Consumer preference for medicinal plants in Oyo Metropolis, Nigeria
Ill-health is seen as a great factor that brings about the absenteeism of individuals at work as well as the absence of the person(s) attending to the needs of the sick. This greatly reduces the income that can accrue to individuals due to loss of man days at work which in turn increases the poverty level of individuals. In order to prevent this, curative measures are used. In recent times, there seems to be a drastic...

Essential oil yield and trichomes structure in two sweet marjoram (origanum majorana L.) varieties under salt stress
Origanum majorana L. shoots were investigated for their essential oil (EO) yield, composition and the structures responsible for its biosynthesis. Shoots EO was extracted by hydrodistillation and composition was determined by gas chromatography–mass spectrometry (GC-MS) method. Fresh Leaves were observed by light microscopy (LM). Plants were cultivated for 17 days in a basal medium supplemented with...

A perspective on geoherbalism: An example of scutellariae radix biogeography based on three chloroplast DNA regions
The term ‘geoherbalism’ is extensively used for both academic and commercial purposes. To examine the recent application of this term to a frequently used herbal medicine, 231 samples of genuine scutellariae radix, Scutellaria baicalensis, were collected from 13 populations, covering almost the entire distribution range. In addition, we sampled its two succedanea, that is, 39 samples from two...

Simultaneous quantification of four saponins, three alkaloids and three fatty acids in Solanum nigrum Linn. by HPLC-ELSD
A new high-performance liquid chromatography (HPLC) coupled with evaporative light scattering detection (ELSD) method was developed, and the quantity of four major saponins, three alkaloids and three fatty acids were determined simultaneously in Solanum nigrum Linn, a commonly used traditional Chinese medicine (TCM) herb. The simultaneous separation of four saponins, three alkaloids and three fatty acids was...

Antioxidant, hepatoprotective, and ameliorative effects of Azadirachta indica on Eimeria papillata-induced infection in mice
Azadirachta indica (neem) is used in traditional medicine for its pharmacological properties. Here, we investigated the effects of neem on the outcome of coccidiosis caused by Eimeria papillata in mice. Coccidiosis was induced by infection of mice with 103 sporulated oocysts of E. papillata. The methanolic extract of neem (Azadirachta indica) leaves (500 mg/kg) was used in...

Impact of arbuscular mycorrhizal fungi on the growth and related physiological indexes of Amorpha fruticosa
Through inoculating Amorpha fruiticosa with arbuscular mycorrhizal (AM) fungi and without, the seedlings’ growth indexes, dynamic characteristics of plant endogenous hormone levels, soluble sugar contents in roots and in leaves respectively, and physiological characteristics of seedlings utilizing nitrogen (N), phosphorous (P), were systematically studied. The results showed that both the two tested AM...

Effect of diverse use of nitrogen sources on grain yield, harvest index, nitrogen-use efficiency and phenological development of hybrid maize (Zea mays L.)
A two-year field experiment was conducted to evaluate the effect of diverse use of nitrogen sources on grain yield, harvest index, nitrogen-use efficiency (NUE) and phenological development of hybrid maize (Zea mays L.) at the Agronomic Research Area, University of Agriculture, Faisalabad during autumn of 2008 and 2009. Experiments were laid out in a randomized complete block design (RCBD) with factorial...

Qualitative and quantitative determination of polyphenol content of Scilla bifolia
High-performance liquid chromatography with mass spectrometry and UV detection was applied for qualitative of eighteen polyphenols and quantitative determination of fourteen of them in Scilla bifolia bulbs and aerial parts. Caffeic acid, p-coumaric acid, ferulic acid, luteolin and apigenin were found in all hydrolysed and unhydrolysed sample extracts. Sinapic acid was detected and quantified only in hydrolyzed...

Anti-aging effect of black rice against H2O2-induced premature senescence
This study was focused on the anti-aging effect of black rice under stress-induced premature senescence (SIPS) of WI-38 human diploid fibroblasts cells caused by hydrogen peroxide (H2O2), a well-established experimental model of cellular aging. The protective effect of the MeOH extract from black rice against H2O2-induced premature senescence was investigated using WI-38 cells by evaluating the cell viability, lipid...

A preliminary study of leaf morphology and flow cytometry in the Vatica diospyroides Symington, endangered medicinal plant of Peninsular Thailand
In modern drug discovery program, Vatica diospyroides Symington consisted of chemical constituents that were found as anticancer in human. V. diospyroides was described as endangered species, and its tree is puzzled by means of leaf forms. Investigating the unique features was very important to support the program. To classify these features, leaf traits and C-DNA values were investigated. Leaf...
