What are the morphological characteristics of this plant?
Derris robusta has a woody climbing vine habit characterized by large, compound leaves and clusters of fragrant, pea-like flowers. The foliage typically consists of trifoliate leaflets that are elliptic or ovate in shape with smooth margins. Its stems are robust and capable of twisting around host trees to reach higher light levels in the forest canopy. The inflorescence emerges in dense racemes, displaying colors that range from pale yellow to creamy white. Small, legume-like pods develop from the flowers once pollination is complete.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of Southeast Asia, including countries such as Thailand, Malaysia, Indonesia, and parts of India. It typically thrives in moist, lowland areas where dense forest canopies provide necessary shade. The species is commonly found growing along riverbanks and in humid rainforest environments. Its distribution is closely tied to the availability of high rainfall and consistent warm temperatures characteristic of these equatorial zones. These specific environmental conditions allow the woody climber to spread effectively across its natural range.
How is this plant cultivated?
This plant, known as Derris robusta, is cultivated primarily as a climbing woody vine in tropical and subtropical regions to extract rotenone from its roots for use as a natural insecticide.
Growers typically plant the species in well-drained, moist soils that receive ample sunlight to encourage vigorous climbing growth. Because it is a legume, the cultivation process often benefits from nitrogen-fixing bacteria in the soil which supports rapid development. Maintenance requires regular watering and support structures such as trellises to allow the heavy vines to sprawl upward.
Once the plant reaches maturity, the roots are carefully harvested and processed to isolate the bioactive compounds.
What parts of this plant are used medicinally?
This plant provides medicinal value through the use of its roots, leaves, and twigs. The roots are most famously known for containing rotenone, which is utilized in various traditional treatments and as a natural pesticide. Extracts from the leaves are also applied in certain herbal remedies to address specific ailments. Even the woody twig can be processed for its chemical properties in traditional medicinal practices. These different components offer a diverse range of bioactive compounds for healing purposes.
According to a study published by "Phytochemistry", the twig extract of Derris robusta (DC.) Benth. was used to isolate twelve isoflavones. These compounds included three previously undescribed isoflavones, derrisrobustones A-C, and one previously undescribed natural isoflavone, derrisrubsone D, along with eight known isoflavones. The study evaluated these compounds for their alpha-glucosidase inhibitory activity. Among the isolated substances, derrisubone displayed the best alpha-glucosidase inhibitory activity. This activity was measured with an IC50 value of 64.2 uM.

What traditional systems uses this plant?
This plant, known commonly as derris, has been historically utilized by various Southeast Asian communities as a natural insecticide to control mosquito and lice populations.
The roots contain the potent chemical compound rotenone, which was traditionally crushed and steeped in water to create a poisonous liquid bath. This liquid was applied to skin or used to soak clothing to repel biting insects and kill parasites. Beyond pest control, some cultures historically used the extracted powder as a fishing aid to stun fish in small ponds.
These traditional practices demonstrate a long-standing reliance on the plant's biochemical properties for practical household and subsistence needs.
What are the pharmacological activities of Derris robusta?
This plant has potent pharmacological activities including significant α-glucosidase inhibitory activity, antioxidant properties, and antimicrobial effects. The inhibition of α-glucosidase suggests that extracts from Derris robusta may assist in managing blood glucose levels in diabetic models. Additionally, the plant contains various secondary metabolites that contribute to its ability to neutralize free radicals. These bioactive compounds also demonstrate effectiveness against various bacterial strains, highlighting its potential as a natural therapeutic agent. Research continues into how these specific chemical constituents interact with biological targets to improve human health.
According to a study published by "Phytochemistry", the twig extract of Derris robusta (DC.) Benth. yielded three previously undescribed isoflavones, derrisrumbustones A-C, and one previously undescribed natural isoflavone, derrisrumbustone D, in addition to 8 known isoflavones. These isolated compounds were evaluated for their alpha-glucosidase inhibitory activity. Among the evaluated compounds, derrisrobustone B had its (1″R, 2″R) absolute configuration established by single-crystal X-ray crystallography using Cu Kα radiation. The compound derrisrobustone displayed the best alpha-glucosidase inhibitory activity. This specific activity was measured with an IC50 value of 64.2 μM.

What medicinal compounds this plant contains?
This plant contains the rotenone-type isoflavonoid rotenone, which serves as its primary medicinal and bioactive compound. This specific chemical is a potent mitochondrial inhibitor that disrupts cellular energy production in target organisms. Beyond its insecticidal properties, research explores its potential applications in treating various metabolic and neurological conditions. The compound is derived from the roots and stems of the plant through specialized extraction processes. Scientists continue to study its structural characteristics to develop more refined pharmaceutical derivatives.
What health conditions is this plant used for?
This plant is used for managing blood glucose levels through its α-glucosidase inhibitory activity. This specific enzymatic inhibition helps slow down the digestion of carbohydrates in the digestive tract. By regulating the rate of sugar absorption, the plant may assist in preventing rapid spikes in blood sugar after meals. This biological mechanism is primarily focused on the metabolic processes related to glucose regulation. Consequently, the medicinal value of Derris robusta in this context is centered on its potential impact on glycemic control.
According to a study published by "Phytochemistry", the twig extract of Derris robusta (DC.) Benth. was analyzed for its isoflavones. Researchers isolated 3 previously undescribed isoflavones, derrisrumbustones A-C, and 1 previously undescribed natural isoflavone, derrisrubsone D, along with 8 known isoflavones. These compounds were evaluated specifically for their alpha-glucosidase inhibitory activity. Among the isolated substances, derrubone displayed the best alpha-glucosidase inhibitory activity. This specific activity was measured with an IC50 value of 64.2 uM.

What side effects this plant can have?
This plant can cause severe rotenone toxicity, which manifests through symptoms such as nausea, vomiting, abdominal pain, dizziness, headache, muscle weakness, hypotension, respiratory distress, and convulsions. Exposure to the chemical compounds within the plant disrupts cellular respiration, leading to significant physiological distress. These toxic effects can range from mild gastrointestinal discomfort to life-threatening neurological and respiratory failure. Because the rotenone acts as a potent metabolic poison, the onset of these symptoms can occur rapidly following ingestion or skin contact. Monitoring for these specific signs is critical when accidental exposure to the plant is suspected.
