“…These estimates of the proportions of the isomers were in good agreement with those obtained from countercurrent distribution (409) and reversed-phase chromatography (356,358,359). 0 HC-OH X Thus, when beer is exposed to sunlight it develops an unpleasant "sunstruck" flavor due to the formation of isopentenylthiol (Cl).…”

“…Many techniques have been used in order to resolve the natural mixtures of hop resins, including chromatography on silica gel (336), perlón (156), paper (335), ion-exchange resins (71,194,342), and papers modified with ion-exchange resins (322). Countercurrent distribution (303,304,390), steady-state distribution (9,12), partition chromatography (387,388), and reversed-phase chromatography, both in columns (30,355,356,360,363) and on paper (408), have been fruitfully employed as have paper electrophoresis (256) and thin film chromatography (160,161,184,238,239,240).…”

“…In addition to countercurrent distribution and partition chromatography mentioned above, the mixture of analogs present in the -acid fraction has been resolved by reversed-phase column chromatography (30,355,356,360,361) and on paper (408), by steadystate distribution (9,12), by chromatography on polyamides (Perlón) (156), and by ion-exchange chromatography using frontal analysis (342), but not by ordinary elution (194).…”

“…Sutherland and Waters (682) studied the structure of humulene; McPhail, Reed, and Sim (390) established its stereochemistry; and Hartsuk and Paul (233) used x-ray analysis to clarify its molecular structure. Stevens (667) investigated the oil from an abnormal hop variety, and found it to consist principally of myrcene and /3-selinene; and Spetzig (660) described an apparatus for partition chromatography and its application to the separation of the bitter substances of hops.…”

From Abies sibirica oil Porsch and Farnow (552) isolated tricyclene and established its structure. Sesquiterpenes from the same plant were identified by Chirkova and Pentegova (93).The oil of Achryocline satureioides was investigated by Ricciardi, Cassano, and Burgos (573) and some of its constituents were identified.The composition of agarwood oil was examined by Jain, Maheshwari, and Bhattacharyya (294), and Maheshwari et al. (391, 392) isolated and characterized several sesquiterpenic furans from the oil.Benzyl acetate and benzoate were found in the oil from Albizzia lebbeck flowers by Jain and Mishra (293).The properties of the oil of Alpinia galanga were ascertained by Trabaud (716) who identified several of its main constituents. Nigam and Radhakrishnan (483,484) reported quite different properties for an oil from the same

“…Auxins (1491, 1658) and gibberellins (896,967,1406,1518) have been separated by paper as well as TLC. Other plant acids for which new chromatographic procedures have been described include ellagic acid (228), the bitter substances in hops (640,1475), resin acids (79, 211, 349), and humic acids (1258).…”
