Gas chromatography with mass spectrometry (GC/MS) and fractionation steps were used to determine the sterol patterns of red goji berries in detail. Twenty-five sterols were detected in fresh berries of two species (Lycium barbarum and L. chinense) from bushes grown in the botanical garden of the University of Hohenheim, and 20 sterols were identified. The rarely occurring campesta-5,24(25)-dienol, β-sitosterol, Δ5-avenasterol, campesterol, and cycloartenol represented >60 % of the total sterol content. Maturity and drying of fresh red goji berries caused small changes but did not affect the characteristic sterol pattern. This was confirmed by analyzing various commercial dried red goji berry samples from different sources. Separated flesh and seed samples revealed pronounced differences in the sterol pattern. A new method of merging GC/MS chromatograms showed that ∼75 % of the sterols were present in seeds and ∼25 % in flesh. The unique sterol profile may be exploited to authenticate red goji berries.

Combining near-earth remote sensing spectral imaging technology with unmanned aerial vehicle (UAV) remote sensing sensing technology, we measured the Ningqi No. 10 goji variety under conditions of health, infestation by psyllids, and infestation by gall mites in Shizuishan City, Ningxia Hui Autonomous Region. The results indicate that the red and near-infrared spectral bands are particularly sensitive for detecting pest and disease conditions in goji.

Goji berries are a small-fruited shrub with industrial importance whose fruit considered beneficial in both fresh and dried forms. Current germplasms of goji berries include small fruits with a short shelf life, less sweet and bitter taste, and a lack of appropriate genetic information. This study aimed to employ whole genome resequencing to generate an ultra-dense bin linkage map and to elucidate the genetic basis of goji fruit quality and size using quantitative trait loci (QTL) mapping analysis in a cross-pollinated hybrid population.
