Received: 13 April 2019; Accepted: 22 May 2019; Published: 29 May 2019 Abstract: Some species of the Ericaceae family have been intensively studied because of the beneficial health impact, known since ancient times, of their chemical components. Since most studies focus on the effects of fruit consumption, this review aims to highlight the phenolic components present in the leaves. For this purpose, five species from Ericaceae family (bilberry—Vaccinium myrtillus L., lingonberry—V. vitis-idaea L., bog bilberry—V. uliginosum L., blueberry—V. corymbosum L. and bearberry—Arctostapylos uva-ursi L.) were considered, four of which can be found in spontaneous flora. The chemical composition of the leaves revealed three major phenolic compounds: chlorogenic acid, quercetin and arbutin. The health promoting functions of these compounds, such as antioxidant and anti-inflammatory properties that could have preventive effects for cardiovascular disease, neurodegenerative disorders, cancer, and obesity, have been exemplified by both in vitro and in vivo studies in this review. -

COVID-19 has devastating effects on people in all countries and getting worse. We aim to investigate an in-silico docking analysis of phytochemical compounds from medicinal plants that used to combat inhibition of the COVID-19 pathway. There are several phytochemicals in medicinal plants, however, the mechanism of bioactive compounds remains unclear. These results are obtained from in silico research provide further information to support the inhibition of several phytochemicals. Methods Molecular docking used to determine the best potential COVID-19 M pro inhibitor from several bioactive compounds in Moringa oleifera, Allium cepa, Cocos nucifera, Psidium guajava, and Eucalyptus globulus. Molecular docking was conducted and scored by comparison with standard drugs remdesivir. ADME properties of selected ligands were evaluated using the Lipinski Rule. The interaction mechanism of the most recommended compound predicted using the STITCH database. -
Structural Requirements of Flavonoids and Related Compounds for Aldose Reductase Inhibitory Activity
788 Chem. Pharm. Bull. 50(6) 788—795 (2002) Vol. 50, No. 6 Structural Requirements of Flavonoids and Related Compounds for Aldose Reductase Inhibitory Activity Hisashi MATSUDA, Toshio MORIKAWA, Iwao TOGUCHIDA, and Masayuki YOSHIKAWA* Kyoto Pharmaceutical University; Misasagi, Yamashina-ku, Kyoto 607–8412, Japan. Received January 15, 2002; accepted February 13, 2002 The methanolic extracts of several natural medicines and medicinal foodstuffs were found to show an in- hibitory effect on rat lens aldose reductase. In most cases, flavonoids were isolated as the active constituents by 5 bioassay-guided separation, and among them, quercitrin (IC50 0.15 mM), guaijaverin (0.18 mM), and desmanthin- 1 (0.082 mM) exhibited potent inhibitory activity. Desmanthin-1 showed the most potent activity, which was equiv- alent to that of a commercial synthetic aldose reductase inhibitor, epalrestat (0.072 mM). In order to clarify the structural requirements of flavonoids for aldose reductase inhibitory activity, various flavonoids and related com- pounds were examined. The results suggested the following structural requirements of flavonoid: 1) the flavones and flavonols having the 7-hydroxyl and/or catechol moiety at the B ring (the 39,49-dihydroxyl moiety) exhibit the strong activity; 2) the 5-hydroxyl moiety does not affect the activity; 3) the 3-hydroxyl and 7-O-glucosyl moieties reduce the activity; 4) the 2–3 double bond enhances the activity; 5) the flavones and flavonols having the cate- chol moiety at the B ring exhibit stronger activity than those having the pyrogallol moiety (the 39,49,59-trihy- droxyl moiety). Key words aldose reductase inhibitor; flavonoid; structural requirement; desmanthin-1; quercitrin; guaijaverin Aldose reductase as a key enzyme in the polyol pathway is aerial parts of Centella asiatica (Umbelliferae),11) and the reported to catalyze the reduction of glucose to sorbitol. -

Pollen shape and size were observed under a light microscope (LM). Number of apertures and exine ornamentation were examined using scanning electron microscope (SEM). Closely related plant species had similar pollen morphology. Among the 28 species studied, pollen size varied from small to very large (range 10–200 µm) and their shapes were prolate-spheroidal, prolate, oblate, suboblate, and oblate-spheroidal. Some species had inaperturate pollen grains; the remainders were monoaperture, triaperture or polyaperture. Both colpate and porate apertures were found. -

Embryonic cell lines of Larix kaempferi (Lamb.) Carr overexpressing LaMIR166a were obtained in our previous study. Here, a combination of de novo transcriptomics and extensively targeted metabolomics was used to study the transcriptional profiles and metabolic changes in wild-type and LaMIR166a-overexpressed embryonic cell lines. A total of 459 metabolites were found in the wild-type and transgenic cell lines. Compared to those in the wild-type cell lines, transcripts and metabolites were significantly altered in the LaMIR166a-overexpressed cell lines. -

Identification of Multiple Constituents in Shuganjieyu Capsule and Rat
Original Research Paper Identification of Multiple Constituents in Shuganjieyu Capsule and Rat Plasma after Oral Administration by Ultra-Performance Liquid Chromatography Coupled with Electrospray Ionization and Ion Trap Mass Spectrometry Y. C. Xiao, L. T. Liu, J. J. Bian, C. Q. Yan, L. Ye, M. X. Zhao, Q. S. Huang, W. Wang, K. Liang, Z. F. Shi and X. Ke* Chengdu Kanghong Pharmaceutical Co. Ltd., Chengdu, Sichuan 610036, P.R. China Received: 06 August 2016; accepted: 18 October 2016 Shuganjieyu (SGJY) capsule is a classical formula widely used in Chinese clinical application. In this paper, an ultra- performance liquid chromatography coupled with electrospray ionization and ion trap mass spectrometry has been established to separate and identify the chemical constituents of SGJY and the multiple constituents of SGJY in rats. The chromatographic separation was performed on a C18 RRHD column (150 × 2.1 mm, 1.8 μm), while 0.1% formic acid–water and 0.1% formic acid–acetonitrile was used as mobile phase. Mass spectral data were acquired in both positive and negative modes. On the basis of the characteristic retention time (Rt) and mass spectral data with those of reference standards and relevant references, 73 constituents from the SGJY and 15 ingredients including 10 original constituents and 5 metabolites from the rat plasma after oral administration of SGJY were identified or tentatively characterized. This study provided helpful chemical information for further pharmacology and active mechanism re- search on SGJY. Keywords: Constituents, rat plasma, UHPLC–ESI–MS/MS, Shuganjieyu capsule 1.
