1 Radical scavenging activity of aaptamine derivatives : a theoretical study = Hoạt tính quét gốc tự do của các dẫn xuất aaptamine : nghiên cứu lý thuyết / Nguyen Thi Le Anh, Pham Thi My, Truong Dinh Hieu // Khoa học & Công nghệ Đại học Duy Tân .- 2025 .- No. 5(72) .- P. 57-67 .- 540

The Quantitative Structure-Activity Relationship (QSAR) reveals that the antioxidant properties (BDE and the Gibbs free energy of reaction of the HT mechanism) exhibit correlation with some key molecular aspects, such as ionization potential, the HOMO-LUMO gap, the absolute hardness and absolute electronegativity of the molecules.

2 Chemical composition of Premna serratifolia L. leaf essential oil growing in Vietnam = Thành phần hóa học tinh dầu lá của Premna serratifolia L. ở Việt Nam / Le Thi Mai Hoa, Vu Thi Hien, Vo Thanh Thuong, Le Thi Thanh Truc, Nguyen Thi Thuc, Prabodh Satyald, Bui Van Nguyen, Nguyen Huy Hung, William N. Setzer // .- 2024 .- Số 04(65) .- P. 163-169 .- 540

The essential oil extracted from the leaves of Premna serratifolia underwent hydrodistillation using a Clevenger-type apparatus and was subsequently subjected to analysis through gas chromatography coupled with mass spectrometry (GC/MS). The predominant compounds in the essential oil were those with sesquiterpene skeletons, in both hydrocarbon and oxygenated forms. Notable constituents included caryophyllene oxide, accounting for 23.4% of the oil, (E)-βcaryophyllene at 15.5%, as well as phytol (6.9%), α-copaene (5.5%), and δ-cadinene (4.4%).
