Background Ziziphus jujuba Mill. cv. ‘LingwuChangzao’ is a traditional jujube cultivar in northwest China. It is of great significance to explore the weed community composition and environmental characterization for the ecological control and comprehensive management of weeds in jujube orchards. In this article, a total of 37 species were recorded in 40 sample plots (1 m × 1 m). Moreover, fourteen environmental indicators to characterize the spatial locations, climate and soil nutrient characteristics of the plant communities were adopted. Methodology Through the two-way indicator species analysis (TWINSPAN) quantity classification and canonical correspondence analysis (CCA) ranking methods, the types of weed communities in the main planting base of jujube ‘LingwuChangzao’ and the main environmental factors affecting the change and distribution of weed types were analyzed. Results The weed communities within the study area were divided into 15 types by the TWINSPAN classification. There were significant differences in soil factors to the species diversity indices of the weed communities, the diversity of weed communities was negatively correlated with available potassium, whereas positively correlated with soil water content. The CCA results showed that community structure and spatial distribution of weed communities were affected by soil water content, total potassium, soil organic carbon, total phosphorus, total nitrogen. Our results can be used as a reference for orchard weed management and provide a theoretical basis for weed invasion control and creating a higher biodiversity in arable land under the background of environmental change.

The invention relates to a method for obtaining robinin-7-O-glucuronide through extraction and separation from Dracocephalum moldavica. The method is characterized by comprising the following steps: smashing the dry overground part of the Dracocephalum moldavica, obtaining a percolating solution through collection and extraction by adopting a percolating method, and obtaining a thick extract through vacuum concentration; and obtaining extract powder after water-bath drying. The extract powder is stirred by adopting a dry method after being dissolved with high concentration alcohol, polyamide column and ODS column chromatography is carried out, and after elution, an eluant is evaporated to dryness to obtain a white crystal, namely compound robinin-7-O-glucuronide, through a reduced pressure distillation device.

Preparation method of robinin-7-O-glucuronide

The invention discloses application of robinin-7-O-glucuronide. A compound has cardioprotective effect activity, so that the robinin-7-O-glucuronide can be used as a lead compound with a cardioprotective effect.
