 Title    Screening of Aromatic Secondary Lichen Substances by High Performance Liquid Chromatography  
 Abstract    A simple HPLC m ethod is described which allows screening and accurate quantification o f aro­ matic secondary lichen substances. U sing a linear water-methanol gradient on a reversed-phase column packing (LiChrosorb RP-8) 13 aromatic lichen products were resolved within 55 min. With 8 arbitrarily selected lichens the application o f the described m ethod is demonstrated.

 Title    P henolics from Larix N eedles. XV. H igh-Perform ance Liquid Chromatography  
 Abstract    From needles of Larix gmelinii sixteen flavonoids were isolated and identified. The main flavonoids had been analyzed before, eight minor ones were identified as quercetin-3-glucoside, isorhamnetin-3-glucoside and -3-ara-binoside, a somewhat lipophilic kaempferol-3-glucoside derivative, apigenin-7-glucoside, laricitrin-3-rutinoside and laricitrin-and syringetin-3-(/?-coumarylglucoside).

 Title    The Coloration of Gladiolus I. Survey of Anthocyanins in Petals of Gladiolus  
 Abstract    The six common anthocyanidins found in Gladiolus petals occur in four types o f glycosilation: 3-glucoside, 3-rhamnoglucoside, 3,5-diglucoside, and 3-rhamnoglucoside-5-glucoside. The six monoglucosides appear in minute quantities, whereas any of the other 18 anthocyanins can serve as the m ajor contributor to the coloration of Gladiolus petals. In high performance liquid chrom atographic analyses of petal pigm ent composition o f nine cultivars, it was found that the anthocyanins are grouped on the basis of the aglycon substitution. Thus, pelargonidin appears by itself (group I), cyanidin and peonidin constitute group II, and delphinidin, petunidin, and malvidin group III.

 Title    Determination of Hyoscyamine and Scopolamine in Datura innoxia Plants by High Performance Liquid Chromatography  
 Abstract    For the determination of the hyoscyamine-scopolamine content in small quantities of fresh plant tissue an HPLC assay was developed; with a sensitivity of about 20 ng alkaloid per run. Analysis of the different organs of Datura innoxia plants are in accord with the concept that hyoscyamine is synthesized in the roots, whereas transformation to scopolamine starts in these organs and proceeds in the aerial parts of the plant.

 Title    Aloe Plants Accumulate Anthrone-Type Anthranoids in Inflorescence and Leaves, and Tetrahydroanthracenes in Roots  
 Abstract    The accumulation and distribution of characteristic secondary products in the different organs of an A loe plant (A. succotrina Lam.) were studied by high perform ance liquid chro­ matography for the first time. In the leaves of the A loe plant, only anthrone-C-glycosyls of the 7-hydroxyaloin type and, for the first time in plant material, the free anthraquinone 7-hydroxyaloeemodin were found. In contrast to previous reports on the distribution of sec­ ondary products in A lo e plants, anthrone-C-glycosyls were also detected in flowers, bracts and the inflorescence axis of the species examined. Aloesaponol I, a tetrahydroanthracene aglycone, was only present in the underground organs and in the stem. The 2-alkylchromone-C-glucosyl aloeresin B showed no specific occurrence as it was found in every type of organ. Based on these results and the findings of recent studies on A loe roots and flowers, a distri­ bution scheme of polyketide types in the A loe plant was established. It suggests a separate and independent anthranoid metabolism for underground A loe organs and stem on the one hand, and for leaves and inflorescence organs on the other hand. In the latter structures anthranoid metabolism seems to be additionally compartmentalized as the anthranoid pro­ files of inflorescence organs and leaves differ in two points relevant to anthranoid biosynthe­ sis: firstly, the occurrence of anthrone aglycones and secondly, the individual content of corre­ sponding anthrone-C-glucosyl diastereomers.

 Title    The Structures of Sinapic Acid Esters and Their Metabolism in Cotyledons of Raphanus sativus  
 Abstract    Five sinapic acid esters were isolated from cotyledons of Raphanus sativus and have been iden­ tified with the aid of electron impact (El)-, field desorption (FD)-mass spectrometry and NMR spectroscopy: 6,3'-disinapoylsucrose, sinapoylcholine (sinapine), 6 -sinapoylglucoraphenine, 1 -si­ napoylglucose, and sinapoylmalate. Three of these derivatives are metabolically related in the se­ quence sinapoylcholine -» • 1 -sinapoylglucose — ► sinapoylmalate.

 Title    Distribution of cis-iraws-ß-Carotene in Pigment-Protein Fractions of Photosystem I and II  
 Abstract    The distribution of isomers of ß-carotene is reported in the CP-47 pigment-protein complex of photosystem II and photosystem I (PS I) from barley. The distribution of carotenoids from light harvester complex II is reported. CP-47 lacks 9,9'-rá-carotene, but contains 9,13'-c/s-carotene; PS I lacks 9,\2>'-cis but contains 9,9'-eis. More 9-eis, 9,13-cw, 9,15-c/s, and epoxide is observed in CP-47 than in PS I.

 Title    Application of Liquid Chromatography to a Study on 4-Coumarate: Coenzyme A Ligase Activity  
 Abstract    This report describes the separation of components from a 4-coumarate: CoA ligase assay by means of liquid chromatography. With the aid o f polyamide column chromatography it is possible to enrich and isolate chromatographically and UV spectroscopically pure /»-coumaroyl-CoA using as a solvent 0.01% N H 4OH in methanol subsequent to water and methanol alone. High performance liquid chromatography on octadecylsilane-bonded silica stationary phase allows a discontinuous determination o f ligase activity. All components — ATP, Coenzyme A, p-coumaric acid, and the products AMP and p-coumaroyl-CoA — can be separated and accurately quantified within 20 min using a water-acetonitrile gradient, containing 1% phosphoric acid. The presented HPLC method may be used to affirm the accuracy of optical tests.
