The Peruvian Amazon is one of the richest ecosystems in plant-based bioactive compounds, including essential oils, resins, carotenoids, and latex. These substances, in addition to their ecological functions in plants, have applied value in medicine, cosmetics, and the food industry. Inspired by the contributions of *Plants Producing Essences, Resins, and Their Derivatives* (Mas-Guindal, 1944), the El Perezoso Botanical Garden in Chanchamayo seeks to translate this knowledge into an accessible science education and outreach program for the community, strengthening the link between Amazonian tradition, applied science, and biodiversity conservation.
The study of plant essences and resins is not new. In the mid-20th century, the work of Joaquín and Ascensión Mas-Guindal systematized knowledge about the production, extraction, and quality control of these compounds (Mas-Guindal, 1944). However, much of that knowledge remained confined to technical manuals and laboratories. Today, the El Perezoso Botanical Garden is taking on the challenge of bringing this science to the Amazonian countryside and making it accessible to communities, visitors, and students.
The proposal revolves around a central question: How can a botanical garden become a space for the generation and dissemination of applied science for the benefit of the community?
The El Perezoso Botanical Garden boasts over five hectares of Amazon rainforest in Chanchamayo, Junín region. The collection includes emblematic species that produce oils, resins, or secondary metabolites of interest:
These species allow us to demonstrate in the field the processes described in the book: formation of metabolites, storage in secretory organs, artisanal extraction and purity analysis.
The Garden has designed educational modules where visitors identify aromas, textures and flavors of different plants, understanding that behind each sensation there is a natural chemical compound (flavonoids, terpenes, carotenoids).
Inspired by the recommendations of Mas-Guindal (1944), community workshops are being conducted to identify adulterated essential oils, differentiating pure products from commercial blends. This contribution is key to building a green economy based on trust and quality.
The message is reinforced that secondary metabolites fulfill vital ecological functions: attracting pollinators, defending against pests, and storing energy. Thus, conserving the Aguaje fruit not only means preserving a fruit, but also protecting a source of carotenoids that support both human health and Amazonian biodiversity.
Among the most representative Amazonian species for understanding the importance of secondary metabolites, the Dragon's Blood (Croton lechleri) stands out. Its reddish latex, known and used since pre-Columbian times, is rich in alkaloids and phenolic compounds such as taspine and proanthocyanidins, recognized for their healing, anti-inflammatory, and antiviral properties. From a scientific perspective, Dragon's Blood exemplifies what has been described in classic studies on resins and latex: complex substances that fulfill a defensive function in the plant and, at the same time, offer humanity valuable therapeutic potential. For the El Perezoso Botanical Garden, this species constitutes an ideal bridge between tradition and science, as it demonstrates how an Amazonian natural resource can be studied, validated, and applied for the benefit of public health and conservation.
The El Perezoso Botanical Garden demonstrates that a conservation space can transcend its role as a living collection to become a scientific laboratory open to the community. By integrating Amazonian ethnobotanical tradition with the science of essential oils and resins, the Garden contributes to the development of a more informed, conscious society capable of valuing natural resources sustainably.
This model can be replicated in other botanical gardens and reserves, strengthening the Amazon's role as a source of scientific and cultural knowledge for the world.
