The active methanol extracts were successively partitioned with organic solvents such n-hexane, ethyl acetate and butanol to yield organic layers. Among of the resulting organic layers, n-hexane and ethyl acetate layers of the two plants displayed effective inhibition against various filamentous fungal and bacterial growth. Through bioassay guided isolation, 1,8 dihydroxy anthraquinones and their derivatives were isolated from those bioactive layers using silica gel, reverse phase and sephadex LH20 column chromatography.

The research aimed to assess the effects of methyl jasmonate (0.25, 0.5, and 1.0 mM MeJA) on weight loss and phytochemical compounds of kiwifruit (Actinidia deliciosa cv. ‘Hayward’) throughout the cold storage and shelf life. Kiwifruits were stored at 0 ± 0.5°C and 90 ± 5% RH for 180 days, and at 20 ± 1.0°C and 80 ± 5% RH for 5 days in shelf life conditions. During cold storage, weight loss was significantly lower (P < 0.05) in 0.25 and 1.0 mM MeJA treatments than those of control and 0.5 mM MeJA treatments. The highest flesh firmness was determined in MeJA-treated fruits.
