Description
Qianting Ma and coauthors characterize a wild tea plant with naturally low caffeine from Guangxi in a 2026 study. The upright tree type plant bears narrow leaves and five petal flowers. Fresh leaves were compared chemically against three standard cultivars.
Theobromine, a gentler related alkaloid, topped the alkaloid list instead of caffeine. Its caffeine and total catechins ran far below the standard cultivars. Fifteen distinctive non volatile compounds and twenty two key aroma compounds were catalogued. Floral, fruity, and green notes dominate its scent profile. Tea breeders gain a natural low caffeine resource for new product lines.
