Article Abstract

One new alkaloid consanguine B (1), together with 10 known alkaloids (2-11), were isolated from ethanol extract of the branches and leaves of Polyalthia obliqua Hook.f. & Thomson collected in the Hainan Province, China. Their structures were elucidated by the detailed analysis of comprehensive spectroscopic data. All compounds were evaluated for their cytotoxic activities. Compound 1 showed weak cytotoxic activities against Hela and MCF-7 human cancer cell lines.

Plant phenotypes exhibit high plasticity, with shoot branching as a prime example and a key factor influencing yield in many species. The availability of photosynthates is a critical determinant of shoot branching (or tillering in monocots). Carbohydrates, primarily in the form of sucrose, are synthesised in actively photosynthetic leaves (sources) and transported to non-photosynthetic tissues (sinks), such as tiller buds.
