Aerial parts of Inula montana were investigated for its sesquiterpenoid composition. Five sesquiterpene lactones, isoinuviscolide, gaillardin, 1beta-hydroxy-3beta-acetoxy-eudesm-4(15), 11(13)-dien-12-8beta-olide, pulchellin-C and pulchellin-E were identified for the first time in this plant. One of them, 1beta-hydroxy-3beta-acetoxy-eudesm-4(15),11(13)-dien-1 2-8beta-olide, is a novel natural pr...

Many VR applications require picking and moving of virtual objects. Many gesture based solutions do not work reliably, whereas controller based methods are not as natural as hand pose recognition. Tethered controllers add the issue of a cable being in the user’s way. We developed a gesture interface using a Leap Motion finger tracker attached to an Oculus Rift DK2 and implemented three ways of ...

In this study, three phenolic compounds were isolated from the seeds of Zizyphus spina-christi for the first time. The compounds were identified by means of 1 H-NMR-, UV and GC-MS as p-hydroxybenzoic acid, kaempferol, quercetin-3-O--L-rhamnosyl--D-glucopyranoside (rutin).

Ziziphus Mill. (Rhamnaceae) is comprised of about 170 species that are mainly distributed in tropical to subtropical regions, with few in the temperate zone. Several Ziziphus fruit tree species are important energy, nutrient, and medicinal resources for human populations, particularly for those living in rural regions. To date, limited genomic information is available for this genus. Here, we a...
