What are the morphological characteristics of this plant?
Phellodendroon amurense has woody, climbing stems that produce large, simple, opposite leaves with ovate to elliptical shapes and serrated margins. The foliage typically measures several centimeters in length and features prominent venation on the underside of the blades. These plants often develop a scrambling habit, using their stems to ascend through surrounding vegetation in forest understories. The reproductive structures consist of small, inconspicuous flowers that eventually develop into fleshy berries. These morphological traits allow the species to thrive in temperate and subtropical woodland environments.
What is the geographical distribution of this plant?
This plant is native to East Asia, specifically occurring in parts of China, Korea, Japan, and the Russian Far East. It typically thrives in temperate forest environments where moisture levels are consistent. Within these regions, it is often found growing in shaded areas under dense forest canopies. Its range extends from the subtropical zones of southern China toward the more northern, colder climates of the Amur region. This widespread distribution allows it to occupy various ecological niches across the northeastern Asian continent.
What parts of this plant are used medicinally?
Phellodendroon amurensse contains medicinal compounds primarily extracted from its bark and leaves. The bark is frequently harvested to obtain chemical constituents that serve various therapeutic purposes in traditional practices. Additionally, the leaves are utilized in decoctions to address specific health ailments. These botanical parts are processed to harness their bioactive properties for medicinal applications. Researchers often study these components to understand their potential pharmacological effects.
What are the pharmacological activities of Phellodendron amurense?
This plant has demonstrated significant pharmacological activities including anti-inflammatory, antioxidant, antibacterial, antifungal, and antimicrobial properties. Research indicates that its chemical constituents effectively combat oxidative stress by neutralizing free radicals within biological systems. These bioactive compounds also exhibit potent inhibitory effects against various pathogenic bacteria and fungi.

These diverse biological capabilities highlight its potential utility in both traditional medicine and modern pharmacology.
As discussed in a study, Phellodendri Amurensis cortex (PAC) is a traditional Chinese herb used to treat various liver and kidney sickness and possesses good anti-inflammatory efficacy. In studies involving rat models established with 6.5 mg/kg doxorubicin injections for five weeks, PAC treatment notably decreased urinary protein, serum Cr content, and renal tissue lesions while increasing serum TP and ALB content. When administered once a day at doses of 216, 432, and 864 mg/kg, PAC demonstrated the ability to recall metabolite levels. Specifically, the high-dose group recalled 18 metabolites, the medium-dose group recalled 13 metabolites, and the low-dose group recalled 8 metabolites. These metabolites were involved in nine primary metabolic pathways, including steroid hormone biosynthesis and alanine, aspartate and glutamate metabolism. Ultimately, PAC possesses a renoprotective effect against doxorubicin-induced nephritis by improving renal function and regulating key enzymes.
What medicinal compounds this plant contains?
This plant contains the medicinal compounds berberine, jatrorrhizin, palmatine, magnoflorine, and quercetin. These specific alkaloids and flavonoids work together to provide various pharmacological benefits to the human body. Berberine and palmatine are well-known for their potent antimicrobial and anti-inflammatory properties. The presence of jatrorrhizin and magnoflorine further enhances the plant's biological activity against different pathogens. Additionally, the antioxidant capabilities of quercetin contribute to the overall therapeutic profile of these chemical constituents.
As discussed in a study, Phellodendroon amurense bark contains both alkaloid and non-alkaloid fractions. The non-alkaloid fraction of this plant extract contains limonoids such as limonin and obakunone, which suppress nitric oxide production with IC50 values of 16 and 2.6 μM, respectively. Additionally, the plant contains alkaloids like berbermin which displayed an IC50 value of 12 μM. These constituents contribute to the anti-inflammatory effects of the Phellodendri Cortex extract.
What health problems is this plant used for?
This plant is used for treating inflammation, skin disorders, urinary tract infections, liver sickness, and gastritis. Its bioactive compounds work to soothe the digestive lining to alleviate symptoms of gastritis. The plant also possesses properties that help combat various skin disorders through topical or systemic application. It serves as a natural remedy for managing urinary tract infections by supporting the renal system. Additionally, it is utilized to support hepatic functions and mitigate the effects of liver sickness.
What are the herbal preparations of this plant?
This plant can be prepared as a decoction of its bark to treat various ailments such as malaria, dysentery, and skin infections. The bark is typically boiled in water for an extended period to extract its active medicinal compounds. Practitioners often use these liquid extracts to alleviate inflammation and reduce fevers. Some traditional applications also involve using the plant material in topical applications for wound healing. These preparations rely on the specific chemical properties found within the woody tissues of the species.
