“…The higher levels of avonoid during winter season can be possibly due to cold and water stress during the period. Metabolic cost gets abated during leaf senescence that appears in winter (Reimberg et al, 2009;Zietz et al, 2010). The concentrated and retrieved metabolites from senescing tissues might have contributed for the observed trend in the differences in avonoids in the plant samples.…”

Evolvulus alsinoides (Linn.) Linn. is referred as “brain tonic” in Asia and America owing to its activity on the central nervous system. The plant is also found to possess ample of medical activities has been extensively used as traditional medicine in various culture aspects. In the present investigation, the impact of altitude and season of harvest on the phytochemicals and biological activities of E.alsinoides (Linn.) Linn. has been studied. The root, stem and leaves of the plant collected from different altitudes in the Western Ghats of Sathyamangalam, Tamilnadu during the month of July and December, 2016. The primary and secondary metabolites were analysed qualitatively and quantitatively using standard protocols. Minitab 17 Statistical software package was used for Statistical analysis. The altitude and month of plant harvest has an impact on the accumulation of the primary and secondary metabolite in the root, stem and leaves. The leaf samples are found to possess significant antioxidant activities which is further validated by the cytotoxicity activity on SH-SY5Y Neuroblastoma cell line with an IC50 of 119.783 ± 0.06 µg/ml. Isolation of individual molecules and its authentication on the biological activity could give prolific results.

Timely harvesting is an important prerequisite for quality standardization in the traditional Chinese medicine industry. To determine the harvest time of Artemisia argyi and clarify the influence of meteorological factors (MFs) on the harvest time, we selected two excellent germplasm resources, namely, “Nanyang 1” (NY) and Luoyang Artemisia argyi (LY), as examples. We examined the changes in yield, quality, and related traits on 11 sampling dates (SDs) after the six true-leaf stage. Additionally, we analyzed the relationship between eight MFs on different SDs and yield, as well as quality indices. The results show that the SDs and MFs have a significant impact on yield and quality. The dynamic changes in growth traits and dry matter accumulation characteristics of NY and LY were basically consistent. From 75 to 90 d, Artemisia argyi was in the middle and late stages of the transition from vegetative growth to reproductive growth, during which the amount of dry matter accumulation stabilized. The leaves are the most representative medicinal part, with the comprehensive values of the LY leaf yield and main medicinal ingredient contents reaching their maximum at 75 d; the comprehensive values of the NY leaf yield and main volatile ingredient contents reached their maximum at 75 d, while the comprehensive value of the flavonoid and phenolic acid contents reached their maximum at 90 d. Therefore, LY is suitable for harvesting at 75 d, while NY can be harvested at either 75 or 90 d, depending on the harvest goals. In addition, the mean daily minimum temperature (MDMNT), effective accumulated temperature above 10 °C (≥10 °C EAT), and mean temperature daily range (MTDR) were found to be key MFs affecting harvest time. The dry matter accumulation of the roots and stems was significantly positively correlated with the MDMNT (p < 0.01). The dry matter accumulation of the leaves was significantly positively correlated with ≥10 °C EAT (p < 0.05). The total volatile oil content was significantly positively correlated with the MTDR (p < 0.05). These show that meteorological factors affect the harvest time in production practice. This study provides scientific support for determining the harvest time and managing the cultivation of Artemisia argyi.
