Ethanol extract from the aerial parts of L. as well as the latex of the plant suspended in water are used by the Brazilian population for the treatment of various diseases, including cancer. The purposes of this study were to determine if the ethanol extract is effective as cytotoxic agent against gastric adenocarcinoma cells (AGS) and its chemical composition by GC-MS, ESI-(-)-FT-ICR MS and (-)-ESI-LTQ-MS/MS. The results were compared with that of latex previously described by us. Hexane and aqueous fractions showed higher cytotoxicity on AGS cells. Nine triterpene compounds were detected by GC-MS in hexane fraction, including euphol and friedelin, while ellagic acid was identified as main phenolic compound in aqueous extract. Therefore, the greater cytotoxic activity of the ethanol extract of the aerial parts of for gastric cancer, when compared to latex, seems to originate from the antiproliferative effects of ellagic acid and triterpenes.

is known for its potential antioxidant and anti-inflammatory properties, attributed to triterpenes, flavonoids, and tannins. This study aimed to optimise the extraction process for aerial parts of using vortex extraction. A Box-Behnken experimental design coupled with response surface methodology was employed to evaluate the effects of three independent variables: sample-to-solvent ratio, velocity, and temperature.

Quaternary ammonium salts (QAs) are a class of highly active compounds widely used in medicine and agriculture. However, many QAs lack a conjugated system, making their recognition and quantitation challenging. Stachydrine is a representative unconjugated QA with a high content in Houtt.

In this study, screening of the collected 70 Salvia nemorosa L. populations from 54 habitats from West Azerbaijan province, Iran was evaluated by analyzing the content of phytochemical compounds, antioxidant activity, and UHPLC-HRMS profiling in different populations. The aerial parts of the plants were analyzed based on total phenolic (TPC) and flavonoid (TFC), total tannin (TTC), ascorbic acid (AAC), chlorophylls (Cla, and Clb), total carotenoid (TCC), β-carotene, antioxidant activity (by DPPH and FRAP assays), and 40 polyphenolic compounds by UHPLC-HRMS (phenolic acids, flavonoids and fatty acyl glicosides).

A novel adaptive model-based motion control method for multi-UAV communication relay is proposed, which aims at improving the networks connectivity and the communications performance among a fleet of ground unmanned vehicles. The method addresses the challenge of relay UAVs motion control through joint consideration with unknown multi-user mobility, environmental effects on channel characteristics, unavailable angle-of-arrival data of received signals, and coordination among multiple UAVs. The method consists of two parts: (1) Network connectivity is constructed and communication performance index is defined using the minimum spanning tree in graph theory, which considers both the communication link between ground node and UAV, and the communication link between ground nodes.
