What are the morphological characteristics of this plant?

Actinidia polygama has woody, perennial vines characterized by alternate, simple, ovate leaves that possess serrated margins and long petioles. The foliage is typically dark green with prominent venation and can grow several meters in length as it climbs through forest undergrowth. During the flowering season, small, white, fragrant flowers emerge from the leaf axils in clusters. These blossoms transition into small, fleshy, globose berries that turn from green to a translucent white or yellowish color when ripe. The plant's overall structure relies on these flexible stems to navigate its temperate woodland habitat.

What are the herbal preparations of this plant?

This plant is used to create various medicinal herbal preparations including water-soluble extracts, decoctions, and tinctures. These preparations are often derived from the dried leaves or stems to harness their bioactive compounds. Water-soluble extracts are particularly common because they efficiently pull out the beneficial polyphenols and antioxidants from the plant material. Practitioners frequently utilize these liquid forms to facilitate easier absorption within the digestive system. Such preparations are studied for their potential therapeutic properties in traditional medicine.

According to a study published by "BioFactors (Oxford, England)", the research examined the radical scavenging activity of traditional Japanese herbs, including matatabi (Actinidia polygama). The water-soluble components of the herb were extracted in boiling water, while the volatile oil was extracted via a distillation apparatus or by steeping in organic solvents like petroleum ether and ethyl ether. The radical scavenging activity was determined by measuring the decrease of DPPH free radicals at 517 nm using both a colorimetric assay and the HPLC method.

The main herbal preparations of this plant are shown in the list below.

  • water-soluble extracts
