Polyphenols, flavonoids and condensed tannins contents, as well as the antioxidant activity of the ethanolic and aqueous extracts obtained from aerial parts of 10 wild Tunisian plants, have been determined. Extracts showed appreciable levels of polyphenols and flavonoids, which reached 215.16 mg GAE
This research investigates the synthesis and characterization of gold nanoparticles from Periploca hydaspidis and their antimicrobial and anti oxidant activity. The synthesis of AuNPs was confirmed by UV-Vis spectrophotometer and structure by a high resolution atomic force microscope. X-ray
A total of five components (Catechin, Caffeic acid, Ferulic acid, Rosmarinic acid, and Amentoflavone) were identified in Periploca angustifolia leaf methanolic extract. This extract did not cause any cytotoxic effect on HepG2 cell line within the range of concentrations tested (0-400 µg mL-1). Thus,
A novel water-soluble polysaccharide named PLP1 was successfully isolated from root barks of Periploca laevigata by hot water extraction and further purified by DEAE-sepharose chromatography. PLP1 has a relative molar mass of 5.57 105 g/mol determined by Ultra-high performance liquid
The extraction of Periploca polysaccharides (PAPS) was optimized using the response surface methodology. The influence of solvent, liquid-solid ratio and extraction time on polysaccharide yield was evaluated using a full factorial design (23). Also, PAPS extract did not induce a cytotoxic effect on
The root bark essential oil of Periploca sepium Bunge (Asclepiadaceae/ Apocynaceae) obtained by hydrodistillation was investigated by GC and GC-MS. 2-Hydroxy-4-methoxybenzaldehyde was found to be the main component (78.8% of the total) among 17 identified compounds. 2-Hydroxy-4-methoxybenzaldehyde

Context. Many diseases are associated with oxidative stress caused by free radicals. Objective. The present study evaluated the in vitro antioxidant and antibacterial activities of various extracts of aerial parts of Periploca aphylla and Ricinus communis. Materials and Methods. In vitro antioxidant

Two new tetrahydrofuran-type lignans, (-)-gentioluteol 9-O-β-d-glucopyranoside (1), (-)-berchemol 9-O-β-d-apiofuranosyl-(1→6)-O-β-d-glucopyranoside (2), along with sixteen known compounds 3 - 18 were isolated from the 95% EtOH extract of the stems of Periploca forrestii. The structures of the new
Periploca angustifolia has numerous biological properties and also used against various diseases. In our study, this plant has been used for biotechnological production of polysaccharides. The prevention action of polysaccharides isolated from P. angustifolia (PAPS) against Cd-caused oxidative
A preparative separation method using macroporous absorptive resin coupled with high-performance liquid chromatography (HPLC) was developed for the separation of six fractions of an 80% ethanol extract of Periploca forrestii Schltr. The six obtained 5-95% ethanol fractions (A, B, C, D, E, and F)
The present study describes the synthesis, characterization of nano-particles from Periploca hyaspidis and their in vitro biological activity. The synthesis of AgNPs was confirmed by UV-Vis spectrophotometer and structure by atomic force microscope. The crystallite size and different functional
Drought resistance and recovery ability are two important requisites for plant adaptation to drought environments. Proline (Pro) metabolism has been a major concern in plant drought tolerance. However, roles of Pro metabolism in plant recovery ability from severe drought stress are largely

Taking two-year-old Periploca sepium seedlings as test materials, an experiment with controlled soil water contents was conducted to study the effects of repeated drying and re-watering on the leaf photosynthetic characteristics and the lipid peroxidation and antioxidant system in young leaves,
The nano-encapsulation of Periploca angustifolia phenolic extract using the macrocyclic carbohydrate polymers (β‑cyclodextrins) is a most approach compared with other encapsulation methods. In this work, the β‑Cyclodextrins-PAE complex stability has been evaluated by advanced analytical methods and
