A phytochemical investigation into the bark of Erythrophleum fordii yielded four new compounds, two new cassaine diterpenoids (erythrofordin T and U, 1 and 2) and two new cassaine diterpenoid amines (erythroformine A and B, 6 and 7), as well as nine known compounds. We report for the first time the isolation of erythrofordin V (3) from a natural source and(More)

The paper presents a research on storing and utilizing energy collected from the movement of vehicles on road. This energy can be collected by a series of friction plates which are positioned on the road surface. Capacity of this potential energy is then recycled for public usage such as traffic signals, street lights, advertisement broads, etc. Energy(More)
Detailed phytochemical investigation from the root bark of Morus alba resulted in the isolation of eleven new compounds, including seven 2-arylbenzofuran derivatives (morusalfurans A-G), three flavonoids (morusalnols A-C), and one geranylated stilbene (morusibene A), as well as 22 known compounds. The structures of the identified compounds were elucidated(More)
