Serotonin derivatives found in safflower seeds[edit]
N-Feruloylserotonin and N-(p-coumaroyl)serotonin are natural products that can be found in the extract of safflower seeds (Carthamus tinctorius).[2] These natural products have been isolated and studied to investigate their antioxidant effects.[3] These polyphenols have been utilized in traditional Chinese medicine and other eastern medicine practices to have strong antioxidant effects, chemotherapeutic effects, and atherosclerosis attenuation.[1][4] It has been found that N-(p-coumaroyl) and N- feruloyl serotonin can suppress the expression of matrix metalloproteinases MMP3/13 and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS), thus attenuating cartilage degradation.[2]
The biosynthetic pathway of N-feruloylserotonin and N-(p-coumaroyl)serotonin has been reported.[5] In plants, the enzyme anthranilate synthase (AS) is composed of two subunits that modulate the production or suppression of tryptophan from chorismate.[6] Tryptophan is then decarboxylated by tryptophan decarboxylase (TDC) into tryptamine.[5] Tryptamine 5-hydroxylase (T5H) then hydroxylates tryptamine into serotonin.[7][8]Serotonin, the precursor to N-(p-coumaroyl) and N-feruloylserotonin, is found in the seeds of the safflower plant.[9][10][11]Hydroxycinnamic acids are then transferred to serotonin from hydroxycinnamoyl-CoA esters by hydroxycinnamoyl-CoA: serotonin N-(hydroxycinnamoyl)transferase (SHT).[6]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
