Molecules, Vol. 24, Pages 501: HPLC Analysis and Skin Whitening Effects of Umbelliprenin-containing Extracts of Anethum Graveolens, Pimpinella Anisum, and Ferulago Campestris
Salvatore Genovese
Umbelliprenin has recently been shown to have great potential as a skin whitening agent. Wishing to investigate the same effect in plant species known to biosynthesize this coumarin, three plants belonging to the Apiaceae family, namely Anethum graveolens L. (dill), Pimpinella anisum L. (anise), and Ferulago campestris (Besser) Grecescu (field ferula) were screened by HPLC analysis for their respective content of umbelliprenin in extracts obtained with different solvent mixtures and by maceration and ultrasound-assisted processes. EtOH was shown to be the best solvent, providing umbelliprenin yields...

Shikimic Acid Promotes Oligodendrocyte Precursor Cell Differentiation and Accelerates Remyelination in Mice
AbstractThe obstacle to successful remyelination in demyelinating diseases, such as multiple sclerosis, mainly lies in the inability of oligodendrocyte precursor cells (OPCs) to differentiate, since OPCs and oligodendrocyte-lineage cells that are unable to fully differentiate are found in the areas of demyelination. Thus, promoting the differentiation of OPCs is vital for the treatment of demyelinating diseases. Shikimic acid (SA) is mainly derived from star anise, and is reported to have anti-influenza, anti-oxidation, and anti-tumor effects. In the present study, we found that SA significantly promoted the differentiatio...

Biosynthesis of methyleugenol and methylisoeugenol in Daucus carota leaves: Characterization of eugenol/isoeugenol synthase and O-Methyltransferase
Publication date: March 2019Source: Phytochemistry, Volume 159Author(s): Mosaab Yahyaa, Anna Berim, Bhagwat Nawade, Muhammad Ibdah, Natalia Dudareva, Mwafaq IbdahAbstractCarrot (Daucus carota subsp. sativus) is a widely cultivated root vegetable of high economic importance. The aroma of carrot roots and aboveground organs is mainly defined by terpenes. We found that leaves of orange carrot cultivar also produce considerable amounts of the phenylpropenes methyleugenol and methylisoeugenol. Notably, methyleugenol is most abundant in young leaves, while methylisoeugenol is the dominant phenylpropene in mature leaf tissue. The...

IJERPH, Vol. 15, Pages 2774: The Comorbidity of Gambling Disorder among Macao Adult Residents and the Moderating Role of Resilience and Life Purpose
uan Zhang
Macao, China’s only city with legalized casinos, has maintained a high prevalence of gambling participation and gambling disorder (GD) over the past decade. The mental health risks associated with such high levels have been overlooked. In order to estimate the comorbid prevalence of GD with depression, anxiety, and Internet gaming disorder (IGD) and to explore the potential buffering effect of psychological resilience and purpose in life, this study obtained a representative adult Chinese sample (N = 1000, 44% male, aged 18–97 years) from a telephone survey conducted between Octobe...

Development of A Comprehensive Biological Hazard ‐Proof Packaging Film with Insect‐Repellent, Antibacterial, and Antifungal Activities
AbstractA multifunctional film with insect ‐repellent and antimicrobial activities was developed. Star anise (Illicium verum Hook. f.) oil (SO) proved to be effective in repellingPlodia interpunctella (H übner) (Lepidoptera: Pyralidae) larvae and was selected as an insect‐repellent agent. Thymol, a compound that demonstrated strong growth inhibition activities against bothStaphylococcus aureus andPenicillium roqueforti, was selected as an antimicrobial agent. Based on the release profile test of SO using various plastic films, polypropylene (30 μm; PP 30) and low‐density polyethylene (20 μm; LDPE 20) were selected...

Chemical composition of essential oils from the apiaceae family, cytotoxicity, and their antifungal activity in vitro against candida species from oral cavity.
Abstract
The aims of this research were: evaluate the chemical composition and the cytotoxicity of the Cuminum cyminum (cumin), Anethum graveolens (dill), Pimpinella anisum (anise) and Foeniculum vulgare (fennel) essential oils, as well as their antifungal activity in vitro against ten Candida spp. isolates. The chemical composition of the oils was analyzed by means of gas chromatography coupled with mass spectrometry (GC/MS). The cytotoxicity assays were performed, using the cell proliferation reagent WST-1 in L929 mouse fibroblasts (20x103 well-1). The determinate the Minimum Inhibitory Concentration (MI...

IJERPH, Vol. 15, Pages 2147: Investigation of the Effects of Purpose in Life, Grit, Gratitude, and School Belonging on Mental Distress among Chinese Emerging Adults
This study tested the direct and indirect effects (via purpose in life) of gratitude, two aspects of grit (i.e., consistency of interest and perseverance of effort), and school belonging on three indicators of mental distress (i.e., depression, anxiety, and stress). A total of 468 Chinese university students (58.3% female), aged 18 to 27, in Macao, China responded to an anonymous questionnaire between April to May, 2016. As expected, all psychosocial factors were negatively associated with all three indicators of mental distress (r = &minus;0.15 to &minus;0.42, p &lt; 0.05), with the exception of pe...

Metabolic engineering strategies for enhanced shikimate biosynthesis: current scenario and future developments.
Abstract
Shikimic acid is an important intermediate for the manufacture of the antiviral drug oseltamivir (Tamiflu®) and many other pharmaceutical compounds. Much of its existing supply is obtained from the seeds of Chinese star anise (Illicium verum). Nevertheless, plants cannot supply a stable source of affordable shikimate along with laborious and cost-expensive extraction and purification process. Microbial biosynthesis of shikimate through metabolic engineering and synthetic biology approaches represents a sustainable, cost-efficient, and environmentally friendly route than plant-based methods. Metab...

Molecules, Vol. 23, Pages 1668: Antimicrobial Activity of Five Essential Oils against Bacteria and Fungi Responsible for Urinary Tract Infections
Mancianti
Urinary tract infections are frequently encountered in small animal practice. Escherichia coli and Enterococcus spp. are the most common agents associated to these infections, even though other bacteria and yeasts, such as Candida albicans and Candida famata, may be involved. In view of the increasing problem of the multi-drug resistance, the aim of this study was to investigate the antimicrobial activity of essential oils obtained from star anise (Illicium verum Hook.f.), basil (Ocimum basilicum L.), origanum (Origanum vulgare L.), clary sage (Salvia sclarea L.) and thymus (Thymus vulgaris L.) against multid...

Cross-reactivity by botanicals used in dietary supplements and spices using the multiplex xMAP food allergen detection assay (xMAP FADA).
Abstract
Food allergies affect some 15 million Americans. The only treatment for food allergies is a strict avoidance diet. To help ensure the reliability of food labels, analytical methods are employed; the most common being enzyme-linked immunosorbent assays (ELISAs). However, the commonly employed ELISAs are single analyte-specific and cannot distinguish between false positives due to cross-reactive homologous proteins; making the method of questionable utility for regulatory purposes when analyzing for unknown or multiple food allergens. Also, should the need arise to detect additional analytes, extens...
