TL;DR: The stem-bark of Dalbergia sissoo has yielded, besides the known compounds dalbergenone, dalbergin and methyl dalBERgin, a new 4-phenyl chromene, Dalbergichromene as discussed by the authors.

TL;DR: In this article, a large number of natural essentially non-terpenoid compounds contain isoprene units, which can undergo a number of modifications giving rise to types of compounds listed below under (A) to (F) in increasing order of complexity.

TL;DR: The leaves of Parkinsonia aculeata have been found to contain three C-glycosides as mentioned in this paper, which can be separated by fractional crystallization after preliminary lead salt purification, but preparative paper chromatography was found effective for the separation of all three.

TL;DR: From the seeds of Pongamia glabra, pongaglabrone, a new furano-flavone has been isolated and its structure established as 3',4'-methylenedioxy-furano-(2″:3″-7:8)-FLAVO as discussed by the authors.

TL;DR: In this article, the reaction of β-resacetophenone with 2-methyl-but-3-en-2-ol in the presence of boron trifluoride-etherate at room temperature is found to yield a mixture of three separable 5-C-prenyl-(40%), 3-Cptenyl-(25%) and 3,5-di-C-, 3-Prenyl-, 15%) resacetophenones.
