Kudzu (Pueraria species) is a perennial plant within the Fabaceae family, native to China, Japan, and India. It is known for its therapeutic properties, mainly due to its high content of isoflavones, including puerarin, daidzein, daidzin, genistein, and genistin. These isoflavones are found throughout the plant and are important in developing pharmaceutical drugs. This review comprehensively analyzes naturally occurring isoflavones in Kudzu, focusing on advanced and green techniques for their extraction, purification, and identification. Additionally, it highlights their health benefits and the growing demand in the global food and pharmaceutical industries. Due to their superior efficiency, scalability, and cost-effectiveness, contemporary eco-friendly extraction methods like ultrasound, microwave, enzyme-assisted, and supercritical fluid extraction are gaining prominence in this endeavor. They are crucial in optimizing the extraction process, driving innovation within industries, and harnessing natural sources, ultimately boosting global economies. Scientific studies confirm that Kudzu isoflavones have various anti-diabetic, neuroprotective, anti-cancer, antioxidant, alcohol detoxification, and cardiovascular protective effects. This review encourages further exploration of Kudzu isoflavones as a nutritional food source. It also highlights advancements in extraction methods within pharmaceuticals and natural products, underscoring the superiority of modern techniques over conventional ones. Additionally, critical analysis of the trends, limitations, and scope of Kudzu-extracted isoflavones for novel food applications can further advance scientific understanding.

Objective: The study investigated effects of peony callus extracts (PCE) on the protective efficacy against Ultraviolet B (UVB)-induced photoageing, using in vitro and in vivo studies. The research focused on PCE's ability to protect against inflammatory factors, DNA damage and accumulation of senescent cells, along with the evaluation of the extract's potential anti-photoageing benefits to skin.

Methods: Human keratinocyte cell line (HaCaT cells), mast cells and fibroblasts were used to evaluate the role of PCE in anti-photoageing.

Jiangsu Co-Innovation Centre of Efficient Processing and Utilization of Forest Resources, Jiangsu Key Lab for the Chemistry and Utilization of Agro-Forest Biomass, College of Chemical Engineering, Nanjing Forestry University, Nanjing, China.

Introduction: Pine needles are a rich source of bioactive compounds, and there are few reports on the extraction and identification of active substances in various types of pine needles.

Objectives: The objective of this study is to enhance the efficiency and yield of pine needle essential oil extraction by employing an innovative ultrasonic-assisted salt-out hydrodistillation technology. It also aims to establish a correlation between gas chromatography-mass spectrometry (GC-MS) and electronic nose (E-nose) to distinguish essential oils from Cedrus deodara, Pinus thunbergii, Pinus massoniana, and Pinus koraiensis.
