The green economy is a sustainable development tool based on the valorization of economic, natural and social resources. The FINNOVER project (“Innovative strategies for the development of cross-border green supply chains”) proposes a technical-economic path for the creation and development of new supply chains for the eco-sustainable extraction and use of natural bioactive compounds in phytotherapic, food, cosmetic, and phytopharmaceutical applications. Castanea spp. and their preparations have been widely used for hundreds of years all over the world. Different bioactive compounds (botanicals) are present in medicinal plants and derived-products as key components: all these molecules are quite variable in the plant material, according to genotype (intraspecific chemodiversity), different collection stages, pedoclimatic conditions of sampling sites (wild or cultivation zones), used agrotechniques, and post-harvest handling. This research was aimed to compare the bioactive compound pattern of Castanea spp. bud-preparations (herbal preparations derived from embryonic fresh plant tissues as buds and sprouts) with eco-sustainable extracts by herbal preparation processing waste. Molecules were extracted by the encoded traditional method (a cold maceration in a solution of 95% ethanol and glycerol), an innovative method (extracts with low organic solvent content), and by green extraction technologies (Pulsed Ultrasound Assisted Extraction – PUAE). HPLC methods were used to identify and quantify the main bioactive compounds, and to obtain a specific phytochemical profile. The established protocol was simple, sensitive and reliable and it could be used for the evaluation and quality control of natural products and relative eco-sustainable extracts.

Abstract
The green economy is a sustainable development tool based on the valorization of economic, natural and social resources. The FINNOVER project (“Innovative strategies for the development of cross-border green supply chains”) proposes a technical-economic path for the creation and development of new supply chains for the eco-sustainable extraction and use of natural bioactive compounds in phytotherapic, food, cosmetic, and phytopharmaceutical applications. Castanea spp. and their preparations have been widely used for hundreds of years all over the world. Different bioactive compounds (botanicals) are present in medicinal plants and derived-products as key components: all these molecules are quite variable in the plant material, according to genotype (intraspecific chemodiversity), different collection stages, pedoclimatic conditions of sampling sites (wild or cultivation zones), used agrotechniques, and post-harvest handling. This research was aimed to compare the bioactive compound pattern of Castanea spp. bud-preparations (herbal preparations derived from embryonic fresh plant tissues as buds and sprouts) with eco-sustainable extracts by herbal preparation processing waste. Molecules were extracted by the encoded traditional method (a cold maceration in a solution of 95% ethanol and glycerol), an innovative method (extracts with low organic solvent content), and by green extraction technologies (Pulsed Ultrasound Assisted Extraction – PUAE). HPLC methods were used to identify and quantify the main bioactive compounds, and to obtain a specific phytochemical profile. The established protocol was simple, sensitive and reliable and it could be used for the evaluation and quality control of natural products and relative eco-sustainable extracts.
