Abstract
Summary
Introduction: Aldose reductase (AR) is an enzyme that catalyzes the reduction of glucose to sorbitol responsible for the development of diabetic complications like cataracts. Medicinal plants contain several phytocompounds that can inhibit this enzyme.
Objective: The purpose of this review is to cite medicinal plants that have been tested for their ability to inhibit aldose reductase and consequently prevent cataracts and classify the major isolated compounds that have this activity.
Methods: We reviewed 154 articles published between 1954 and 2020 in English via three databases: ScienceDirect, Web of Science, and PubMed. We have classified the plants that showed a significant anti-cataract effect, in the form of a list including the scientific and family names of each plant. Also, we have cited the IC50 values and the active constituents of each plant that showed inhibitory activity towards AR.
Results: We have described 38 herbs belonging to 29 families. Besides, 47 isolated compounds obtained from the cited herbs have shown an AR inhibitory effect: luteolin, luteolin-7-O-β-D-glucopyranoside, apigenin, 3,5-di-O-caffeoyl-epi-quinic acid, delphinidin 3-O-β-galactopyranoside-3’-O-β-glucopyranoside, 3,5-di-O-caffeoylquinic acid methyl ester, andrographolide, 1,2,3,6-tetra-O-galloyl-β-D-glucose, 1,2,4,6-tetra-O-galloyl-β-D-glucose, 7-(3-hydroxypropyl)-3-methyl-8-β-O-D-glucoside-2H-chromen-2-one, E-4-(60-hydroxyhex-30-en-1-yl)phenyl propionate, delphinidin 3-O-β-galactopyranoside-3’,5’-di-O-β-glucopyranoside, 1,2,3-tri-O-galloyl-β-D-glucose, 1,2,3,4,6-penta-O-galloyl-β-D-glucose, 1,2,6-tri-O-galloyl-β-D-glucose, 2-(4-hydroxy-3-methoxyphenyl)ethanol, (4-hydroxy-3-methoxyphenyl)methanol, trans-anethole, gallic acid 4-O-β-D-(6’-O-galloyl)-glucoside, β-glucogallin, puerariafuran, quercetin, gallic acid 4-O-β-D-glucoside, 2,5-dihydroxybenzoic acid, 4-(4-hydroxy-3-methoxyphenyl)-2-butanone, protocatechuic acid, trans-cinnamic acid, gallic acid, p-coumaric acid and syringic acid.
Conclusion: natural therapy becomes an interesting alternative in the treatment and prevention of cataract by using medicinal plants rich in active compounds considered as AR inhibitors.

Abstract
A new phenylethanoid, hebitol IV (1), along with fifteen known glycosides (2-16), were isolated from water extract of the flower buds of Buddleja officinalis. Their structures were elucidated on the basis of 1 D-NMR, 2 D-NMR and MS data. Molecular docking showed the potential activities of the natural products against VEGFR-2. Bioassay results revealed that the compounds 10 and 14 exhibited strong inhibitory activity against VEGFR-2 with IC50 values of 0.51 and 0.32 μM, respectively. Moreover, the potential retinal protective effects of 10 and 14 were then investigated in the mouse model featuring bright light-induced retinal degeneration. The results demonstrated remarkable photoreceptor protective activities of 10 and 14 in vivo.

Rapid and comprehensive profiling of α-glucosidase inhibitors in Buddleja Flos by ultrafiltration HPLC-QTOF-MS/MS with diagnostic ions filtering strategy. Food Chem 2020; 344:128651. [PMID: 33243557 DOI: 10.1016/j.foodchem.2020.128651] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 11/12/2020] [Accepted: 11/12/2020] [Indexed: 12/29/2022]
Abstract
Buddleja Flos is used as yellow rice colorant and a well-known traditional Chinese medicine. But its biochemical profiling is still lack due to complex matrix. Here, ultrafiltration high-performance liquid chromatograph-quadrupole time-of-flight tandem mass spectrometry (HPLC-QTOF-MS/MS) with diagnostic ions filtering strategy was proposed for rapid and comprehensive investigation of its α-glucosidase inhibitors. As a result, 33 bioactive compounds (13 phenylethanoid glycosides and 20 flavonoids) were successfully screened and identified. In addition, α-glucosidase inhibitory activities of twenty-two references were verified. Six flavonoid aglycones (4, 28, and 30-33) showed excellent α-glucosidase inhibitory activities (IC50, from 5.11 ± 0.85 to 32.49 ± 9.76 μg/mL), much higher than that of acarbose (IC50, 195.49 ± 10.05 μg/mL). Five flavonoid-monoglycosides (7, 12, 13, 20, and 22) presented moderate inhibitory activities with IC50 from 160.98 ± 23.19 to 249.37 ± 35.83 μg/mL. Results showcased the high efficiency of proposed strategy in profiling of bioactive compounds from natural products.
