Do mandarins contain furanocoumarins?
Other varieties such as mandarins, small mandarin hybrids, sweet oranges, some limes, some lemons, Ichang papeda and Mountain display low amounts of coumarins and furanocoumarins in both their peel and pulp.
Does grapefruit peel contain furanocoumarins?
Similarly, coumarins and furanocoumarins can be extracted by methanol/water (80:20) from the peel and pulp of 61 Citrus species with results showing the major furanocoumarins present in grapefruit peel and pulp to be 6′,7′-dihydroxybergamottin, epoxybergamottin, and bergamottin [2].
Which fruits contain furanocoumarins?
Pomelos (a hybrid between an orange and an Asian fruit called Citrus maxima) also contain furanocoumarins, as do Seville oranges (used in marmalades) and limes.
Does lemon contain furanocoumarins?
ABSTRACT: Coumarins and furanocoumarins are secondary metabolites commonly found in citrus plants. 1 Citrus production can be divided into four primary groups: sweet oranges, mandarins (including clementine and tangerine), grapefruit (including pummelo), and lemons/limes.
Do limes contain furanocoumarins?
Limes contain numerous furanocoumarin compounds, including limettin (also called citropten), bergapten, isopimpinellin, xanthotoxin (also called methoxsalen), and psoralen. Bergapten appears to be the primary furanocoumarin compound responsible for lime-induced phytophotodermatitis.
What do furanocoumarins do?
Furanocoumarins may be produced by plants as a defense mechanism against predators such as insects and mammals. It is also likely that furanocoumarins are related to a plant’s natural defense against fungal attack.
Does bergamot have furanocoumarins?
Bergamot (Citrus bergamia Risso) fruit and juice (BJ) are a source of bitter taste compounds containing mainly the flavanones neohesperidin, naringin, neoeriocitrin and lesser amounts of flavones and furanocoumarins.
Which foods have furanocoumarins?
Furanocoumarins are found in the sap of plants such as Ammi majus, parsnip, and giant hogweed. At least 36 species of the genus Heracleum in the family Apiaceae are known to contain one or more furanocoumarin compounds.
What is Furocoumarin free?

Furocoumarin Free – significantly reduced / removed via further & short path molecular evaporation to de-Furocoumarins the oil. Commonly used in insect repellents & for insect bites.
Do limes have furanocoumarins?
Limes contain numerous furanocoumarin compounds, including limettin (also called citropten), bergapten, isopimpinellin, xanthotoxin (also called methoxsalen), and psoralen.
Is lime a lemon?
Are limes unripe lemons? No, limes are not unripe lemons. While both fruits look alike and can be easily confused, they are, in fact, quite different. The shape of both fruits is also a good differentiator.
What plants contain Furocoumarins?
What is a furocoumarin?
Furocoumarins are a class of secondary metabolites found in various plant species world-wide [1, 2]. High furocoumarin contents have been found in the Apiaceae family such as celery, parsnip, and parsley or in the Rutaceae including all citrus fruits [2]. …
How are coumarin and furanocoumarin profiles represented in citrusspecies?
Coumarins are represented in orange; furanocoumarins of the bergapten cluster, in blue; furanocoumarins of the xanthotoxin cluster, in red; and furanocoumarins of the isopimpinellin cluster, in green. Open in a separate window Fig 5 Heatmap displaying the coumarin and furanocoumarin profiles in the pulp of the 61 Citrusspecies investigated.
Should the maximum content of ‘furocoumarin-like substances’ be limited?
The IFRA maximum for furanocoumarins is 15 ppm. It has been proposed that manufacturers of cosmetic products in EC countries be required to limit the maximum content of ‘furocoumarin-like substances’ to 1 ppm ( SCCNFP 2003b ). This limit appears to be an arbitrary figure, and the proposal is based on the assumption that all FCs are photomutagenic.
How much furocoumarin is in grapefruit?
In the westernized populations, the estimated average total intake of dietary furocoumarins is about 1.2-1.5 mg/d with Citrus species, such as grapefruit, being the main sources [16], while high-exposure peak values may reach 14 mg/d [17]. The major furocoumarins of grapefruit are bergaptol, bergamottin, and 6 ,7 -dihydroxy-bergamottin [18].
