The Carotenoids of Algae: Pigments from some Cryptomonads, a Heterokont and some Rhodophyceae

Abstract

SUMMARYThe carotenoids of two Cryptophytes, one heterokont and five Rhodophytes have been examined. The main pigments present are, in Cryptomonas sp., or-carotene and diatoxanthin ; in Hemiselmis virescens, a-carotene, and diatoxanthin ; in Vischeria sp., p-carotene and three unidentified xanthophylls ; in Antithamnion plumula and Nemalion multijidum, B-carotene, lutein and neoxanthin ; in Erythrotrichia carnea, Rhodosorus marinus and Polysiphonia fastigiata, p-carotene, zeaxanthin and lu tein .

The pigments of some marine phytoplankton species

“…It is possible that the minor xanthophyll observed in Hemiselmis virescens Droop by Allen et al (1964) corresponds to one of the two minor xanthophylls listed as 3 and 4 in Table 1; the spectral data do not correspond sufficiently for an unequivocal assignment to be made.

“…(2) This compound was designated diatoxanthin by Allen et al (1964) and 'probably zeaxanthin' by Haxo & Fork (1959). See text.…”

“…This interesting new pigment has the same R P value as fucoxanthin on silica gel G; however, its R P value (0-4) on glucose is less than that of fucoxanthin (0-5). ; Table 3) have been found to contain /?-carotene as their major carotenoid together with four unidentified xanthophylls (Strain, 1958;Allen et al 1964). i).…”

Quantitative variations of individual carotenoids in relationship with the leaflet development of six species of the genus Ceratozamia (Cycads)

“…However, in the case of Cryptophyta algae an infrequent preponderance of a-carotene has been observed (Allen et al, 1964), while in Pheophyta neither a-carotene nor lutein have been detected.…”

“…Recent workers (STRAIN 1958, CHAVMAN 1966 have shown that the only carotenoids found in the Rhodophyta are a-and fl-carotene, lutein and zeaxanthin, although earlier workers had reported finding taraxanthin (HEILBRON 1942, t-[EILBRON, PAR~Y & PHIPERS 1935 and neoxanthin (ALLEN et al 1964) in some species. ALLEN et al (1964, p. 268) state that "the main qualitative differences observed are the presence or absence of a-carotene and the presence or absence of zeaxanthin".…”
