AbstractDer aus der roten Passionsfrucht isolierte Aromastoff (III) kann entweder durch Wittig‐Reaktion aus Verbindung (II) oder durch Thermolyse der leicht darstellbaren Verbindung (VI) erhalten werden.

Megastigma‐5,8‐dien‐4‐one, an aroma constituent of the yellow passion fruit and Virginia tobaccoPreparative gas chromatography allowed isolation of megastigma‐5, 8 (E)‐dien‐4‐one (3) from small subfractions of both yellow passion fruit and Virginia tobacco condensates. Along with 3, the Z‐isomer 4 occurs in the aroma of the yellow passion fruit. Both these novel flavor compounds were synthesized by a two‐step, non‐biomimetic route starting from 2, 6, 6‐trimethylcyclohex‐2‐en‐1‐one. The E‐isomer 3 was also formed by acid‐catalyzed dehydration/rearrangements of ionol‐ and damascol monoepoxides 5, 6, 7, 8 and hydroxy‐ionols and ‐damascol 9, 10 and 11. Such a biomimetic conversion indirectly supports the assumption that 3 and 4 might originate from the oxidative degradation of carotenoid precursors possibly related to canthaxanthine.

Aroma Constituents of the Purple Passion Fruit. Two New Edulan DerivativesThe isolation of (2R*, 4S*, 4aS*, 8aS*)‐4,4a‐epoxy‐4,4a‐dihydroedulan (1), and (2R*, 3S*, 8aS*)‐3‐hydroxyedulan (2), two new constituents of the purple passion‐fruit (Passiflora edulis SIMS), is reported.Racemic epoxide 1 was synthesized by oxidation of edulan 6 with peracidic acid, and racemate of alcohol 2 was obtained by reduction of ketone 7, one of the chromic acid oxidation‐products of edulan 6.

Ethyl (Z)‐4,7‐Octadienoate and (Z)‐3,5‐Hexadienyl Butyrate, two New Aroma Components of the Purple PassionfruitThe isolation of ethyl (Z)‐4,7‐octadienoate (1) and (Z)‐3,5‐hexadienyl butyrate (2), two new and important aroma constituents of the purple passionfruit (Passiflora edulis SIMS) is reported.Ester 1 was synthesized by two different routes: (1) via a Wittig reaction between the known 4‐oxobutyrate 4 and 3‐butenylidenephosphorane, and (2) by thermolysis of (Z)‐8‐acetoxy‐4‐octenoate 7 which was readily accessible from (Z,Z)‐1,5‐cyclooctadiene.Ester 2 was prepared from the known hex‐3‐yn‐5‐en‐1‐ol (8) by a stereoselective (Z)‐reduction of the triple bond to 9, using Rieke's active metallic zinc, followed by esterification.The organoleptic properties and the taste threshold values of 1 and 2 are given.

Plants have been the basis of many traditional medicines throughout the world for thousands of years and have continued to provide new remedies to mankind. They are one of the richest sources of bioactive compounds. The genus Passiflora comprises about 520 species of dicotyledonous plants in the family Passifloraceae. Passiflora edulis is also known as passion fruit, grenadelle, grenadine, passionflower, purple granadilla, or purple passion fruit. Native to southern Brazil, Paraguay to northern Argentina, P. edulis is a medicinal plant distributed in warm temperatures and tropical regions. In traditional system of medicines this species has a key role in management or treatment of various ailments. Properties traditionally recognized include anxiolytic, antiinflammatory, sedative, antioxidant, antispasmodic, antioxidant, and neuroprotective. This chapter aims to evaluate and comment on the scientific evidence regarding the therapeutic use and basis for future research on P. edulis, and its real potential for the development of the market for herbal medicinal products; to summarize the chemical constituents of therapeutic preparations; to analyze the pharmacological aspects of the plant by examining both preclinical and clinical research, and to assess the toxicity and safety profile.

3-Methylthio-hexanol (3) and a mixture of cis- and trans-2-methyl-4-propyl-1, 3-oxathiane (6a and 6b) have been identified in a flavor concentrate of the yellow passion fruit of Hawaiian origin. Syntheses of these new flavor constituents are described.
