Identification and physiochemical parameters such as solubility, loss on drying, viscosity, pH, swelling index, starch and gum constituents were determined in natural polymers and showed satisfactory results. Spectral studies established the compatibility of natural polymers. The drug release kinetics in preliminary trial batches showed that tablets containing natural mucilages and gum showed a prolonged drug release comparable to Carbopol 974P and Methocel K4M. Also, all tablets showed a satisfactory drug permeability flux...

This triple-blind trial examined the effects of Calendula officinalis vaginal cream on the treatment of vaginal Candidiasis (primary outcome) and sexual function (secondary outcome). Married women aged 18-45 years with vaginal Candidiasis (n = 150) were recruited from April to October 2014 and randomized into Calendula and clotrimazole groups, using 5-gram vaginal cream every night for 7 nights. Clinical and laboratory assessments were conducted at 10-15 and 30-35 days after intervention and the female sexual function index was assessed at 30-35 days...

BACKGROUND: The flower bug Orius sauteri (Poppius) (Hemiptera: Anthocoridae) is widely used as a biocontrol agent against thrips and aphids infesting greenhouse vegetables in Asia. The survival and oviposition of such predators, as well as biocontrol services they provided, may be enhanced by adding extra floral resources to the crops. In the current study, we investigated the effects of the plant Calendula officinalis L., used as a floral resources, for promoting the control of Myzus persicae (Sulzer) and Frankliniella occidentalis (Pergande) by O...

Edible flowers provide new colours, textures and vibrancy to any dish, and apart from the "glam" factor, they can constitute new sources of bioactive compounds. In the present work, the edible petals and infusions of dahlia, rose, calendula and centaurea, were characterized regarding their nutritional value and composition in terms of hydrophilic and lipophilic compounds. Carbohydrates were the most abundant macronutrients, followed by proteins and ash. Fructose, glucose and sucrose were identified in all the petals and infusions...

Supercritical extracts of marigold (ME) were produced and characterized. The bioaccessibility of terpenes, especially that of pentacyclic triterpenes (PT), the particle-size distribution and antioxidant activity after the in vitro co-digestion of ME with olive oil (OO), were determined. ME produced without co-solvent was richer in taraxasterol, lupeol, α-amyrin and β-amyrin than extracts with co-solvent. All terpenes showed high bioaccessibility without OO (>75%). Significant correlations were found between the molecular properties of compounds (logP and number of rotatable bonds) and their bioaccessibility...

The present paper aims to perform a screening of native plants growing in Kettara mine-Marrakech (Southern Morocco) for its phytoremediation. Plants and soil samples were collected and analyzed for Pb, Zn, Cu and Cd concentrations at several sites in the mine. The results showed that the soil in the vicinity of Kettara mine is deficient in major elements and contain toxic levels of metals. Spontaneously growing native plants were botanically identified then classified into 21 species and 14 families. Significant difference was observed among the average concentrations of four heavy metals (Pb, Zn, Cu and Cd) in plants (P ≤ 0...

Monitoring patterns in biodiversity and phenology have become increasingly important given accelerating levels of anthropogenic change. Long-term monitoring programs have reported earlier occurrence of spring activity, reflecting species response to climate change. Although tracking shifts in spring migration represents a valuable approach to monitoring community-level consequences of climate change, robust long-term observations are challenging and costly. Audio recordings and metrics of bioacoustic activity could provide an effective method for monitoring changes in songbird activity and broader biotic interactions...

Antiseptic rinses have been successfully used in inflammatory states of the gums and oral cavity mucosa. Antibacterial effects of chlorhexidine, essential oils and some herbs are well documented. Reaction of host tissue to these substances has much poorer documentation. The aim of the study was to analyse the influence of chlorhexidine (CHX), essential oil (EO: thymol, 0.064%; eucalyptol, 0.092%; methyl salicylate, 0.060%; menthol, 0.042%) mouth rinses and salvia, chamomile and calendula brews on fibroblast biology in vitro...

