Background: Nanoemulsions are promising drug delivery systems for topical application owing to the high transdermal penetration.
Objective: Due to the side effects of existing anti-inflammatory drugs, much attention has been paid to natural products such as flavonoids. The aim of this work was to formulate luteolin nanoemulsion (LNE) and to evaluate its anti-inflammatory effect.
Methods: LNE was prepared using the low-energy spontaneous emulsion method and characterized by transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy and dynamic light scattering (DLS). The anti-inflammatory effect of LNE was assessed in formalin and acetic acid-induced inflammation methods (Whittle test). Treatment with LNE (i.p, 4 consecutive days, 40 mg/kg) was compared with diclofenac 25 mg/kg and normal saline. In the formalin test, data were recorded at 1, 2 and 4 hours after formalin injection and in the Wittle test, the extent of Evans blue leakage in the peritoneal cavity was considered as vascular permeability.
Results: Formalin-induced edema decreased in the LNE group, but this reduction was not significant (p > 0.05), however, in Whittle test, both LNE and diclofenac significantly reduced Evans blue leakage compared with the group treated with acetic acid alone (p < 0.05).
Conclusion: Our results confirm the anti-inflammatory effect of LNE and give up a new platform for the design and development of bio-based carriers for more successful drug delivery.

Walnut husk extract (WHE) and pomegranate peel extract (PPE) were produced through ultrasound-assisted extraction. Total phenol, flavonoid and tannin contents (TPC, TFC and TTC), antioxidant and antimicrobial activities were determined. The best extracts were used for production of alginate (Alg) and chitosan (CS)-coated nanoemulsions containing WHE (NWHE) or PPE (NPPE).

Introduction: Luteolin (LUT), a naturally occurring flavonoid found in vegetables, fruits, and herbal medicines, has been extensively studied for its pharmacological activities, including anti-proliferative and anticancer effects on various cancer lines. It also exhibits potent antioxidant properties and pro-apoptotic activities against human cancers. However, its therapeutic potential is hindered by its poor solubility in water (5 μg/ml at 45°C) and low bioavailability.

Ethnopharmacological Relevance: The species Jatropha gossypiifolia, popularly known as "pinhão-roxo", is distributed throughout Brazil, is commonly employed for topical or oral administration in treating wounds, inflammations, and snake bites. Given the significant impact of snakebites on public health and the limitations of antivenom, coupled with the diverse molecular composition of this plant species, investigating its healing and antidermonecrotic capacities is relevant.
Aim Of The Study: This study aimed to develop a topical nanoemulsion incorporating the hydroethanolic extract of J.

Current pharmaceutical research is energetically excavating the pharmacotherapeutic role of herb-derived ingredients in multiple malignancies' targeting. Luteolin is one of the major phytochemical components that exist in various traditional Chinese medicine or medical herbs. Mounting evidence reveals that this phytoconstituent endows prominent therapeutic actions on diverse malignancies, with the underlying mechanisms, combined medication strategy, and pharmacokinetics elusive.
