The thymol concentration decreased slightly but not significantly in all four varieties the thymol in M2 and M4 was very high compared with M1 and M3. However, it increased only slightly in M2 and M4. At the first harvest, the essential oil yield of the four varieties showed that M1H1 had a yield of 1.15%, higher than M2H1, M3H1, and M4H1 with 0.91, 0.76, and 1.03%, respectively. Essential oils were obtained by hydrodistillation with continuous extraction with dichloromethane using a Likens–Nickerson apparatus and analyzed by gas chromatographic techniques. The study’s objective was to compare the four varieties for essential oil yield and their composition at three harvest times, 135, 155, and 170 days after planting (DAP). The plots were arranged in a randomized complete block with three replications. Thirty-day-old greenhouse-grown plants of the four varieties were transplanted on raised beds in the field at the Alabama A & M University Research Station in North Alabama. Towards this end, four field-grown varieties with three harvesting times (M1H1, M1H2, M1H3 M2H1, M2H2, M2H3 M3H1, M3H2, M3H3, M4H1, M4H2, M4H3) were evaluated for relative differences in essential oil yield and composition. virginianum that can be adapted and easily grown for production in North Alabama. There is, however, a need for varieties of P. North Alabama’s climate is conducive to growing mint for essential oils used in culinary, confectionery, and medicinal purposes. Virginia mountain mint ( Pycnanthemum virginianum) is a peppermint-flavored aromatic herb of the Lamiaceae and is mainly used for culinary, medicinal, aromatic, and ornamental purposes.
