The directional extraction process comprises the following steps: taking a monkshood raw material, crushing the monkshood raw material, and sequentially carrying out water extraction, resin enrichment, silica gel column chromatography purification, sephadex refining and HPLC (High Performance Liquid Chromatography) separation, so as to obtain the pyrazine heart-strengthening component in the monkshood; the pyrazine heart strengthening component in the radix aconiti lateralis praeparata is radix aconiti lateralis praeparata pyrazine A and / or radix aconiti lateralis praeparata pyrazine B; the structure of the monkshood pyrazine A is shown in the specification; the structure of the monkshood pyrazine B is shown in the specification. The directional extraction process of the pyrazine heart-strengthening components in the radix aconiti carmichaeli is established for the first time, efficient separation of toxic components and impurities is achieved through stepped multi-step purification of water extraction, macroporous resin enrichment, silica gel purification, gel refining and preparative HPLC separation, and efficient directional extraction of the pyrazine heart-strengthening components can be achieved; the purity of the obtained pyrazine heart-strengthening component is greater than or equal to 98%, and the problem that the components of the product extracted by the traditional process are mixed is solved.

The invention provides an anti-aging composition for reducing periorbital wrinkles and a preparation method and application thereof, and relates to the technical field of cosmetics, the anti-aging composition for reducing periorbital wrinkles comprises the following components: a Xiaoji lotus bulb extract solution, an Aconitum carmichaeli leaf and cowpea seed extract compound and an arginine / lysine polypeptide solution, and optionally an adenosine and optionally an ascorbic acid polypeptide solution. According to the anti-wrinkle eye cream disclosed by the invention, the summering snow lotus bulb extract, the aconite leaf and cowpea seed extract and the arginine / lysine polypeptide have a synergistic effect, so that a multi-target anti-wrinkle mechanism from inhibiting muscle contraction and promoting structure repair to instant soothing is formed, and the problem of coexistence of dynamic wrinkles and static wrinkles of periorbital skin is effectively solved.

The utility model relates to medicinal plant seedling raising equipment technical field discloses a kind of drip irrigation type aconitum neriifolium seedling raising device, including outer frame assembly, transfusion subassembly and drip irrigation subassembly.Transfusion subassembly is transported nutrient solution by water pump and pipeline, the rotating ring of drip irrigation subassembly can adjust drip irrigation angle, the vortex fan and cleaning plate of drop opening subassembly can prevent blockage, and the light supplementing lamp of outer frame assembly provides illumination.The device can accurately drip irrigation and adapt aconitum neriifolium growth, improve seedling raising effect, adapt the root system range of different growth stages of aconitum neriifolium seedling, compared with traditional fixed drip irrigation water saving, nutrient solution utilization rate is improved, with the automatic cleaning of inner wall impurity change flow, compared with existing device, reduce the blockage rate, reduce artificial cleaning working hours.

This invention belongs to the field of biotechnology, providing a VIGS silencing system for the AgPDS gene in *Aconitum carmichaelii*, its construction method, and its application. It is a method for constructing a transient gene silencing system for *Aconitum carmichaelii* based on VIGS technology, and the constructed silencing system has been validated through application. The results show that this silencing system can significantly reduce the expression level of the AgPDS gene in *Aconitum carmichaelii* leaves, with a plant silencing rate of 70.83%. This invention utilizes a combination of leaf injection and soil drenching infection methods. The *Aconitum carmichaelii* AgPDS gene silencing system constructed using tobacco brittle virus (TRV) can be systematically disseminated within *Aconitum carmichaelii* plants, effectively reducing the expression level of the *Aconitum carmichaelii* AgPDS gene, resulting in chlorophyll bleaching. The gene silencing system of this invention is simple, rapid, and efficient, providing strong support for the biosynthesis analysis of medicinal components in *Aconitum* plants and related research on molecular breeding for genetic improvement.
