Hypoglycemic activity of several kinds of Japanese tea was examined and bancha was found to have potential hypoglycemic activity in streptozotocin-induced hyperglycemic and normal rats. One of the active principles was purified by chromatograph on Toyopearl HW-50F and diethylaminoethyl-cellulose and determined to be heteropolysaccharide (T-b) consisting of arabinose, D-ribose and D-glucose (5.1 : 4.7 : 1.7), which gave a molecular weight of approximately 4×104.

A new glycoside (I), C_<24>H_<26>O_<18>・11/2H_2O, mp 274-275°, was isolated from Chrysosplenium grayanum MAXIM. (Japanese name"Nekonomeso"), and a glycoside (II), C_<24>H_<26>O_<12>・2H_2O, mp 175-176°, from C. flagelliferum FR. SCHM. (Japanese name"Tsurunekonomeso"). I was determined as oxyayanin-A (5,2', 5'-trihydroxy-3,7,4'-trimethoxyflavone)-2'-glucoside, and was named chrysosplenoside-A , and II as pendulin (5,4'-dihydroxy-3,6,7-trimethoxyflavone-4'-glucoside).

A new glycoside (I), C24H26O18·11/2H2O, mp 274-275°, was isolated from Chrysosplenium grayanum MAXIM. (Japanese name"Nekonomeso"), and a glycoside (II), C24H26O12·2H2O, mp 175-176°, from C. flagelliferum FR. SCHM. (Japanese name"Tsurunekonomeso"). I was determined as oxyayanin-A (5, 2', 5'-trihydroxy-3, 7, 4'-trimethoxyflavone)-2'-glucoside, and was named chrysosplenoside-A, and II as pendulin (5, 4'-dihydroxy-3, 6, 7-trimethoxyflavone-4'-glucoside).
