The best quality patchouli oil based on Indonesian national standards is a minimum PA content of 31% [9]. Therefore, the ex vitro patchouli oil yield was 4% (v/dw) and the in vitro patchouli oil yield was 2% (v/dw). Scan results from commercial patchouli oil samples, plant origin (ex vitro) and in vitro cultures yielded qualitatively the same spectrum profile.
Spectrum of patchouli oil samples (a) commercial; (b) Ex vitro; (c) In vitro at λ = 200–400 nm with n-hexane eluent by UV-Vis spectrophotometry. Based on the GC profile results of patchouli oil (Figure 2), it was found that patchouli oil from commercial patchouli plants, ex vitro and in vitro, contains several components, including patchouli alcohol (PA), which is the main component of patchouli oil. . Chromatogram of patchouli oil samples (a) commercial; (b) Ex vitro; (c) In vitro using gas chromatography with an HP-INNOWax column.
Retention Time and PA Level of Patchouli Oil Samples Using Gas Chromatography Analysis Sample Replication Retention Time. The hydrodistillation of patchouli leaves ex vitro yielded higher patchouli oil [4% (v/dw)] than patchouli leaves in vitro [2% (v/dw)]. Based on Table 4, PA levels of ex vitro oil were significantly different from commercial patchouli oil as well as in vitro oil to commercial patchouli oil.
Therefore, the PA levels of patchouli oil obtained in vitro were slightly higher than ex vitro and were still below commercial patchouli oil.
