NMR and ESIMS data for bisabolane-type sesquiterpenoids

Abstract The data presented here are related to the research paper entitled “Norbisabolane and bisabolane sesquiterpenoids from the seeds of Angelica keiskei” [1]. In this data article, we provide 1D and 2D nuclear magnetic resonance (NMR) spectroscopy and electrospray ionization mass spectrometry (ESIMS) data of three undescribed norbisabolane- and bisabolene-type sesquiterpenoids, ashitabaol B-D isolated from the seeds of Angelica keiskei.
