“…The leaves are used in the preparation of green tea. Traditionally S. thea is used in the preparation of herbal medicine for the treatment of hepatitis and fever in China and Korea [ 3 , 4 , 5 ]. Various bioactive compounds such as friedelin, synergic acid, betasitosterol, daucosterol, gluco-synrigic acid, and taraxerol were isolated from the aerial parts of S. thea [ 6 ].…”

Sageretia thea is used in the preparation of herbal medicine in China and Korea; this plant is rich in various bioactive compounds, including phenolics and flavonoids. The objective of the current study was to enhance the production of phenolic compounds in plant cell suspension cultures of Sageretia thea. Optimum callus was induced from cotyledon explants on MS medium containing 2,4-dichlorophenoxyacetic acid (2,4-D; 0.5 mg L−1), naphthalene acetic acid (NAA, 0.5 mg L−1), kinetin (KN; 0.1 mg L−1) and sucrose (30 g L−1). Browning of callus was successfully avoided by using 200 mg L−1 ascorbic acid in the callus cultures. The elicitor effect of methyl jasmonate (MeJA), salicylic acid (SA), and sodium nitroprusside (SNP) was studied in cell suspension cultures, and the addition of 200 µM MeJA was found suitable for elicitation of phenolic accumulation in the cultured cells. Phenolic and flavonoid content and antioxidant activity were determined using 2,2 Diphenyl 1 picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethybenzothiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP) assays and results showed that cell cultures possessed highest phenolic and flavonoid content as well as highest DPPH, ABTS, and FRAP activities. Cell suspension cultures were established using 5 L capacity balloon-type bubble bioreactors using 2 L of MS medium 30 g L−1 sucrose and 0.5 mg L−1 2,4-D, 0.5 mg L−1 NAA, and 0.1 mg L−1 KN. The optimum yield of 230.81 g of fresh biomass and 16.48 g of dry biomass was evident after four weeks of cultures. High-pressure liquid chromatography (HPLC) analysis showed the cell biomass produced in bioreactors possessed higher concentrations of catechin hydrate, chlorogenic acid, naringenin, and other phenolic compounds.

“…Thus, whitening agents from natural sources are preferred and tend to dominate the cosmetic market [ 21 ]. Sageretia thea , belonging to the Rhamnaceae family, has long been recognized as a medicinal herb in Korea and China [ 22 23 24 25 ]. Several studies have demonstrated that the leaves of Sageretia thea have antioxidant activity [ 22 23 ] and have been used to treat itching, boils, and inflammation of the skin caused by lacquer poison in China [ 25 ].…”

BACKGROUND/OBJECTIVESSageretia thea is traditionally used as a medicinal herb to treat various diseases, including skin disorders, in China and Korea. This study evaluated the inhibitory effect of Sageretia thea fruit on melanogenesis and its underlying mechanisms in B16F10 mouse melanoma cells. The active chemical compounds in anti-melanogenesis were determined in Sageretia thea.MATERIALS/METHODSSolvent fractions from the crude extract were investigated for anti-melanogenic activities. These activities and the mechanism of anti-melanogenesis in B16F10 cells were examined by determining melanin content and tyrosinase activity, and by performing western blotting.RESULTSThe n-hexane fraction of Sageretia thea fruit (HFSF) exhibited significant anti-melanogenic activity among the various solvent fractions without reducing viability of B16F10 cells. The HFSF suppressed the expression of tyrosinase and tyrosinase-related protein 1 (TRP1). The reduction of microphthalmia-associated transcription factor (MITF) expression by the HFSF was mediated by the Akt/glycogen synthase kinase 3 beta (GSK3β) signaling pathway, which promotes the reduction of β-catenin. Treatment with the GSK3β inhibitor 6-bromoindirubin-3'-oxime (BIO) restored HFSF-induced inhibition of MITF expression. The HFSF bioactive constituents responsible for anti-melanogenic activity were identified by bioassay-guided fractionation and gas chromatography-mass spectrometry analysis as methyl linoleate and methyl linolenate.CONCLUSIONSThese results indicate that HFSF and its constituents, methyl linoleate and methyl linolenate, could be used as whitening agents in cosmetics and have potential for treating hyperpigmentation disorders in the clinic.

Sageretia thea (Osbeck) M.C. Johnst (1968) is an important fruit and medicinal species of Rhamnaceae family. The complete chloroplast genome (cp) of Sageretia genus was sequenced and reported for the first time in this study. The cp genome had a total length of 161,352 bp, consisting of a largesingle-copy (LSC) region of 89,802 bp, a small single-copy (SSC) region of 18,914 bp, and a pair of inverted repeat (IR) regions totaling 26,318 bp. The plastid genome contained 129 genes, including 84 protein-coding genes, 37 tRNA genes, 8 rRNA genes. The overall GC content of the genome was found to be 37.10%. Phylogenetic analysis based on comparison with 27 chloroplast genomes revealed that S. thea is closely related to genera Rhamnus and Berchemia. The findings of this study can provide fundamental insights for the conservation, exploitation, and systematic genomic investigation of Rhamnus plants.