An innovative nanocapsule formulation for parenteral administration using selected vegetable oils (mango, jojoba, pequi, oat, annatto, calendula, and chamomile) was developed that has the potential to encapsulate various drugs. The vegetable oil-loaded nanocapsules were prepared by interfacial deposition and compared with capric/caprylic triglyceride-loaded lipid core nanocapsules. The major objective was to investigate the effect of vegetable oils on particle size distribution and physical stability and to determine the hemolytic potential of the nanocapsules, considering their applicability for intravenous administration...

Several retinal degenerative diseases cause vision loss and retinal cell death. Currently, people face prolonged exposure to digital screens, rendering vision protection from light exposure a critical topic. In this study, we designed a complex lutein formula (CLF) by combining several natural compounds: Calendula officinalis, Lycium barbarum, Vaccinium myrtillus, Cassia obtusifolia, and Rhodiola rosea. In addition, we evaluated the protective effects of the formula on retinal functions in an animal model for light-induced retinal degeneration...

The active fraction and/or compounds of Calendula officinalis responsible for wound healing are not known yet. In this work we studied the molecular target of C. officinalis hydroethanol extract (CEE) and its active fraction (water fraction of hydroethanol extract, WCEE) on primary human dermal fibroblasts (HDF). In vivo, CEE or WCEE were topically applied on excisional wounds of BALB/c mice and the rate of wound contraction and immunohistological studies were carried out. We found that CEE and only its WCEE significantly stimulated the proliferation as well as the migration of HDF cells...

CONTEXT: Calendula officinalis L. (Asteraceae) has been traditionally used in treating inflammation of internal organs, gastrointestinal tract ulcers and wound healing. OBJECTIVE: The present study investigates the effect of ethanol extract (95%) of Calendula officinalis flowers in l-arginine induced acute necrotizing pancreatitis in rats. MATERIALS AND METHODS: Rats were divided into four groups: normal control, l-arginine control, Calendula officinalis extract (COE) treated and melatonin treated (positive control), which were further divided into subgroups (24 h, day 3 and 14) according to time points...

The aim of the present study was to assess the antifungal and anti-toxinogenic activity of 15 essential oils (EOs) against three fungi of the genus Aspergillus (A. parasiticus KMi-227-LR, A. parasiticus KMi-220-LR and A. flavus KMi-202-LR). The minimum inhibitory doses (MIDs) of the tested essential oils and their antifungal activity were determined using the micro-atmosphere method. The original commercial essential oil samples of Jasminum officinale L., Thymus vulgaris L., Syzygium aromaticum (L.) Merrill & Perry, Rosmarinus officinalis L...

A double-stranded RNA (dsRNA) HBJZ1506 recovered from the phytopathogenic fungus Erysiphe cichoracearum infecting Calendula officinalis in Jingzhou, Hubei Province, China, was sequenced. HBJZ1506 comprises 11,908 nucleotides (nt) and contains a 11,859-nt-long open reading frame (ORF) coding for a polypeptide that is 61 % identical to that of a putative endornavirus named grapevine endophyte endornavirus (GeEV). The putative polyprotein has an RNA-dependent RNA polymerase (RdRp) domain and an RNA helicase domain, which show homology to and have an arrangement that is similar to that of their counterparts in approved or putative endornaviruses...

Chemical mutagenesis is an efficient tool used in mutation-breeding programs to improve the vital characters of the floricultural crops. This study aimed to estimate the effects of different concentrations of two chemical mutagens; sodium azide (SA) and diethyl sulfate (DES). The vegetative growth and flowering characteristics in two generations (M1 and M2) of calendula plants were investigated. Seeds were treated with five different concentrations of SA and DES (at the same rates) of 1000, 2000, 3000, 4000, and 5000 ppm, in addition to a control treatment of 0 ppm...
