"Loquats are unusual among fruit trees in that the flowers appear in the autumn or early winter, and the fruits are ripe at any time from early spring to early summer. The flowers are 2 cm (1 in) in diameter, white, with five petals, and produced in stiff panicles of three to ten flowers. The flowers have a sweet, heady aroma that can be smelled from a distance... The fruits are the sweetest when soft and orange. The flavour is a mixture of peach, citrus and mild mango." \\ | "Loquats are unusual among fruit trees in that the flowers appear in the autumn or early winter, and the fruits are ripe at any time from early spring to early summer.

2-Nitroethyl benzene (32.5%) was identified as a major component of the flower scent of the Japanese loquat Eriobotrya japonica, together with 4-methoxybenzaldehyde (27.1%) and methyl 4-methoxybenzoate (24.5%). Minor components were e.g. benzaldehyde (1.6%), phenylethanol (3.3%), 2-phenylacetontiril (0.9%), 2-phenylacetoaldoxime (0.8%), and methyl cinnamate (7.1%). \\ | 2-Nitroethyl benzene (1-nitro-2-phenylethane, 32.5%) was identified as a major component of the //flower scent// of the Japanese loquat Eriobotrya japonica, together with 4-methoxybenzaldehyde (anisaldehyde, 27.1%) and methyl 4-methoxybenzoate (methyl anisate, 24.5%).
