From the seeds of Impatiens balsamina has been isolated five novel baccharane glycosides, hosenkosides A-E.The structure of all isolates were secured by the use of 2D NMR techniques (1H-1H COSY, HMQC, HMBC, ROESY, TOCSY), CD spectroscopy and chemical derivatization.

From the seeds of Impatiens balsamina we have isolated six novel baccharane glycosides, hosenkosides F-K. The structures of all isolates were determined by the use of two dimensional (2D) NMR techniques (1H-1H correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear multiple-bond correlation (HMBC), rotating frame Overhauser enhancement spectroscopy (ROESY), total correlation spectroscopy (TOCSY)) and chemical derivatization. Hosenkosides F, H and I are hosenkol B 3-O-sambubiosido-26-O-glucoside, 3-O-sambubioside and 3,26-O-diglucoside, respectively. Hosenkoside G is hosenkol C 3-O-sambubiosido-28-O-glucoside. Hosenkosides J and K are hosenkol A 3-O-sophoroside and 3-O-sophorosido-26- O-glucosyl-28-O-glucoside, respectively.
