Herbal Technological Prospects of Morus nigra L.: A Systematic Patent Analysis Review.

Abstract

Background: Morus nigra L. is a plant with significant potential for drug development due to the presence of numerous bioactive compounds in its various parts.

Objectives: This article aims to compile the technological perspectives of Morus nigra L. towards drug development and therapeutic indications based on registered patents in databases.

Methods: The study analyzed patents published within the last five years, focusing on products derived from different parts of the Morus nigra L. plant. Patent databases such as the European Patent Office (EPO), the United States Patent and Trademark Office (USPTO), the World Intellectual Property Organization (WIPO), and the National Institute of Industrial Property Databases (INPI) were examined.

Results: A total of 45 patents were categorized by country of origin, type of applicant, extraction method, and therapeutic indications. China had the highest number of patent filings (43.48%), and private companies were the primary technology patent holders (38.64%). Noteworthy extraction methods included ultrasound-assisted extraction, decoction, infusion, and maceration. The most utilized plant parts were leaves (44.44%), followed by fruits (35.56%), root bark (15.56%), and stems (4.44%). The main therapeutic indications identified were the treatment of hyperglycemia and dyslipidemia (43.33%), along with digestive problems, cosmetics, nutrition, and cleaning applications.

Conclusion: The study of patents covers discoveries and advancements often absent in scientific articles, making a review focused on this advanced information crucial for expanding existing scientific knowledge. Even if some therapies have been explored previously, patents can reveal innovative approaches and fresh perspectives that contribute to sustained scientific progress.
