This invention belongs to the field of pharmaceutical technology, specifically relating to a temperature- and pH-responsive ocular hydrogel loaded with isosorbide nanomicelles, its preparation method, and its applications. This invention is the first to apply the traditional Chinese medicine ingredient ISO to the treatment of cataracts, and innovatively designs a complete ocular delivery formulation for it. This invention not only pioneers a new application field for ISO in ophthalmic treatment, but more importantly, by constructing a "nanomicelle-smart gel" composite platform, it systematically solves the three fundamental technical challenges faced by ISO in ocular applications: poor solubility, low corneal permeability, and short retention time on the ocular surface, thereby transforming its potential pharmacological activity into actual ocular therapeutic efficacy. Therefore, this invention has significant clinical implications and broad market prospects.

To provide a novel material derived from natural products that is effective in promoting the expression of the PGC-1α gene or the like.SOLUTION: Provided is a food composition or pharmaceutical composition for promoting expression of the PGC-1α gene in myotube cells or in skeletal muscle, which contains isoorientin and at least one of 3-o-caffeoylquinic acid and 5-o-caffeoylquinic acid.SELECTED DRAWING: Figure 2

The invention discloses application of two small molecular substances in regulation and control of weed suppression activity of flavonoid glycoside substances. The invention provides any one of the following applications of a GST activator and a GST inhibitor: (A1) regulating the inhibition activity of wheat flavone-5-O-glucoside to weeds; and (A2) the inhibition activity of the isoorientin on weeds is regulated. According to the invention, the weed suppression effect of the flavonoid glycoside substances can be obviously improved, and the use of chemical pesticides is reduced, so that a novel biological control method is provided for agricultural production, and green agriculture and sustainable development can be realized.

The invention relates to the technical field of traditional Chinese medicine detection, in particular to a method for identifying species of fructus viticis and application of the method. When 1.5, the fructus viticis is single-leaf fructus viticis; when the ratio is gt; when 2.0, the fructus viticis is the three-leaf fructus viticis; when the ratio is between 1.5 and 2.0, it is determined that the sample is mixed or abnormal, the content determination method of the isoorientin and vitexin in the indexes is provided in detail, the precision, the stability and the repeatability of the method are good, and the average sample adding recovery rate is 80%-120%; through chemical verification, the identification accuracy reaches 100%, and the index has extremely high specificity on single-leaf fructus viticis; the ratio intervals of the pure single-leaf and three-leaf chastetree fruits are not overlapped, the critical value is clear, and cross misjudgment is avoided, so that the distinguishing degree of the identification index is extremely high, the ratio calculation result is stable, abnormal discrete data is avoided, and the objectivity and reliability of a verification conclusion are ensured.
