[Chemical constituents of seeds of Camellia sinensis var. assamica].

Five compounds were isolated from the acid-hydrolytic products of n-butanol extract and ethanol extract of the seeds of Camellia sinensis var. assamica. Their structures were elucidated by chemical and spectroscopic analyses as octacosane, three new acyl-sapogenins: 22-O-angeloyl theasapogenol B, 22-O-angeloyl theasapogenol E and 22-O-angeloyl theasapogenol A, and naringenin respectively.
