¹³C Solid-state NMR experiments were performed to investigate the structure of beeswax in the native state (crude beeswax) for the first time. From quantitative direct polarization ¹³C MAS NMR spectrum, it was found that the fraction of internal-chain methylene (int-(CH₂)) component compared to other components of crude beeswax was over 95%. The line shape of the int-(CH₂) carbon resonance region was comprehensively analyzed in terms of NMR chemical shift. The ¹³C broad peak component covering from 31 to 35ppm corresponds to int-(CH₂) carbons with trans conformation in crystalline domains, whereas the sharp signal at 30.3 ppm corresponds to gauche conformation in the non-crystalline domain. From peak deconvolution of the aliphatic region, it was found that over 85% of the int-(CH₂) has a crystal structure and several kinds of molecular packing for int-(CH₂), at least three, exist in the crystalline domain.
