In China, the fruits of these shrubs are a delicacy, and their skins, rich in saponins and flavonoids; are used in folk medicine. The natural range of occurrence of Akebia quinata and Decaisnea insignis is in East Asia, and the earliest mention of their cultivation in Europe dates back to 1945. Fully ripe fruits for the study were collected in September and October. The determinations included the size, color, reflactance and chemical composition (fresh berries-soluble solids, titratable acidity, pH, total polyphenol, L-ascorbic acid, nitrates and nitrites; frozen berries-phenolics and mineral composition) of fruits harvested from shrubs grown in Szczecin and in the Arboretum in Glinna near Szczecin. In the climatic conditions of Szczecin, these species can flourish and produce ripe fruit. Akebia quinata bears significantly heavier fruits (72.1 g) than Decaisnea insignis fruits (31 g), despite similar length of fruits from both species. The fruits of Decaisnea insignis are more acidic (0.72 g 100 mL-1) and have a higher content of polyphenols (567 mg 100 mL-1), while the ones of Akebia quinata contain more extract (16.8%) and L-ascorbic acid (37.5 mg 100 mL-1).

Gut Microbiota and Metabolome Response of Decaisnea insignis Seed Oil on Metabolism Disorder Induced by Excess Alcohol Consumption

“…D. insignis possesses racemes of strikingly deep purplish-blue elongated fruits and is a wild resource plant food with delicacy, which has also been used in traditional Chinese medicine as an antirheumatic and antitussive drug for a long time. , Interestingly, D. insignis seed oil (DISO) has been found to contain large amounts of monounsaturated fatty acids (MUFAs), mainly including palmitic acid (C16:1, n = 7) and oleic acid (C18:1, n = 9).…”

Meanwhile, mounting evidence has demonstrated that palmitoleic acid supplementation can improve the metabolic function of the fatty liver by PPARα-dependent AMPK activation, 13 and oleic acid regulates hepatic lipogenesis through a liver X receptor-dependent signaling.…”

The Akebia Genus as a Novel Forest Crop: A Review of Its Genetic Resources, Nutritional Components, Biosynthesis, and Biological Studies

“…These compounds have various biological and pharmacological activities, such as antimicrobial activity, diuretic action, and promotion of cholesterol metabolism (Hostettmann and Marston, 1995 ; Vincken et al, 2007 ; Thimmappa et al, 2014 ). In Akebia plants specifically, triterpene saponins, one of the most diverse compounds, accumulate in high concentrations in the stems, fruits, and seeds (Ochmian et al, 2014 ; Liu et al, 2018 ). The triterpene aglycones of Akebia plants include oleanlic acid, norarjunolic acid, arjunolic acid, and hederagenin ( Figure 2 ).…”

Akebia fruit: A review on its extraction, phytochemicals, bioactivities and applications

“…Akebia fruit consists of three parts: the pulp, the pericarp, and the seeds (Figure 1). The pulp of Akebia fruit will gradually soften during ripening (Ochmian et al, 2014). Studies have shown that the softening process of the pulp of Akebia fruit may be related to the levels of some pectic enzymes and a great quantity of proteins involved in plant hormones, stress, and defense responses (Juan et al, 2021).…”
