“…The average oil percentage in “dried” P. cablin leaves as reported in 72 references was calculated as 2.6% (ranges: 0.54 – 5.2%) . However in view of the discussion below, this figure is not precise as it is dependent on the exact plant material used (cultivar, age, soil and growth conditions), percentage of stems as well as foreign materials (soil, other plant species like weeds), drying and/or fermentation, storage, final percentage of water and the distillation technique, conditions and duration.…”

The leaves of Pogostemon cablin (Blanco) Benth. (Lamiaceae) are the source of patchouli essential oil, which is -with an annual production of about 1300 tonnes -an important and unique commodity in the fragrance industry. All the literature pertaining to patchouli was critically reviewed with an emphasis on the qualitative and quantitative chemical analysis of the oil but also harvesting, fermentation, drying, distillation, used analytical techniques, sensory aspects including molecules responsible for the odour, adulteration and toxicological aspects, i.e., skin sensitisation, are discussed. In total 72 constituents have been convincingly identified in the oil and another 58 tentatively. The main constituent is the sesquiterpene patchoulol. For this review over 600 papers were consulted and in the supplementary information all patchouli-related references not relevant enough to be cited in the paper itself are listed. 6 It has been stated that "this oil is one of the most important materials available to the perfumer." 7 Approximately 90% of today's global production of 1200-1300 metric tonnes per annum is realised in Indonesia. --------------------------------------------------------------------------------------------------------------------------------This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Patchouli, Pogostemon cablin Benth., is an important source of essential oil. On the basis of botanical observations and gas‐chromatographic patterns of oils obtained, the major characteristics of three cultivars were compared. From cultivar I, an oil close to that commercially available was produced with a yield of 1.6% (wt/wt). From cultivar II, a lower yield of an oil having an additional component was obtained. From cultivar III, a relatively high amount of oil was recovered from each plant owing to the bigger canopy it forms. The quality of the oil, however, was judged to be markedly different from that of others. Each cultivar could be identified by its characteristic leaf morphology and trichome density.

SummaryThis work describes a potexvirus obtained from patchouli, Pogostemon clabin, collected in São Paulo, Brazil in 1992. The plants showed mosaic and were infected by a potyvirus and a potexvirus. The potexvirus had a host range limited to Amaranthaceae, Solanaceae and Labiatae and was named Patchouli virus X (PatVX). PatVX was not transmitted by scissors pruning, in tobacco seeds or by Myzus nicotinae. The virus was purified and a specific antiserum with a titre great than 1:512 000 in dot‐ELISA was produced. The virus was serologically related to Papaya mosaic virus, Potato virus X, Viola mottle virus, White clover mosaic virus and Lily virus X. It had a coat protein of 21 071 ± 1 010 Mr. as determined by SDS‐PAGE. Immunolabelling tests demonstrated that fibrillar masses in the cytoplasm contain the coat protein. The presence of a dsRNA was detected in PatVX infected plants.
