The oils air-dried samples were obtained by hydrodistillation. yield (w/w%) stages order vegetative (2.0%), early (1.7%), (0.6%) set. analyzed gas chromatography (GC) GC-mass spectrometry (GC-MS). In total, 36, 33, 16 components identified quantified representing 94.47%, 95.91%, 99.62% oil, respectively....

Total phenols, flavonoids, flavonols, and flavanols of the methanolic extract aerial part Artemisia herba-alba were determined. The was analyzed by liquid chromatography with photodiode array coupled electrospray ionisation mass spectrometry allowed to identify 10 phenolic compounds. Apigenin-6-C-glycosyl flavonoids caffeoylquinic acids identified. Chlorogenic acid 1,4 dicaffeoylquinic being major constituents. essential oil obtained hydrodistillation gas chromatography–mass spectrometry....

Abstract Date palm pits are highly available and inexpensive date by‐products, representing a valuable source of natural antioxidants, particularly phenolic compounds. pit extract (DPPE) was prepared from these waste products characterized for its content in vitro antioxidant activity. Profiling DPPE by liquid chromatography coupled with mass spectrometry (LC/MS) showed the presence dimers trimers (epi)catechin as main constituents. Alginate‐based films four increasing concentrations (10%,...

Introduction Diabetes is a major health issue that has reached alarming levels worldwide. Although their effectiveness, the antidiabetic drugs have many side effects such as cardiovascular diseases, kidney failure, and hepatic complications. Many plant species of genus Salvia L. “Arabian desert sage” ( deserti ) should began to be focus phytochemical bioactivity studies. Methods The study aims investigate, first-ever, antihyperlipidemic leaf hydroethanolic extract S. deserti, an endemic rare...

Natural products are reported to have a wide spectrum of pharmacological properties such as antimicrobial, anti-inflammatory and anti-cholinesterase. The genus Hypericum (Hypericaceae) is source variety molecules with different biological activities, notably hypericin various phenolics.The goals the present work were determination total phenolic flavonoid content, hyperforin concentration well evaluation humifusum L. (Hhu) perfoliatum (Hper).The extracts aerial parts powdered, then extracted...

The small amount of data regarding the antifungal activity Dittrichia viscosa (L.) Greuter against dermatophytes, Malassezia spp. and Aspergillus spp., associated with few comparative studies on antimicrobial methanolic, ethanolic, butanolic extracts underpins study herein presented. total condensed tannin (TCT), phenol (TPC), flavonoid (TFC), caffeoylquinic acid (CQC) content methanol, butanol, ethanol (80% 100%) D. were assessed their bactericidal fungicidal activities evaluated....

Mediterranean saltbush Atriplex halimus L. (Amaranthaceae) from different bioclimatic arid zones (ten wild populations) were studied. Phenols contents, flavonoids, flavonols, tannins and anthocyanins determined then tested for their antioxidants, antidiabetic anti-acetylcholinesterase (AChE) activities. Levels of total polyphenols including flavonoids high varied significantly among analyzed populations. Nine phenolic acids four identified the first time in methanolic fraction quantified by...

The composition of the fatty acids roots and aerial parts Aritolochia longa (Aristolacheae) Bryonia dioïca (Cucurbutaceae) was analyzed by gas chromatography (GC-FID) chromatography-mass spectrometry (GC-MS). oils extracted from both species were rich in polyunsaturated with essential linolenic linoleic being most prominent compounds. Oleic majors species. Whatever plant part species, saturated predominantly composed palmitic stearic acids. antibacterial activity, minimum inhibitory...

Abstract In this study, chemical composition and in vitro biological activities of artichoke by‐products (leaves, floral stems bracts) issued from two Tunisian varieties were evaluated. Analysis was performed by means high‐performance liquid chromatography with diode array detection coupled to electrospray ionization mass spectrometric (LC/DAD/ESI‐MS). Total phenolic (TPC) flavonoid (TFC) contents as well the antioxidant activity conducted three complementary methods, DPPH, ABTS FRAP tests,...

Dittrichia viscosa which belongs to the Asteraceae family is frequently used treat hematomas and skin disorders in Mediterranean herbal medicine. This study aims validate its antioxidant effects potential on healing wounds. The ethanolic extract of D. leaves was formulated as 2.5% 5% (w/w) ointment bases beeswax sesame oil. During this study, extract, ointments containing vehiculum were assessed for their total phenol content (TPC), caffeoylquinic acid (CQC), activities using complementary...

The present study describes the chemical composition of essential oil different plant parts Devrra tortuosa; in vivo and vitro biological activities extract oils. Apiol was found to be major component (between 65.73% 74.41%). best antioxidant were observed for flowers (IC50 = 175 μg/ml). samples stems roots exhibit lower activity 201 μg/ml 182 μg/ml, respectively). values IC50 showed that extracts methanol highest antioxidants 64.8 102 EOs excellent antifungal against yeasts with low azole...

Aloe vera L. is used largely in the pharmaceutical, cosmetic, and agro-food industries. The vitro technique was proposed as an alternative method for large-scale propagation and/or conservation breeding programmes response to increasing demand vera. Unfortunately, a major problem application of plant tissue culture browning cultured tissues microbial contamination. This work investigates first time efficacy using Essential Oils (EOs) control enzymatic contamination cultures from Murashige...

The essential oils of Daucus carota L. (Apiaceae) seeds sampled from ten wild populations spread over northern Tunisia were characterized by GC-FID and GC/MS analyses. In total, 36 compounds identified in the D. seed oils, with a predominance sesquiterpene hydrocarbons most samples (22.63-89.93% total oil composition). main volatile β-bisabolene (mean content 39.33%), sabinene (8.53%), geranyl acetate (7.12%), elemicin (6.26%). composition varied significantly across populations, even for...
