What are the morphological characteristics of this plant?
Actinidia valvata has woody, climbing vines characterized by large, cordate to broadly ovate leaves with entire or slightly wavy margins and a distinctively thick, leathery texture. The stems are flexible and utilize tendrils to ascend through forest canopies. Its flowers are typically solitary and emerge from the leaf axils, displaying white petals and numerous prominent stamens. The fruit develops into a globose berry that transitions from green to a dark, purplish color when fully ripe. These morphological traits allow the plant to thrive in shaded, moist environments.
What is the geographical distribution of this plant?
This plant is native to the temperate forest regions of East Asia, specifically spanning across China, Japan, Korea, and parts of Russia. It typically flourishes in mountainous areas where the terrain provides ample shade and moisture. These habitats often consist of deciduous or mixed forests located at various elevations. The species prefers the cool, humid environments found within these specific subtropical and temperate zones. Its distribution is closely tied to the presence of suitable soil conditions found in these eastern latitudes.
How is this plant cultivated?
This plant, commonly known as mountain kiwi, requires well-drained, organic-rich soil and a temperate climate with distinct seasonal changes for successful cultivation.
It is a vigorous woody vine that thrives in partial shade to protect its foliage from intense direct sunlight. Regular moisture is essential during the growing season, though the root system must never remain waterlogged to prevent rot. Proper pruning is necessary to manage its sprawling growth habit and to encourage the production of fruit.
Once established, the vine requires a sturdy trellis system to support its heavy weight as it climbs.
What parts of this plant are used medicinally?
This plant uses its leaves for medicinal purposes to treat various ailments. These leaves are often harvested and processed to create decoctions or topical applications. They are frequently utilized in traditional medicine to reduce inflammation and fever. Some practitioners also employ the foliage to address digestive issues or skin irritations. The specific chemical compounds found within the leaf tissue provide these therapeutic benefits.
According to a study published by "Journal of separation science", the leaves of Actinidia valvata Dunn are used as a famous Chinese medicinal herb. Researchers investigated 12 kinds of macroporous resins to separate flavonoid triglycosides from these leaves. The HPD-300 resin was selected for the first cleaning-up process using 20% ethanol to remove undesired constituents and 60% ethanol to elute the targets. A solvent system composed of ethyl acetate-n-butanol-water in ratios of 2:1:3 and 4:1:5, v/v was used for purification. This process yielded three flavonoid triglycosides with purities of all over 95% as determined by the HPLC area normalization method.

According to a study published by "Pharmaceuatical biology", Actinidia valvata Dunn (Actinidiaceae) is recognized as a well-known traditional Chinese medicine. A triterpenoid saponin isolated from this plant is 2a,-3a,-24-Trihydroxyurs-12-en-28-oic acid (TEO), which is a corosolic acid analogue. In experiments involving three human hepatocellular carcinoma cell lines, TEO was tested at various concentrations from 2.5 to 40 μg/mL. After 24 h of treatment, the IC50 values for BEL-7402, BEL-7404, and SMMC-7721 cells were 34.6, 30.8, and 30.5 μg/mL, respectively. Furthermore, treating the three cell lines with 40 μg/mL of TEO increased the G1 phase by more than 21%.

According to a study published by "Pharmaceutical biology", the triterpenoid saponin TEO isolated from Actinidia valvata Dunn exhibits anti-proliferation and apoptosis-inducing effects on three human hepatocellular carcinoma cell lines. When treated for 24 h at various concentrations from 2.5 to 40 μg/mL, TEO showed IC50 values of 34.6 μg/mL for BEL-7402, 30.8 μg/mL for BEL-7404, and 30.5 μg/mL for SMMC-7721. Treatment with 40 μg/mL of TEO increased the G1 phase by more than 21% and caused DNA damage and morphological changes. The substance also declines mitochondrial membrane potential and activates TNF-α as well as caspase-3, caspase-8, and caspase-9. These proapoptotic effects are mediated through the mitochondrial pathway and changes in Bcl-2, Bax, and Bid protein expressions.
