Health Preservation Based on Biodiversity

Indonesia is one of the world’s megadiverse countries, possessing the greatest wealth of biological resources. Its tropical geographical conditions, supported by a warm climate and high rainfall, mean Indonesia is home to thousands of plant species with potential as medicine. Various types of these plants have been used by communities for generations as traditional medicinal ingredients, passed down through local wisdom. In the development of modern science, the use of medicinal plants is no longer based solely on empirical experience but is also studied through a phytochemical approach to identify the active compounds they contain (Harborne, 1998). Phytochemistry is a branch of science that studies natural chemical compounds produced by plants, especially secondary metabolites such as alkaloids, flavonoids, saponins, tannins, terpenoids, steroids, glycosides, and phenolics. These compounds function as a plant’s defence mechanism against attacks by microorganisms, insects, and environmental stress. For humans, these secondary metabolites have various beneficial biological activities, such as antioxidant, antimicrobial, anticancer, anti-inflammatory, antidiabetic, antiviral, and immunomodulatory properties (Cowan, 1999). The potential of Indonesian medicinal plants is enormous, as the country is estimated to have more than 30,000 plant species, of which around 9,600 species are known to have medicinal properties. However, only a small fraction has been scientifically studied, both in terms of their phytochemical content and pharmacological activity (Ministry of Health of the Republic of Indonesia, 2017). This condition indicates that Indonesia still has a very wide opportunity to develop research based on natural resources as raw materials for modern medicines and phytopharmaceuticals. Various medicinal plants growing in Indonesia have been proven to contain important bioactive compounds. Turmeric, for example, contains curcumin which has anti-inflammatory and antioxidant activities and the potential to inhibit the growth of cancer cells. Javanese turmeric is rich in xanthorrhizol and curcuminoids, which function to improve liver health and the immune system. Ginger contains gingerol and shogaol, which are effective as antioxidants and anti-inflammatories and help overcome digestive disorders. Similarly, king of bitters contains andrographolide, which has antiviral and immunomodulatory activities that are widely researched in the pharmaceutical field (WHO, 2013). Besides plants that are already widely known to the public, Indonesia also has various endemic plants that have the potential to be sources of new bioactive compounds. Research on local flora continues to develop to discover secondary metabolites that have the potential to become new drug candidates. This exploration process is very important considering the increasing cases of antimicrobial resistance, the emergence of new diseases, and the need for safer, naturally derived medicinal ingredients. In phytochemical studies, the identification of secondary metabolite content is carried out through several stages, starting from extraction using specific solvents, qualitative phytochemical tests, separation of compounds using chromatography, to identification of molecular structures using spectroscopy such as UV-Vis, FTIR, NMR, and GC-MS. This scientific approach allows researchers to understand the relationship between the chemical structure of a compound and its biological activity so that it can be developed into standardised herbal medicines and phytopharmaceuticals (Harborne, 1998). The advantage of medicinal plants as a source of phytochemicals lies not only in the content of their active compounds but also in the synergistic effect among various secondary metabolite components. In many cases, the combination of several active compounds can produce a better therapeutic effect than the use of a single compound. Therefore, research on the interactions between phytochemical compounds is a continuously developing field in modern pharmacology. The use of medicinal plants also has high economic value. The industries of jamu, standardised herbal medicine, natural cosmetics, and functional foods are growing along with increasing public awareness of a healthy lifestyle. Indonesia has a great opportunity to become the world’s centre for the herbal industry if supported by scientific research, sustainable cultivation of medicinal plants, and government policies that favour the development of products based on local resources. Standardisation of quality, safety, and efficacy is a key requirement for Indonesian herbal products to compete in the international market (BPOM RI, 2022). On the other hand, biodiversity conservation is an important factor in maintaining the sustainability of phytochemical sources. Excessive exploitation of medicinal plants without being balanced with conservation efforts can lead to population decline and even the extinction of certain species. Therefore, conservation through cultivation, germplasm banks, conservation areas, and the empowerment of local communities is an inseparable part of the strategy for developing Indonesian medicinal plants. The local wisdom of indigenous communities also plays a vital role in the conservation and use of medicinal plants. Knowledge about plant types, processing methods, dosage, and disease indications has been passed down for hundreds of years and serves as an initial source of information for various modern phytochemical studies. The ethnopharmacological approach, which combines modern science with traditional knowledge, has proven capable of accelerating the discovery of new drug candidates from natural ingredients. The development of chemical analysis technology, molecular biology, and bioinformatics further strengthens phytochemical research on Indonesian medicinal plants. Through a multidisciplinary approach, bioactive compounds can be mapped.
