TL;DR: Callicarpnoids A-C (1-3), three new ent-clerodane diterpenoid dimers formed via a [4 + 2] hetero Diels-Alder cycloaddition, appeared as a third example of this type of dimers, were isolated from the stems of Callicarpa arborea Roxb by comprehensive spectroscopic analysis.

TL;DR: In this paper, the isopimarane diterpenoid derivatives (1-7) with a structure formula represented by formula I, pharmaceutical compositions containing pharmaceutical carriers and isopimaraned derivative as active components, a preparation method of the isipimarane derivatives and the pharmaceutical compositions, and applications of these derivatives in preparation of drugs used for treating human diseases, especially in preparation for treating estrogen mediated diseases, and asestrogen biosynthesis conditioning agents.

TL;DR: In this paper , six new sesquiterpenoids, named as ainslides A−F (1−6), including one carotene-type sesQUERPene (1), one eudesmane (2), four guaianolides (3, 6, 7, 14), together with eight known sesQuerpenoids (7, 14) were purified from the whole plants of Ainsliaea pertyoides.

TL;DR: In this article , 14 undescribed seco-type diterpenoids, named nudifloids A-N, together with ten known analogs, were isolated from the leaves of Callicarpa nudiflora.

TL;DR: A rectangular core few-mode fiber is designed and experimentally demonatrate that can support the transmission of TE/TM/TE/TM modes with ultra-low differential group delays.
