“…clearly exhibited 29 carbon signals (6´CH 3 , 8´CH 2 , 8Ć H, 5´C, 2´CO). Based on the HR EIMS, the molecular formula was established as C8 H 15 (m/z 111.1185), indicating one degree of unsaturation. 458.3610) indicating seven degrees of unsaturation, ascribed to two carbonyl groups, four steroid rings, and one double bond.…”

Calorimetric Studies on the Phenolic Glycoside D(–)-Salicin

“…From the last two values the standard entropy of fusion is calculated as ${\rm \Delta }_{{\rm cr}}^{\rm l} S_{\rm m} ^\circ$ = (116.9 ± 0.4) J mol −1 K −1 . The temperature of fusion indicated in the literature for D ()‐salicin spans in the range T = 464–477 K 31–37…”

Phenolic Glycosides from the Twigs of Salix glandulosa

“…2−6 Salix glandulosa Seemen (= S. chaenomeloides Kimura, Salicaceae), also called "Korean King Willow", is distributed in Korea, Japan, and mainland China, reaching up to 20 m in height. Although several salicin derivatives and flavonoids were isolated from this plant, 7 it was decided that an additional investigation was merited.…”
