The essential oil of Buchu leaves is a particularly rich source of bifunctional compounds of the /7-menthane series. Among more than 120 constituents identified, 31 compounds were found to be oxygen-and sulfur-containing derivatives of (H-)-menthone (95) and ( —)-isomen-thone (96), including (83) to (91) 283). In addition to the known... 

Low, aromatic shrubs, usually less than 2 m high with opposite and/or alternate leaves that are finely toothed at the margin and bear oil glands beneath and at the base of the teeth native to South Africa. Parts used are the dried leaves, from which an essential oil is obtained by steam distillation. There are two types of buchu leaves. Round or short buchu is from A. betulina, and long buchu is from A. crenulata-, they differ in the relative compositions of their volatile oils. Major supplies of the leaves (from both wild and cultivated plants) come from the Cape Province of South Afiica, which also produces some of the world s supply of the oil the rest of the oil is distilled in Europe and the United States. Buchu is currently a threatened species. 

Buchu leaves are reported to have urinary antiseptic, diuretic, and carminative properties. The essential oils of Agathosma betulina and A. crenulata leaves have shown spasmolytic activity on the smooth muscle of isolated guinea pig ileum. ...

Buchu leaf oils are obtained by steam distillation of Barosma betulina (Bergius) Bartl. and Wendl. and B. crenulata (L.) Hook. (Rutaceae) leaves. The oils are dark yellow to brown liquids with a characteristic minty-fruity odor, reminiscent of blackcurrant.

Mercapto-p-menthan-3-one has been identified as a constituent of Buchu leaf oil [6] and is a very useful substance in black currant and tropical flavours. The reaction of pulegone with hydrogen sulfide in an alkaline medium results in 8-mercapto-p-menthan-3-one formation (Scheme 13.6).

Owing to their characteristic minty-fruity notes, reminiscent of blackcurrants, buchu leaf oils are well appreciated in the composition of flavourings and fragrances. 8-Mercapto-p-menthan-3-one and its thiolacetate have been described by Sundt et al. [98] and simultaneously by Lamparsky et al. ]99]as impact flavouring compounds of the flavour of cassis. They have so far not been identified in blackcurrant. All four stereoisomers of 8-mercapto-p-menthan-3-one exhibit distinct and characteristic sensory impressions ]100]. 

The (IR)-diastereomers emit a more intensive odour than the (IS)-configured compounds, but only the later diastereomers have been recognized to be peculiar to buchu leaf oil and reminiscent of blackcurrant. An enantio-MDGC method was developed.

Red currant flavor The flavor of red currants is principally due to ( )-2- hexenal, ( )-2- hexen-l-ol, and hexanal (see alkanals). In black currants the im-pact compound 4-methoxy-2-methyl-2-butanethiol (C6H14OS, Mr 134.24, CAS [94087-83-9]) is responsible for the typical feline note. Terpene compounds such as 1,8- cineole, linalool, a-terpineol (see p-menthenols), citronellol and /S- damascenone, fruit esters (e.g., ethyl butanoate), the butter note of 2,3-butanedione, 4-methoxyacetophenone (CgHmOj, Mr 150.18, CAS [100-06-1]) and 2-isopropyl-3-methoxy-pyrazine (see pyrazines) complete the aroma. In the aroma industry buchu leaf oil is used to generate the black currant note.
