“…Light is one of the environment factors that affect secondary metabolites synthesis [36,37]. Shiga, Shoji [38] have reported that red light illumination enhanced Rosmarinic acid content and antioxidant activities in Ocimum basilicum L plants as compared to blue light illumination.…”

Curcuma longa, commonly known as curcuma or turmeric is a perennial herbaceous plant native to Indian subcontinent and Southeast Asia. Its underground part, referred as rhizome, is used for vegetative propagation and source for remedies for various illnesses. Curcuminoid and volatile oils are the major active components found in turmeric, the yellow power obtained from the ground rhizome. He-Ne laser irradiation has been used as biostimulator device to enhance plant growth. In this study, we have pre-treated the curcuma rhizomes with 5, 10-or 15-min He-Ne laser irradiation. Laser pre-treated and non-treated rhizomes were then cultivated in greenhouse for 8 months. The growth parameters, photosynthetic pigment contents, rhizomes yield were measured. The phytochemical compositions of rhizomes from different treatment groups were measured by gas chromatography mass spectrometry and compared. Effects of laser on DNA polymorphism was assessed by ISSR markers. Our results indicated that laser pre-treatments on rhizomes enhanced curcuma plant height, number of roots and rhizomes, rhizomes diameters, and dried weight of leaves and rhizomes, as well as photosynthetic pigments. The enhancement effects are more prominent in 10 min treatment groups. In addition, laser treatment also alters the phytochemical compositions of ethanol extract from the rhizomes. Interestingly, our study has revealed that laser treatment had resulted in DNA polymorphism as shown from the analysis by ISSR markers.

“…Iler plant in the lowland of Karanganyar have a various content of flavonoids, which may influenced by biotic or abiotic factors [17]. It was known that biotic and abiotic conditions can affect the growth and yield of plant secondary metabolites, in example, the effect of climate change on the presence of pollinators such as butterflies, bees and the effect on soil affect the productivity of plant metabolites.…”

Objective: Iler is an ornamental plant that can be used as a medicinal plant. An effort to increase the flavonoids content was done by planting Iler in the lowlands with the hope that it can increase the secondary metabolites contained to meet the needs of flavonoids obtained from nature. Methods: This research was conducted in Tegal Gedhe Village, Karanganyar Regency with an altitude of 182 m above sea level with Brown Mediterranean soil types. The study used a completely randomized block design. The treatment used consists of one factor which was four accessions of iler plants. Analysis of iler extract was done using ethanol, while analysis of thin layer chromatography (TLC) used the n-hexane:ethyl acetate (6:4) and analysis of total flavonoid were used the AlCl3 method using a spectrophotometer. Results: The total extract content of iler plant in this study was not significantly different, which was accession 1 by 4.009% (±0.36), accession 2 by 5.677% (±0.25), accession 3 by 6.892% (±0.83), and accession 4 by 5.913% (±0.57). TLC analysis shows that accession 1 and accession 2 had 8 spots, while accession 3 and accession 4 formed 9 spots. The highest total flavonoid content was found in accession 2 (5.848% [±0.25]). Conclusion: Accession 2 has a better morphology such as wider leaves characterized by higher source of flavonoids and longer vegetative life than the other three accessions.

“…Outro problema que pode interferir na obtenção de matérias-primas de qualidade oriundas de plantas medicinais é o acúmulo de biomassa que será utilizada para a extração desses princípios ativos, pois a quantidade pode não refletir qualidade. Vários fatores ambientais podem afetar a produção dessa biomassa, pois as plantas são constantemente influenciadas no metabolismo secundário do vegetal, interferindo no acúmulo de biomassa e na produção de princípios ativos das espécies medicinais (WU et al, 2016;TAKSHAK;AGRAWAL, 2019;THAKUR et al, 2019). Portanto, há necessidade de melhorar o rendimento das culturas, bem como o entendimento de práticas específicas que possam auxiliar no manejo (BENSON; MORGENROTH; KOESER, 2019;MASHAMAITE;DUBE;PHIRI, 2019).…”

Para se obter a melhor qualidade terapêutica e produtividade das plantasmedicinais, o manejo adequado da cultura é fundamental, pois diversosfatores podem interferir. Assim, analisou-se o crescimento das plantas decitronela submetidas a diferentes níveis de cortes na parte aérea e nas raízes.Cinco diferentes proporções de desbaste na raiz (0, 25, 50, 75 e 100%), após145 dias do plantio das mudas e 4 cortes na parte aérea (folhas): sem corte; umcorte aos 145 dias após o plantio (DAP), juntamente com o corte da raiz; um corteaos 228 DAP; e cortes aos 145 e 228 DAP (dois cortes). Foram realizadas quatrocoletas para dados de acúmulo de matéria seca e partição de fotoassimilados.O tratamento com 100% de corte na raiz, mas sem corte nas folhas, aumentouo acúmulo de massa seca em relação aos demais tratamentos, para o últimoperíodo de análise, demonstrando uma recuperação.
