Plant terpenoids are used for their aromatic qualities and play a role in traditional herbal remedies. Terpenoids contribute to the scent of eucalyptus , the flavors of cinnamon , cloves , and ginger , the yellow color in sunflowers , and the red color in tomatoes . [3] Well-known terpenoids include citral , menthol , camphor , salvinorin A in the plant Salvia divinorum , the cannabinoids found in cannabis , ginkgolide and bilobalide found in Ginkgo biloba , and the curcuminoids found in turmeric and mustard seed .

While terpenes and terpenoids occur widely, their extraction from natural sources is often problematic. Consequently, they are produced by chemical synthesis, usually from petrochemicals . In one route, acetone and acetylene are condensed to give 2-Methylbut-3-yn-2-ol , which is extended with acetoacetic ester to give geranyl alcohol. Others are prepared from those terpenes and terpenoids that are readily isolated in quantity, say from the paper and tall oil industries. For example, α-pinene , which is really obtainable from natural sources, is converted to citronellal and camphor . Citronellal is also converted to rose oxide and menthol . [1]
