Langsat Seed Limonoids: An Antimalarial Lab Study
Longkong / Langsat · ลองกอง · Lansium parasiticum
Longkong / Langsat — ลองกอง (long-kong) — Lansium parasiticum.
Langsat — long-kong. You spit out its bitter seeds, but their limonoid compounds showed antimalarial activity in early test-tube studies. To eat langsat, peel the tan skin and enjoy the sweet, translucent flesh, spitting out the bitter seeds. A 2022 review reports antioxidant compounds in the fruit, which also brings fiber and copper. Fiber keeps digestion regular, helps you feel full, and slows how fast sugar is absorbed. Copper helps your body put iron to work, supports normal energy metabolism, and builds healthy connective tissue and nerves. Yam Langsat tosses the peeled fruit segments with crispy fried fish, shallots, and a fiery chili-lime dressing. Langsat Loi Kaew steeps the deseeded fruit in a fragrant jasmine syrup, served ice-cold over crushed ice. Longkong is just a thin-skinned, near-seedless langsat, the same species bred sweeter with almost no seed to spit out. Follow Longevity Biome for a new Thai plant every day.
