Summary: This study investigated the memory-enhancing properties of Lavandula Stoechas L. The active fraction AfL.s of the plant showed improvement in memory retention behavior in mice and positive effects on biochemical parameters in the brain. However, high doses of AfL.s resulted in hyperactivity and death in mice.

Summary: In this study, the most efficient solvent system for extracting ursolic acid from lavender was found to be methanol-dichloromethane (1 : 1, v/v), with a yield of 2.22 g/100 g plant sample. A new practical method for isolating ursolic acid from polar extracts was also demonstrated for the first time. The extracts and ursolic acid showed strong inhibition of α-glycosidase activity, making them potential herbal sources for controlling postprandial blood sugar levels and preventing diabetes.

Summary: This paper revises the typification of the name Lavandula viridis (Labiatae). A holotype previously identified by Upson and Andrews from a specimen at the herbarium BM is found to consist of multiple elements. Therefore, a lectotype is designated according to the Shenzhen Code of 2018, using a specimen collected by Francis Masson in Madeira in 1776 and preserved at BM.

Summary: Rosemary, an important aromatic species in the Mediterranean basin, is a source of natural bioactive compounds. However, the lack of selection and standardized material leads to variability in the essential oil composition. This study monitored the essential oil composition of Spanish rosemary populations and found that the variability is mainly controlled by genetics.

Summary: The most abundant volatile compounds in sweet wormwood essential oil are artemisia ketone and trans-caryophyllene, while the major compounds in the hydrosol are camphor, 1,8-cineole, and artemisia ketone. Sweet wormwood essential oil can be classified into four chemotypes: artemisia ketone+artemisia alcohol, artemisia ketone, camphor, and nonspecific. The high content of camphor, 1,8-cineole, and artemisia ketone in sweet wormwood hydrosol makes it a potential substitute in various industries.

Summary: The evaluation of the elemental content of moringa leaves and flowers revealed that they are a good source of macro and micronutrients, as well as important polyunsaturated fatty acids. The flowers contain a significant amount of soluble sugars. The essential oils extracted from different parts of the moringa plant are mainly composed of alkanes and fatty acids. Further studies will determine if the consumption of moringa can address nutritional imbalances and prevent hypertension and diabetes.

Summary: This study aimed to characterize the secretory structures of the endemic aromatic Asteraceae plant Santolina impressa, analyze its essential oil from the aerial organs, and evaluate its antiviral activity against herpes simplex viruses HSV-1 and HSV-2. The study found that Santolina impressa secreted an oleoresin and a resin rich in flavonoids through biseriate glandular trichomes and secretory ducts. The essential oil of Santolina impressa mainly consisted of monoterpenes, with β-pinene and β-phellandrene as the major components. The essential oil exhibited dose-dependent inhibition of HSV-1 and HSV-2 infections in Vero cells.

Summary: Control of pine wilt disease caused by the pinewood nematode (PWN) can be achieved by trunk injection of nematicides. Essential oils (EOs) are potential alternatives due to their biodegradability and low toxicity. This study evaluated the toxicity of EOs and their mixtures against PWN and compared them with a commercial nematicide. The results showed that certain EO mixtures exhibited high activities against PWN, with low toxicity to mammals and potential for environmental degradation.
