Ruku-ruku leaves are used to remove distinctive odors from fish in some cuisine of West Sumatra. The characteristic odor comes from secondary metabolites especially essential oils. Therefore, secondary metabolites in ruku-ruku leaves have the potential to be further investigated as a source of bioactive compounds. The phytochemical screening of ruku-ruku leaves is a preminilary qualitative test that needs to be done to maximise its function as a medicinal plant. Based on the result data, there are some different result of flavonoid, steroids, and triterpenoids identification. Ruku-ruku leaves from Pesisir Selatan and Padang Panjang shows less flavonoid compounds tham Payakumbuh, Batusangkar, and Lubuk Alung. Both of this city and Payakumbuh also gives less steroids and triterpenoids. The factor influencing this result is caused by several factors, namely temperature, humidity, light exposure, and salinity.

“…In general, defoliation enhanced polyphenol concentration only at the highest S fertilization rate (120 kg ha -1 of S) and at 1-or 2-periods of scalar defoliation (1YouD, 2YouD, 1OldD and 2OldD treatments). The excessive impairment of photosynthetic apparatus has probably lowered phenolic biosynthesis which result commonly stimulated by mechanical stress (War et al, 2012;Borges et al, 2017). The ascorbate-glutathione (AsA-GSH) pathway has been extensively evidenced to efficiently remove/metabolize ROS and/or their reaction products (Anjum et al, 2012).…”

Experiments were carried out to study patterns of artificial defoliation in radish in combination with sulphur (S) fertilization, to evaluate the contribution of younger and older leaves on plant growth and phenolics accumulation in storage roots. Biomass accumulation and partitioning were related to leaf age, magnitude and timing of the clipping treatments. Older leaves increased biomass production and translocation into the storage organ; besides, they induced higher accumulation of phenolic compounds compared to the younger leaves. The highest S fertilization rate (120 kg ha-1) significantly enhanced the polyphenols accumulation, as well as the antiradical activity. The modulation of S inputs in combination with slightly induced stress from defoliation could effectively enhance the concentration of some important phytochemicals, providing higher nutritionally improved vegetables, without affecting yield.

“…Role of nutrients. Biosynthesis of secondary plant metabolites is influenced due to the content of soil macronutrients, and several deprival treatments have been designed under different experimental conditions, including hydroponia eliminating one or several nutrients (Verma & Shukla 2015, Borges et al 2017. We have focused in the role of Ca 2+ and K + , since are the limiting nutrients in the soils where the tropical tree Calophyllum brasiliense grows.…”

“…In order to determine differences among both locations, soil samples were obtained from the first 30 cm. Several parameters were determined: pH, electric conductivity, Biosynthesis of secondary plant metabolites is under genetic control, but may differ among species due to environmental conditions, such as temperature, precipitation, UV radiation, wet and dry season (Akula & Ravishankar 2011, Pavarini et al 2012, Lim et al 2017, fungal infections (Churngchow & Rattarasarn 2001), and owing to the content of soil macro and micronutrients (Verma & Shukla 2015, Sampaio et al 2016, Borges et al 2017.…”

Background: The influence of soil nutrients on biosynthesis of secondary metabolites from tropical trees has been poorly investigated.Questions: Does the deprival of Ca2+ and K+ influence the production of pharmacologically active compounds in the seedling of Calophyllum brasiliense?Species study: Calophyllum brasiliense Cambess.Study site: Los Tuxtlas, Veracruz, Mexico; November 2005 to November 2009.Methods: The seedlings were obtained from seeds and subjected to different hydroponic treatments: 1) modified Hoagland solution (MHS), 2) MHS-Ca2+, and 3) MHS-K+. Growth, height, foliar biomass, and HPLC analysis were performed after 7 months.Results: Under hydroponic conditions Ca2+ and K+ deficiency induced the mortality of 53 % and 28 % of the seedlings, respectively. The foliar biomass, and plant height of the survivors were also drastically reduced. MHS-K+ treatment induced a 15, 4.2 and 4.3-fold decrease for calanolides B, C, and apetalic acid in the leaves, respectively. MHS-Ca2+ treatment induced a decrease of 4.3, and 2.4-fold for calanolide B, and C, respectively.Conclusion: Ca2+ is essential for survival of C. brasiliense seedlings under hydroponic conditions, Ca2+ and K+ are critical for growth, foliar production, and biosynthesis of apetalic acid, and calanolide B.
