Compounds AL-1, AL-14, and AL-17 were isolated from the genus Apocynum and AL-1, AL-7, AL-14, AL-17, AL-18 and AL-22 were isolated from A. lancifolium for the first time. Additionally, compounds CT-1, CT-2, CT-3, CT-5, CT-12, CT-17, 3-(3,4-dihydroxyphenyl)-1-(2,3,4-trihydroxyphenyl)-2-hydroxyprop-2-en-1-one, okanin-3′-(3″,4″-dihydroxybenzamide), CT-21, 2-propenoic acid, 3-(3-hydroxy-4-methoxyphenyl), methyl ester CT-23 were identified from the genus and species of C. tinctoria for the first time. HPLC analysis for quantification of some major flavonoids and chalcones was performed. Under the optimized HPLC conditions mentioned in experimental section, best separation of A. lancifolium and C. tinctoria extracts were obtained in 90 min with method 2, Waters sunfire C18 column 4.6×250mm, 5 μm, delivered by acetonitrile/methanol/ 0.2% formic acid in water and detection at 210, 254 and 360 nm. This condition yielded critical separation for kempferol, quercetin, astragalin, trifolin, hyperoside, nicotiflorin, butein, 3-(3, 4-dihydroxyphenyl)-1-(2, 3, 4-trihydroxyphenyl)-2-hydroxyprop-2-en-1-one, okanin and marein.A. lancifolium and C. tinctoria are wildly used in traditional Uighur medicine for the treatment of hypertension, diabetic and hypolipidaemia. In this study, the pharmacological effects including free radical scavenging activity by using DPPH, antidiabetic effects against Protein Tyrosine Phosphatase 1B (PTP-1B), antimicrobial activities against bacterial and fungal pathogens such as S. aureus (ATCC 6538), E. coli (ATCC 11229) and C. albicans (ATCC 10231), anti-vitiligo activity against B16 cell, and anti-cancer activities against breast cells MCF-7, the cervical cancer cells Hela, the prostate cancer PC-3 and the adenocarcinomic human alveolar basal epithelial cells A549, of obtained individual compounds and bioactive fractions were tested. Results indicated that the isolated compounds and bioactive crude extracts delivered promising antioxidation, antidiabetic, antitumor and antivitiligo activities.Separation and purification of the total flavonoids using various macroporous resins was also attempted. Under optimized static adsorption-desorption process obtained by single factor and orthogonal array design methods, HPD-300 macroporous resin gave the most amount of total flavonoids from the 70% EtOH extract of the flowers of the investigated plants.
