The invention discloses an SSR primer combination for cedrela sinensis genetic diversity detection and application of the SSR primer combination. The SSR primer combination contains 13 pairs of SSR primer pairs which are used for carrying out specific amplification on SSR sites TS01-TS013 in the DNA (Deoxyribose Nucleic Acid) of the Toona sinense genome of the toona sinensis; the SSR primer combination is applied to cedrela sinensis genetic diversity detection, cedrela sinensis core germplasm population construction or cedrela sinensis variety identification. The SSR primer combination provided by the invention can accurately and efficiently detect the genetic diversity of the cedrela sinensis, provides a powerful tool for constructing a cedrela sinensis core germplasm population, and lays a solid foundation for long-term breeding and resource management of the cedrela sinensis.

The application discloses a synergistic bactericidal composition, comprising the following components: a toona sinensis extract: 16-2048 mu g / mL; a macrolide antibiotic: 0.0625-4096 mu g / mL; the bacteria are staphylococcus aureus or methicillin-resistant staphylococcus aureus, and the macrolide antibiotic is erythromycin or azithromycin. The application further discloses a use of the synergistic bactericidal composition in preparation of a medicine for treating skin and soft tissue infections. The composition provided by the application can convert the traditional macrolide antibiotics such as erythromycin and azithromycin which only have a bacteriostatic effect into a preparation which has clear bactericidal activity on staphylococcus aureus and drug-resistant strains thereof. After the toona sinensis extract is combined with the antibiotic, a synergistic effect is exhibited, and the concentration of the toona sinensis extract and the antibiotic required when the toona sinensis extract and the antibiotic are used alone can be greatly reduced.

This invention relates to a traditional Chinese medicine composition for treating chronic cervicitis complicated with HPV infection. The composition is made from the following raw materials in parts by weight: 26-34 parts raw Astragalus membranaceus, 26-34 parts Smilax glabra, 11-19 parts Toona sinensis root bark, and 26-34 parts raw Coix lacryma-jobi. This invention also provides the uses of the traditional Chinese medicine composition. In this invention, raw Astragalus membranaceus is the principal ingredient, tonifying Qi and strengthening the body's resistance; Smilax glabra and Toona sinensis root bark clear heat and dry dampness; and raw Coix lacryma-jobi dispels dampness and promotes tissue regeneration, serving as assistant ingredients; the entire formula works synergistically to strengthen the body's resistance, eliminate pathogenic factors, and promote tissue regeneration.

The present application belongs to the field of biotechnology, and provides a method for inducing transgenic hairy roots of Toona sinensis. The present application successfully uses Agrobacterium rhizogenes transformation for the first time to induce transgenic hairy roots of Toona sinensis, directly observes the efficiency of the transgenic hairy roots through the red RUBY gene and the GUS reporter gene carried by the vector, and calculates the transformation efficiency to be more than 90% according to the strains. The uvGFP gene with a strong green fluorescent signal is successfully transformed, and can be used for the verification and screening of the transgenic hairy roots. The transgenic Toona sinensis tissue is obtained under non-tissue culture conditions, the operation process is simple, the technology is simple, the cost is low, the efficiency is high, the complete transgenic plant can be further generated through the transgenic hairy roots, and the difficulty in the verification of the gene function of Toona sinensis is overcome.

The invention provides a female external nursing product with antibacterial, anti-inflammatory and antipruritic effects and a preparation method thereof, and relates to the technical field of biological medicine nursing products. The invention provides an external nursing product for women, which is prepared from the following pure traditional Chinese medicinal materials: cortex ailanthi, saururus chinensis, pericarpium granati, chingma abutilon seeds, red halloysite, lysimachia clethroides, gynura plicata, evodia lepta leaves, peach leaves, pine needles, water gossypium, solanum lyratum and cyrtomium fortunei as raw materials. The traditional Chinese medicine raw materials in the product are scientific in compatibility and have a synergistic effect, the product shows an ultra-excellent antibacterial effect on staphylococcus aureus, escherichia coli and candida albicans, meanwhile, the product has good anti-inflammatory and anti-inflammatory effects, can achieve rapid itching relieving, and in addition, the product has no stimulation effect on vaginal mucosa of female white rabbits and has good safety. The product disclosed by the invention can be used for effectively improving the symptoms such as itching and causalgia, peculiar smell and abnormal secretion caused by colpitis mycotica, bacterial vaginitis, trichomonas vaginitis, senile vaginitis and the like.

The invention relates to the technical field of cigarette perfuming, in particular to a cedrela sinensis extract for cigarette perfuming and a preparation method of the cedrela sinensis extract. The preparation method comprises the following steps: performing supercritical carbon dioxide extraction on a cedrela sinensis raw material to obtain a cedrela sinensis crude extract; separating the crude extract by adopting preparative liquid chromatography, and performing segmented collection according to an elution time window to obtain a plurality of fractions to be selected; and respectively adding the to-be-selected fractions into the cigarettes for sensory evaluation, screening out the to-be-selected fractions capable of improving the sensory quality of the cigarettes as target fractions, and taking the target fractions as the toona sinensis extract for cigarette perfuming. The method successfully makes a positive contribution to the cigarette aroma, can bring components which are in a fluffy and fine smoke state and are low in irritation and clean in aftertaste, the components are enriched in specific fractions, and the inherent defect of direct application of the crude extract is overcome.
