TL;DR: Three new triterpenoidal monodesmosides (1-3), together with two known saponins (7 and 8), were isolated from the fresh fruits of Ternstroemia japonica.
Abstract: Three new triterpenoidal monodesmosides (1-3) and three new triterpenoidal bisdesmosides (4-6), together with two known saponins (7 and 8), were isolated from the fresh fruits of Ternstroemia japonica. The structures of 1-6 (ternstroemiasides A-F) were elucidated on the basis of spectral analysis and chemical degradation.

TL;DR: The sedative compound was established as jacaranone (1), and its effect was clearly demonstrated through a dose-dependent response analysis, the first time that its sedative effect has been demonstrated.

TL;DR: Cheek et al. as mentioned in this paper described a new endangered cloudforest shrub with neotropical affinities from Kounounkan, Guinea, W Africa, which is confined to cloud (submontane) forest in galleries along watercourses.
Abstract: Ternstroemia guineensis is described from a sandstone table mountain at Kounounkan, possibly the last in the Fouta Djallon (Guinea Highlands) to remain largely unimpacted by humans and to have mainly intact natural habitats. It occurs about 2400 km westward of the nearest existing record (Nigeria) of the genus in Africa. It is confined to cloud (submontane) forest in galleries along watercourses. Its conservation status is assessed as Endangered using the IUCN 2012 criteria. The species differs from the other two African highland species, T. cameroonensis and T. polypetala, in having hermaphrodite flowers with a long subcylindric style and punctiform stigmas, and petals connate at the base into a tube (not dioecious, with a short style and cone-like stigmas, and free petals) resembling in these features the neotropical Ternstroemia species, as does also the lowland wetland T. africana of Nigeria, Gabon and Angola.

TL;DR: This work confirms the value of Ternstroemia sylvatica as an important anti-inflammatory and analgesic plant, whose mechanism seems to be associated to its antioxidant effects, and supports its uses in the Mexican traditional medicine.

TL;DR: Six new phenylethanoid glucosides, ternstrosides A-F (1-6), a new kaempferol derivative (7), and eight known compounds were isolated from the fresh leaves of Ternstroemia japonica, showing potent antioxidative activity in three different tests.
Abstract: Six new phenylethanoid glucosides, ternstrosides A-F (1-6), a new kaempferol derivative (7), and eight known compounds were isolated from the fresh leaves of Ternstroemia japonica The structures were elucidated by 1D and 2D NMR spectroscopic analyses Compounds 1-7 showed potent antioxidative activity in three different tests, with IC50 values in the range 326-650 microM in the hydroxyl radical (*OH) inhibitory activity test, 3329-8221 microM in the total ROS (reactive oxygen species) inhibitory activity test, and 114-1353 microM in the peroxynitrite (ONOO-) scavenging activity test
