Application of plant extracts cosmetics in the field of anti-aging

Skin aging is a direct manifestation of body aging,representing a complex and irreversible natural process,which is influenced by genetics,lifestyle and environmental factors.In the process of skin aging,the skin epidermis gradually become thinner,the inherent repair ability gradually weakens,the collagen and elastin gradually decrease and the skin gradually loses elasticity.Although skin aging is inevitable,it can be delayed to some extent by using cosmetics.Natural extract cosmetics are highly favored by consumers for their safety and efficacy,aligning with consumer preferences for natural,organic,efficient and sustainable skincare concepts.Numerous plant resources in nature possess superior properties like moisturizing,barrier repair,anti-oxidation,sunscreen whitening and anti-inflammatory properties after thousands of years of natural selection.These properties enable plant components to effectively enhance the anti-aging effects of skincare products through multiple anti-aging pathways,which can be widely used to develop natural anti-aging skin care products.

Strengthening research in the conservation and utilization of plant germplasm resources is of significant value and importance. In this study, the present status of conservation, utilization, and existing problems of plant germplasm resources in China and around the world were reviewed; further, through analyzing measures taken by global countries for plant germplasm resources protection, countermeasures for plant germplasm resources conservation in China were also presented from three aspects, namely, collection and conservation, information network construction and national legislation and policies.

Study on the Current Situation and Protection Countermeasures of Wild Plant Resources in Xishuangbanna National Nature Reserve

[Objective] The aim was to study the current situation and protection countermeasures of wild plant resources in Xishuangbanna National Nature Reserve. [Method] The current situation of wild plant resources in Xishuangbanna National Nature Reserve was researched by means of route survey, sample plot survey and literature survey, and then the main impact factors of wild plant resources were analyzed by using participatory rural appraisal and problem tree analysis, finally protection countermeasures were put forward according to current situation and main impact factors. [Result] There were 2 779 species of vascular plants belonging to 214 families and 1 012 genera (including subfamilies and varieties) in Xishuangbanna National Nature Reserve, among them, there existed 261 species of pteridophyte belonging to 41 families and 91 genera, 14 species of gymnosperm belonging to 6 families and 6 genera, and 2 504 species of angiosperm belonging to 167 families and 915 genera. Wild plant resources in reserve were mainly affected by planting under forest, habitat fragmentation, cutting trees, collection and utilization of no-timber products, development of animal husbandry, insufficient recognition of community residents to reserve management establishment and lots of floating population. In the future, wild plant resources in reserve could be protected through strengthening propaganda, education and management, enforcing the law strictly and other countermeasures. [Conclusion] The study could provide theoretical foundation for the protection of wild plant resources in Xishuangbanna National Nature Reserve.
