to its inclusion in Ayurveda. A. aspera has been widely used in all the traditional Indian systems of medicine, while A. bidentata is mentioned in Chinese, Japanese and Korean pharmacopoeias. Molecular authentication of any medicinal plant species is a prerequisite for the success of its herbal business. Presently

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

Moringa oliefera Lam. is the most widely cultivated species among the members of Moringa genus in tropics for its nutritional and medicinal values. Almost all plant parts have been used in human's nutrition and therapy. The molecular characterizations are required for effective improvement for better utilization. In the present study, genetic variation in ten individual Moringa oleifera plants were

Curcuma caesia belonging to Zingiberaceae family is considered as an endangered plant. It has many medicinal properties which can cure different health disorders and due to its potential pharmaceutical and industrial applications, conservation of this species is required. In this present investigation, morphological diversity, Mahalanobis D2 analysis, correlation, path analysis and association study

In many parts of the world, sawdust is a common wood industrial waste that is either wasted or used as fuel. Sawdust has low weight, good drainage and is inexpensive. This study assesses the potential of wood sawdust to be used as a viable substrate for soilless garlic production. In two experiments, garlic (Allium sativum) was grown in plastic bags containing six different types of sawdust substrates

The present study was designed to evaluate the effect of different solvents on the extraction of bioactive compounds, antioxidant and cytotoxic potentials of dwarf date palm (Phoenix loureiroi). The leaves were successively extracted with low to high polar solvents (petroleum ether, chloroform, ethyl acetate, methanol and water) using the Soxhlet method. Spectrophotometric determination of leaves extracts

Over recent years species distribution models have been used for the identification of suitable cultivation zones for native plant species. Valeriana carnosa is one of the most frequently used native plants in Patagonian popular medicine, its underground organs being obtained from natural populations. Considering the growing market demand, it is now necessary to design strategies for the cultivation

Crepidiastrum denticulatum (Korean common name: i-go-deul-ppae-gi) is a valuable medicinal plant used in the pharmaceutical industry and as a raw material of functional foods. In this study, we investigated the effect of light quality on C. denticulatum growth, with the goal of improving the species’ biomass and bioactive compound content when grown in plant factories with artificial lighting. Three-week-old

Piper methysticum Forst., commonly referred to as kava, has been used medicinally and recreationally by inhabitants of the South Pacific Islands for centuries. Kavalactones present in roots and aerial parts are regarded as the bioactive compounds responsible for the relaxant effects, and for mitigating anxiety and stress-related conditions.
