What are the morphological characteristics of this plant?
Derris trifoliata has a climbing habit characterized by woody stems that use tendrils to ascend surrounding vegetation. The leaves are typically trifoliate, meaning they are composed of three distinct leaflets that are often ovate or elliptical in shape. These leaflets possess smooth margins and can vary in size depending on the age and environment of the plant. The plant produces small, fragrant flowers that are usually arranged in dense clusters or racemes. Its root system is adapted to provide stability for its sprawling, climbing growth pattern.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of Southeast Asia, spanning countries such as Thailand, Malaysia, Indonesia, and Vietnam. It is frequently found inhabiting coastal areas and low-lying riverbanks where moisture is abundant. The species thrives in humid environments characterized by seasonal rainfall and warm temperatures. Its distribution follows the maritime boundaries of the Indo-Malayan realm, often appearing in mangrove ecosystems. Because it prefers wet soil, its presence is highly concentrated along the edges of tropical wetlands.
How is this plant cultivated?
This plant, Derris trifolia, is cultivated as a perennial climbing vine in tropical and subtropical regions by planting seeds or cuttings in well-drained, moist, and fertile soils.
It thrives in humid environments with consistent sunlight and requires regular watering to maintain its vigorous growth habit. Growers often provide support structures like trellises or fences to accommodate its natural tendency to climb. Once established, the plant can be used both for its ornamental foliage and for the extraction of rotenone from its roots.
Careful monitoring for soil moisture levels is essential to prevent root rot in heavier clay compositions.
What parts of this plant are used medicinally?
This plant uses its leaves for medicinal purposes, specifically to treat skin conditions and various ailments. These leaves contain bioactive compounds that can be processed into traditional remedies. They are often applied topically to soothe inflammation or used in infusions for internal healing. Such applications rely on the chemical properties found within the foliage of the species. This practice highlights the importance of the plant's vegetative parts in local ethnobotany.
According to a study published by "Journal of natural medicines", the leaves of the Okinawan Leguminosae plant Derris trifoliata Lour. were utilized. From the leaves of Derris trifoliata collected in Okinawa, 15 glycosidic compounds were isolated and identified.

What traditional systems uses this plant?
This plant, known scientifically as Derris trifolia, has been traditionally harvested and used by various indigenous cultures across Southeast Asia and the Pacific Islands as a potent natural insecticide.
The roots contain high concentrations of rotenone, a chemical compound that acts as a powerful neurotoxin to fish and insects. Historically, people would crush the roots and release them into stagnant water to stun fish for easier collection. In many coastal communities, this method served as a primary means of gathering protein from local ecosystems.
Beyond fishing, the plant's extracts were also applied to clothing and stored goods to protect them from pest infestations.
What are the pharmacological activities of Derris trifoliata?
This plant has significant pharmacological activities including antimicrobial, antioxidant, anti-inflammatory, and insecticidal properties derived from its bioactive secondary metabolites. Research indicates that extracts from the plant can effectively inhibit the growth of various pathogenic bacteria and fungi. The presence of specific phytochemicals allows it to neutralize free radicals, which contributes to its potential antioxidant benefits. Additionally, its natural chemical composition makes it a candidate for developing organic pesticides to control insect populations. These diverse biological effects suggest that the plant holds promise for both medicinal and agricultural applications.
What medicinal compounds this plant contains?
This plant contains the medicinal compounds 12a-hydroxy rotenone, 12alpha-hydroxyrot-2'-enoic acid, dehurodeguelin, dehydrorotenone, and tephrosin. These specific phytochemicals are secondary metabolites often studied for their potential biological activities. Among these constituents, the rotenoids are frequently investigated for their insecticidal and antiparasitic properties. The presence of tephrosin further contributes to the diverse chemical profile found within the species. Researchers continue to analyze these molecules to understand their full pharmacological potential in human health.
According to a study published by "Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials", five rotenoids were isolated from the aerial parts of Derris trifoliata. These specific medicinal compounds are named dehydrodeguelin, dehydrorotenone, 12a-hydroxy rotenone, tephrosin, and 12alphabeta-hydroxyrot-2'-enoic acid. All 5 of these compounds were isolated from Derris trifoliata for the first time.
The primary medicinal compounds of this plant are shown in the list below.
- 12a-hydroxy rotenone
- 12alphabeta-hydroxyrot-2'-enoic acid
- dehydrodeguelin
- dehydrorotenone
- tephrosin
