Background: Lipid based excipients have increased acceptance nowadays in the development of novel drug delivery systems in order to improve their pharmacokinetic profiles. Drugs encapsulated in lipids have enhanced stability due to the protection they experience in the lipid core of these nano-formulations. Phytosomes are newly discovered drug delivery systems and novel botanical formulation to produce lipophilic molecular complex which imparts stability, increases absorption and bioavailability of phytoconstituent. Curcumin, obtained from turmeric (Curcuma longa), has a wide range of biological activities. The poor solubility and wettability of curcumin are responsible for poor dissolution and this, in turn, results in poor bioavailability. To overcome these limitations, the curcumin-loaded nano phytosomes were developed to improve its physicochemical stability and bioavailability. Objective: The objective of the present research work was to develop nano-phytosomes of curcumin to improve its physicochemical stability and bioavailability. Methods: Curcumin-loaded nano phytosomes were prepared by using phospholipid Phospholipon 90 H using a modified solvent evaporation method. The developed curcumin nano phytosomes were evaluated by particle size analyzer and differential scanning calorimetry (DSC). Results: Results indicated that phytosomes prepared using curcumin and lipid in the ratio of 1:2 show good entrapment efficiency. The obtained curcumin phytosomes were spherical in shape with a size less than 100 nm. The prepared nano phytosomal formulation of curcumin showed promising potential as an antioxidant. Conclusion: The phytosomal complex showed sustained release of curcumin from vesicles. The sustained release of curcumin from phytosome may improve its absorption and lowers the elimination rate with an increase in bioavailability.

The genus Scorzonera comprises nearly 200 species, naturally occurring in Europe, Asia, and northern parts of Africa. Plants belonging to the Scorzonera genus have been a significant part of folk medicine in Asia, especially China, Mongolia, and Turkey for centuries. Therefore, they have become the subject of research regarding their phytochemical composition and biological activity. The aim of this review is to present and assess the phytochemical composition, and bioactive potential of species within the genus Scorzonera. Studies have shown the presence of many bioactive compounds like triterpenoids, sesquiterpenoids, flavonoids, or caffeic acid and quinic acid derivatives in extracts obtained from aerial and subaerial parts of the plants. The antioxidant and cytotoxic properties have been evaluated, together with the mechanism of anti-inflammatory, analgesic, and hepatoprotective activity. Scorzonera species have also been investigated for their activity against several bacteria and fungi strains. Despite mild cytotoxicity against cancer cell lines in vitro, the bioactive properties in wound healing therapy and the treatment of microbial infections might, in perspective, be the starting point for the research on Scorzonera species as active agents in medical products designed for miscellaneous skin conditions.

Hypericum Species

There are over 500 species in the Hypericum genus worldwide. Crude extracts from Hypericum species have been reported in folkloric medicine as analgesics, anthelmintics, astringents, antidepressants, diuretics, and anti-inflammatories. The current review aims to provide an in-depth analysis of local uses, pharmacological activities, and phytochemical composition of different extracts generated from Hypericum species. The review data was collected via literature search from Google, Google Scholar, Medline, Pubmed, Mendeley, Science Direct, Chemical Abstracts, Web of Science, and Scopus. The most studied of the entire Hypericum genus is H. perforatum, approved to manage mild depression. Other species that have been reported to have ethnomedicinal value are H. erectum, H. monogynum, H. attenuatum, H. japonicum, H. beanii, H. monantheum, H. wightianum, H. scabrum, H. monogynum, H. monogynum, H. geminiflorum, H. ascyron, H. seniawinii, H. elodeoides, H. petiolulatum, H. wightianum, H. hengshanense, H. japonicum, and H. revolutum. Over 900 phytochemicals have been isolated from the Hypericum genus plant species, mostly phenolics, and terpenoids. Studies have been carried out to validate the ethnopharmacological use of extracts from Hypericum species against depression, cancer, inflammation, and microbial infections. There are limited safety studies involving medicinal plants from the Hypericum genus; however,further investigations on toxic effects, phytochemical composition, and biological activities are necessary to validate the medicinal uses of plant species of the Hypericum genus empirically. The present article reviews ethnopharmacology, phytochemistry, and toxicology of the Hypericum genus, which several communities have used to treat various conditions.

Curcumin, a diarylheptanoids compound which isolated primary from Curcuma longa, exhibits a variety of exciting biological activities, including as an antibacterial agent. In the present study, a sulfanilamide-contained curcumin compound was synthesized and characterized to investigate the antibacterial activity against gram-positive bacteria S. aureus, B. subtilis and gram-negative bacteria E. coli. The characterization of the synthesized compound was determined by analysing peak absorbance, functional group, and molecular weight using mass spectroscopy, UV/Vis and FTIR spectrophotometry. Curcumin-sulfanilamide compound exhibited the best antibacterial activity against gram-negative bacteria compared to curcumin and the curcumin-derived compound containing isoxazole with inhibitory zone of 11 mm.
