Botany
Malakabuyau is a tree reaching a height of 10 meters, smooth except for the younger branchlets and inflorescences. Trunk is usually spiny. Small spines are usually present on the branches. Leaves are 3-foliate, oblong-ovate to elliptic, entire or somewhat crenate; the terminal one is 6 to 10 centimeters long and the lateral ones are smaller. Flowers are white, fragrant, and about 1.5 centimeters long. Fruit is green or yellow, rough on the outside, oblong, about 10 centimeters long, and 10-celled. Seeds are numerous and surrounded by a fibrous coating.

Distribution
- In thickets and secondary forests at low and medium altitudes from Isabela to Quezon Provinces of Luzon.

Constituents
- Study isolated eleven acridone alkaloids. Three were characterized as: 1,3,5-trihydroxy-4-methoxy-10-methyl-2,8-bis(3-methylbut-2-enyl)acridin- 9(10H)-one (1), 2,3-dihydro-4,9-dihydroxy-2-(2-hydroxypropan-2-yl)-11-methoxy-10-met hylfuro[3,2-b] acridin-5(10H)-one (2) and 3,4-dihydro-3,5,8-trihydroxy-6-methoxy-2,2,7-trimethyl-2H-pyrano[2,3-a] acridin-12(7H)-one (3). (See study below) (3).
- Study of stem bark yielded a new prenylated acridone alkaloid, Study isolated a new prenylated acridone alkaloid, 1,3,5-trihydroxy-2,8-bis(3-methylbut-2-enyl)-10-methyl-9-acridone (1), along with three known alkaloids, 5-hydroxynoracronycine (2), 1,3,5-trihydroxy-4-methoxy-2-(3-methylbut-2-enyl)-10-methyl-9-acridone (3), and 1,3,5-trihydroxy-4-methoxy-10-methylacridone (4).

- Leaves and bark used for cough.


Studies
Anti-Tuberculosis / Essential Oil:
Study assessed the in vitro antitubercular activity of essential oils of 11 medicinal plants grown in Columbia. The major components were carvacrol, thymol, p-cymene, 1,8-cineole, limonene and beta-pinene. INH and rifampin were used for control treatments. Essential oil from S. glutinosa showed a minimal inhibitory activity of 100 ±36 mcg/ml(-1). Results showed the essential oils from Achyrocline alata and Swinglea glutinosa were the most active and suggests A alata and S glutinosa and their identified components are potential candidates as phytotherapeutic antitubercular agents. (1)
Alkaloids / Cytotoxicity / Anti-Plasmodial / Stem Bark: Study isolated a new prenylated acridone alkaloid from the stem-bark of S glutinosa, along with three known acridone aklaloids. The isolated alkaloids were assessed for anti-plasmodial activity and for cytotoxicity using HeLa cells. (2)
Antiparasitic / Anti-Plasmodial: Study evaluated the in vitro anti-plasmodial activity of 11 acridone alkaloids isolated from S. glutinosa. Nine had varying range of activity against P. falcifarum, a smaller number against T brucei rhodesiense and Leishmania donovani. (3)
Cytotoxicity / Stems and Fruits: A methanol extract from stems and fruits yielded 11 known acridone alkaloids and three N-phenylethyl-benzamide derivatives. The compounds were examined against three cancer cell lines. The acridones exhibited weak cytotoxicity but the amides showed moderate nonselective activity. (6)
Bioactive Acridone Alkaloids / Stem Bark: Study isolated a new prenylated acridone alkaloids, 1,3,5-trihydroxy-2,8-bis(3-methylbut-2-enyl)-10-methyl-9-acridone (1), from the stem bark of S. glutinosa along with three known alkaloids. The isolated alkaloids were assessed for in vitro activity against chloroquine- sensitive Plasmodium falcifarum strains and cytotoxicity using HeLa cells. (8)
Natural Repellent / Anti-QS / Essential Oil: Essential oils from six plants cultivated in Colombia, including Swinglea glutinosa, were evaluated for repellent activity and quorum sensing (QS) inhibition. Results suggest the EOs are sustainable, promising new sources of natural repellents and could be important as anti-quorum sensing molecules. (10)
Acridone Alkaloids / Cathepsin V Inhibitor: Cathepsin V is a lysosomal cysteine peptidase highly expressed in thymus, testis, and corneal epithelium. Study isolated 11 acridone alkaloids with eight identified as potent and reversible inhibitors of cathepsin V (IC50 1.2-3.9 µM). The most potent inhibitor (7) had a K(i) value of 200 nM. (11)
Antioxidant / Fatty Acid Composition / Leaves and Fruits: Study evaluated the antioxidant capacity of methanolic extracts and fatty acid composition of leaves and fruits of S. glutinosa. Results showed an IC50 of 28.2 g/mL for the leaf extract, and 10 µg µg/mL for the fruit extract by DPPH method. The fruit extract showed highest anti-radical effect while the leaf extract showed highest effect against lipid peroxidation. On GC analysis, the major fatty acid was linoleic and oleic acids, 0.5% for both. (12)
Acari Control / Combination with Avermectins / Leaves: Invention reports on the application of a natural material derived from Swinglea glutinosa leaves in combination with avermectins which increases the effect of avermectins over mites. Results suggest an all natural material with potential to replace avermectin combinations with synthetic pyrethroids. (13)
