What are the morphological characteristics of this plant?
Quassia indica has a woody, deciduous shrub or small tree morphology characterized by pinnately compound leaves, fragrant yellow flowers, and small, oblong, reddish-brown fruits. The leaves are typically arranged alternately and consist of several pairs of leaflets that are ovate to lanceolate in shape. Its stems are straight and can reach heights of up to several meters, often exhibiting a somewhat spreading crown. The inflorescence is composed of small, fragrant, bright yellow blossoms that emerge in clusters. Once pollinated, the plant produces small drupes that contribute to its reproductive cycle.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of Southeast Asia, spanning across countries such as India, China, Indonesia, Malaysia, and Thailand. It thrives primarily in the humid, low-lying areas of the Indo-Malayan botanical realm. Within these territories, the species is often found growing in moist, well-drained soils near riverbanks or in seasonally flooded forests. Its distribution is closely tied to specific climatic conditions that provide consistent warmth and high rainfall. Because it relies on these tropical environments, the plant does not extend into temperate or arid zones.
How is this plant cultivated?
This plant, Quassia indica, thrives in tropical environments with well-drained, fertile soil and requires consistent moisture and high humidity to flourish.
It is typically grown as a large shrub or small tree in regions with warm, subtropical climates. Successful cultivation involves providing partial shade to protect the foliage from intense direct sunlight. Regular watering is essential to maintain the moist soil conditions the species prefers.
Farmers often propagate this plant through seeds or stem cuttings to ensure a steady supply for medicinal use.
What parts of this plant are used medicinally?
This plant uses its stems, leaves, and roots for various medicinal purposes. The wood from the stems is primarily harvested to produce a bitter liquid used to treat fever and digestive issues. Leaves are often prepared as infusions to help manage inflammation and feverish conditions. Additionally, the roots are utilized in traditional practices to address specific ailments like malaria. These different components work together to provide a wide range of therapeutic benefits.
According to a study published by "Chemical & pharmaceuctical bulletin", the stems of Quassia indica are used as an Indonesian medicinal plant. Various quassinoids including four new ones named samaderines X (1), Y (2), Z (3), and indaquassin X (5), along with the C19 quassinoid glycoside 2-O-glucosylsamaderine C (10), were isolated from these stems. Five known quassinoids, samaderines B (7), C (8), and E (4), indaquassin C (6), and simarinolide (9), were also identified. Samaderines X (1), Z (3), E (4), and B (7) showed growth-inhibitory activity against the malaria parasite Plasmodium falciparum. Additionally, compounds 1-8 exhibited in vitro cytotoxicity against KB cells with an IC50 of 0.04-100 micrograms/ml. Samaderines X (1), B (7), C (8), and indaquassin X (5) also showed inhibitory activity in the in vitro endothelial cell-neutrophil leukocyte adhesion assay.
