Noni fruit is a fleshy and densely clustered globose syncarp. It is globose-ovoid, cone-like, yellowish white and somewhat gelatinous when ripe. Noni fruit contains seeds which have alkaloids, but not there are no alkaloids in the fruit itself. The fruit contains polysaccarides, scopoletin, vitamins and minerals. 
It takes about one year for fruit to develop on new trees. Once established, noni trees bear fruit year-round.
Some of the compounds identified in noni fruit include: acetic acid, asperuloside, benzoic acid, benzyl alcohol, butanoic acid (n-butyric acid), I-butanol, n-butyric acid, calcium, carotene, decanoic acid, 6-dodeceno-y -lactone 8,11,14-eicosatrienoic acid, elaidic acid, ethyl decanoate, ethyl hexanoate, ethyl octanoate, ethyl palmitate, (ethylthiomethyl) benzene, eugenol, glucose, heptanoic acid, 2-heptanone, hexadecane, hexanamide, hexanedioic acid, hexanoic acid, 1-hexanol, hexyl hexanoate, 3-hydroxy-2-butanone, iron, isobutyric acid, isocaproic acid, isovaleric acid, lauric acid, limonene, linoleic acid, magnesium, 2-methylbutanoic acid, 2-methyl-2-butenyl decanoate, 2-methyl-2-butenyl hexanoate, 3-methyl-2-buten-l-ol, 3-methyl-3-buten-l-ol, methyl decanoate, methyl elaidate, methyl hexanoate, methyl 3-methylthio-propanoate, methyl octanoate, methyl oleate, methyl palmitate, 2-methylpropanoic acid, 3-methylthiopropanoic acid, myristic acid, nonanoic acid, octanoic acid, oleic acid, palmitic acid, paraffin, potassium, scopoletin, sodium, terpenoids , 2,5-undecadien-l-ol, undecanoic acid, n-valeric acid, vitamin C, and vomifoliol.
